Our behaviors are dictated by our intentions, but we have only recently begun to understand how the brain forms intentions to act. The posterior parietal cortex is situated between the sensory and the movement regions of the cerebral cortex and serves as a bridge from sensation to action. We have found that an anatomical map of intentions exists within this area, with one part devoted to planning eye movements and another part to planning arm movements (Andersen and Buneo 2002). The action plans exist in a cognitive form, specifying the goal of the intended movement.  Current studies involve examining decision making, stages in motor planning, coordinate transformations for sensory guided movements and motion perception.  In recent years we have also used the findings from these animal studies to develop brain-machine interfaces using intention signals recorded from the posterior parietal cortex of tetraplegic human participants (Aflalo et al. 2015).

“The overall scientific goal of my research program to understand how nervous systems give rise to flexible, intelligent behavior. The lens through which I address this question is the study of sensory processing: how are robust and flexible neuronal representations of the environment constructed to support behavior? The advantage of sensory neuroscience is that the experimenter has complete control of (or access to) the input and can then track how neural signals relating to this input are transformed as they propagate along the neuraxis. The sensory system of interest is the somatosensory system (of primates), critical to motor behavior and particularly manual behavior. The overall biomedical goal of my research program is to leverage what we learn about natural neural coding to restore the sense of touch to patients who have lost it, namely amputees and tetraplegic patients, by sensitizing bionic hands through electrical stimulation of the nerve or brain. I am the principal architect of the biomimetic approach, which posits that encoding algorithms that mimic natural neural signals will give rise to more intuitive tactile percepts, thereby endowing bionic hands with greater dexterity. Not only are neuroengineering efforts explicitly informed by neuroscientific ones, they also provide an opportunity to test scientific hypotheses using causal manipulations, in this case electrical stimulation of neuronal populations.”

“Today's deep learning solutions scale poorly. Emitting 10,000-fold more carbon to train a deep net only doubles its performance on benchmark tasks. The next doubling in performance will emit as much CO2  as New York City does in a month. In contrast, the brain learns extremely efficiently. A child masters language by the age of 6, having heard at most 65 million words. That’s 15,000-fold less than the trillion words used to train GPT-3. Equivalently, a child that learns language at the same rate as GPT-3 would be 90,000 years old before it could converse fluently. By reverse-engineering how the brain uses so little data to learn, we hope to invent solutions that enable a sustainable technological future.”

Your brain mediates everything that you sense, feel, think, and do. The brain is incredibly complex - each cubic millimeter of your brain contains perhaps a hundred thousand cells, connected by a billion synapses, each operating with millisecond precision. We develop tools that enable the mapping of the molecules and wiring of the brain, the recording and control of its neural dynamics, and the repair of its dysfunction. We distribute our tools as freely as possible to the scientific community, and also apply them to the systematic analysis of brain computations, aiming to reveal the fundamental mechanisms of brain function, and yielding new, ground-truth oriented therapeutic strategies for neurological and psychiatric disorders.

“The focus of our group is on understanding brain function works under both normal and pathological conditions with an ultimate goal of developing techniques for diagnosing and treating some of the most devastating neuropsychiatric diseases. We focus on using approaches which extract information at multiple scales and then combine them into a more complete and meaningful understanding of brain physiology. We feel this multi-scalar, multi-modal approach is particularly powerful for understanding the human brain because of its complexity and architecture which is, by nature, multi-scalar. This information can then be used to design therapeutic interventions including brain-computer (machine) neuroprosthetics.”

“A unique and defining trait of human behavior is our ability to communicate through speech. Our laboratory is interested in determining the basic mechanisms that underlie our ability to perceive and produce speech. While much of this processing has been localized to the peri-sylvian cortex, including Broca’s and Wernicke’s areas, the fundamental organizational principles of the neural circuits within these areas are completely unknown. To address this, our laboratory applies a variety of experimental approaches including psychophysics, local field potential and microelectrode array recordings, electrocortical stimulation, and real-time signal processing. These methods allow us to examine both local circuitry and global network dynamics spanning multiple cortical and sub-cortical regions with unparalleled spatial and temporal resolution in humans. Our central goal is to provide a mechanistic account for the major properties of speech behavior in normal speakers and those with language disorders. Our ongoing research is not only deepening understanding of speech and its disorders, but also is leading directly to safer mapping methods to preserve language function during brain surgery.”

“Broadly speaking, our laboratory investigates how sensory feedback impacts the neural representation of motor intent. One of the major tools we use is the brain-computer interface (BCI). These devices allow us to tap into the output of a network of neurons and use that recorded activity to directly drive a device, like a computer cursor. By creating a defined link between neural activity and behavior, BCIs provide a unique window for probing brain processes that would otherwise remain covert, like learning, adaptation, and the dynamic evolution of the intent signal. Ultimately a basic understanding of these phenomena will not only inform us about the fundamental limits of motor control processes, but will also help propel the development of new neural prosthetic devices. Our research has two main thrusts. First, we develop novel computational and experimental techniques that leverage BCIs as a research tool for investigating the neural mechanisms of sensorimotor adaptation and skill acquisition. Second, we design new BCI decoding algorithms to enhance the performance of these devices and hasten their clinical translation.”

“We take a computational perspective, and ask how motor commands might be produced by recurrently connected networks with strong internal dynamics. We ask whether empirical neural data, collected during the performance of motor tasks, reflects basic computational principles that can be inferred from existing theory. Conversely, we ask when existing theory should be modified to incorporate principles gleaned from examination of empirical data. To pursue this approach, we collaborate extensively with colleagues in the Grossman Center for the Statistics of Mind, and within the Center for Theoretical Neuroscience.”

“We are investigating the neural mechanisms involved in programming and executing hand movements by recording neural activity in monkeys trained to manually track visual targets. We are particularly interested in studying ''pre-motoneuronal'' cells in motor cortex and spinal cord that produce postspike effects on forelimb muscle activity. By knowing both the response patterns of these cells during movements and their output connections to target muscles we can make important causal inferences about their contribution to movements. We are currently using multichannel electrode arrays to investigate interactions between motor cortex sites during movement.”

“We are a diverse group of physicists, mathematicians, computer scientists, bioengineers and neurobiologists, dedicated to this quest. We are motivated by two overarching questions: 1. How do fundamental higher level cognitive phenomena like perception, memory, attention, decision making and motor control emerge from the collective interactions of many dynamical degrees of freedom embedded within networks of neurons and synapses? 2. Can principles of high dimensional statistics and computation provide a unified view of how we as neuroscientists can extract biologically meaningful models of neural systems from large datasets, as well as how neural systems themselves can extract predictive models of their environment from the stream of sensorimotor experience? To pursue these questions, we exploit and extend tools and ideas from a diverse array of disciplines, including statistical mechanics, dynamical systems theory, machine learning, information theory, control theory, and high-dimensional statistics, as well as collaborate with experimental neuroscience laboratories collecting physiological data from a range of model organisms, from flies to humans.”

"The motor network consists of interconnected cortical and subcortical areas. Large scale recordings suggest frameworks for processing such as oscillatory dynamics and cross-area filtering. We aim to delineate the network dynamics of learning and to develop physiologically-inspired neurotechnology to enhance recovery and function. Goal 1. Understand how distributed network activity permits learning and skill consolidation. We are interested in how animals learn new complex and flexible skills. We specifically consider neural processing across awake and sleep in cortex and the basal ganglia. For example, how are awake experiences (task activity) processed during sleep to allow consolidation of a nascent skill (e.g. Gulati et al., Nature Neuro, 2017; Kim et al., Cell 2019)? How does this change with injury (e.g. Kim et al., Cell Reports, 2022)? Goal 2. Neural interfaces to restore neural circuit dynamics. We use principles of network plasticity to integrate bidirectional neural interfaces ("read and write"') into injured brains. We thus aim to restore neural processing and improve function (e.g., Ramanathan et al, Nature Medicine 2018; Khanna et al., Cell, 2021). Goal 3. Translate to patients. In addition to discovering fundamental principles, we are translating our research into clinical neurotechnology (Silversmith et al., Nature Biotechnology, 2021). We co-lead a pilot trial of Brain-Computer Interfaces (BCI) in human subjects with severe motor disability [BRAVO Trial, ClinicalTrials@UCSF]. “

“Our overriding interest is in aging, cognition, and dementia both at the population level and at the level of individual adults. Our research agenda encompasses cognitive change that occurs as a usual concomitant of normal aging and more debilitating impairment that accompanies Alzheimer’s disease and other forms of dementia. Pathological processes that culminate in Alzheimer dementia are believed to begin years, if not decades, before the onset of mental symptoms. For this reason, we are interested in factors that affect cognitive skills at midlife, a time when therapeutic interventions offer the greatest potential of forestalling late-life impairment, as well at older ages, when cognitive impairment more typically first becomes apparent. One research theme pertains to adult women’s health. Here, we continue to examine cognitive consequences of estrogen, testosterone and other hormones, whose concentrations vary with age.”

Making sense of data is possibly the biggest problem in Neuroscience and beyond. We build algorithms to analyze data. We also use theory as well as computational and neural modeling to understand how information is processed in the nervous system, explaining data obtained in collaboration with electrophysiologists and in psychophysical experiments. Lastly, we constrain and develop new technologies aimed at obtaining data about brains. Our conceptual work addresses information processing in the nervous system from two angles: (1) By analyzing and explaining electrophysiological data, we study what neurons do. (2) By analyzing and explaining human behavior, we study what all these neurons do together. Much of our work looks at these questions from a normative or causal viewpoint, asking what problems the nervous system should be solving. This often means taking a Bayesian approach. Bayesian decision theory is the systematic way of calculating how the nervous system may make good decisions in the presence of uncertainty. Causal inference from observational data promises to be a key enabler for progress in science.

“We study the "language" of these control signals and the networks of neurons that produce them. Along with this basic research, we are working to develop neural interfaces that directly connect the brain of a spinal cord injured patient with the outside world. These interfaces will ultimately allow patients to operate a computer or a prosthetic device. They may also bypass the injured spinal cord in order to reactivate paralyzed muscles, or to restore the sense of touch and limb movement."

Repair: We have observed that stimulation within the spinal cord below an injury leads to improved motor function even beyond the period of stimulation. In the uninjured central nervous system, synchronizing stimulation can be used to strengthen connections among neurons via mechanisms of Hebbian plasticity. We are investigating whether intraspinal stimulation, triggered by appropriate cortical activity, is capable of guiding spared pathways to functional targets after spinal cord injury.

“As a systems neurophysiology lab, we are interested in the way neural activity drives behavior. Our goal is to describe organizational principles of the time-varying relation between the firing rates of neurons and the behavior this activity generates. Specifically, our research program centers on the relationship between cerebral cortical activity and arm movement. Over the last 25 years, we have found that there is a very good representation of the armis trajectory in the collective firing pattern of frontal cortical activity. This makes it possible to predict the detailed time course of arm, wrist and finger movement that contains many of the behavioral invariants that are characteristic of movement. Research projects in our laboratory are based on this dynamic representation of behavior. The parameter of time is fundamental in our consideration of movement. We have shown that movement generation takes place continuously the cortical prediction of trajectory precedes movement execution with a time interval that is dependent on the figural components of the hands path.”

“Our research interest is to understand the behavioural, neural, and mechanical aspects of voluntary motor function. We use optimal control theory as a framework to interpret voluntary control which emphasizes the importance of sensory feedback for controlling motor actions. Our studies use the Kinarm robot we invented to quantify planar limb movements. We use small disturbances (usually mechanical, but visual sometimes) to observe how subjects make corrective responses to attain behavioural goals. Effectively, these disturbances allow us to probe the motor circuits to understand the underlying control processes. Most studies quantify changes in muscle electromyographic activity to observe the exact timing when the motor system reflects different functional processes. This research is supported by a grant from NSERC.”

To do so, we work at the interface of machine learning, statistical inference, signal processing, and control theory to develop algorithmic solutions for problems in basic and clinical neuroscience that involve the collection and manipulation of neural signals. Our work combines algorithm development and modeling with in vivo experimental implementation and testing, and is conducted in close collaboration with a variety of experimental labs. Our lab has developed brain-machine interfaces for decoding and closed-loop control of various brain states to restore lost emotional function in mental disorders and lost motor function in neurological injuries and diseases. Some specific problems of interest include dynamic modeling of high-dimensional multiscale brain network activity, decoding of cognitive, motor, or mood states from neural signals, and developing closed-loop neurotechnologies such as closed-loop deep brain stimulation systems and brain-machine interfaces. These closed-loop technologies have the potential to enable personalized therapies for a wide range of neurological and neuropsychiatric disorders.”

“We develop novel biophotonic tomographic technologies for early-cancer detection and functional imaging, using non-ionizing electromagnetic and ultrasonic waves. Unlike ionizing x-ray radiation, non-ionizing electromagnetic waves, such as optical and radio waves, pose no health hazard and at the same time reveal rich contrast mechanisms. Unfortunately, electromagnetic waves in the non-ionizing spectral region do not penetrate biological tissue in straight paths as x-rays do. Consequently, high-resolution tomography that is based on non-ionizing electromagnetic waves alone, as demonstrated by confocal microscopy, two-photon microscopy as well as optical coherence tomography, is limited to superficial imaging within about one optical transport mean free path (~1 mm) of the surface of biological tissue. Ultrasonic imaging, by comparison, provides fine image resolution but has strong speckle artifacts and has no molecular contrast. We have developed ultrasound-mediated imaging modalities by combining electromagnetic and ultrasonic waves synergistically to overcome the above problems. The hybrid modalities yield speckle-free images with high electromagnetic contrast at high ultrasonic resolution in relatively large volumes of biological tissue. Please visit the Research pages to see the specific technologies that we develop.”
