A synthetic ultrasound neural interface for non-invasive and spatiotemporally precise chemogenetic and pharmacological neuromodulation
Controlling brain activity using chemicals and drugs is instrumental in neuroscience research, but current delivery methods for these compounds are imprecise. A proposed synthetic neural interface will allow for more controlled chemical and drug release by using ultrasound to precisely penetrate neural tissue.
Genetically-encoded voltage integrators for stable tagging of activated or inhibited neural ensembles in vivo
A major goal in systems neuroscience is to discover how patterns of activity in neural circuits produce and regulate behavior. Using synthetic biology tools, this team aims to develop first-in-class genetically encoded voltage integrators (GEVIns) capable of sensing and responding to both activation and inhibition of neurons.
In vivo selection for gene mutations that counteract photoreceptor degeneration
Massively parallel microwire arrays for deep brain stimulation
A principled investigation into the heterogeneous coding properties of medial entorhinal cortex that support accurate spatial navigation
Navigation through an environment to a remembered location is a critical skill we use every day. How does our brain accomplish such a task? Over the last few decades, several lines of evidence have suggested that a brain region called medial entorhinal cortex (MEC) supports navigation by encoding information our location and movement within an environment.
Understanding why neurons die in disease
Many neurological diseases feature the death of neurons, but the mechanisms that mediate cell death in these disorders are unknown. Astrogliosis, the response of a cell-type called “astrocytes” to injury, is common to most diseases of the central nervous system (CNS), and recent studies in our lab suggest that some reactive astrocytes may release a protein that is potently toxic to neurons.
High-speed force probes for deconstructing the biophysics of mechanotransduction
The purpose of this collaborative project is to study neuronal mechanisms associated with social stress. In particular we will test whether the energy producing systems, known as mitochondria, in a specific set of brain cells are important to confer resilience to stressful stimuli. This research may lead to treatments of stress and anxiety disorders.
NeuroChoice Initiative (Phase 2)
Stanford NeuroTechnology Initiative (Phase 2)
Our goal is to develop the next generation of neural interfaces that match the resolution and performance of the biological circuitry. We will focus on two signature efforts to spearhead the necessary advances: high-density wire bundles for electrical recording and stimulation, and analog and digital bi-directional retinal prostheses for restoration of vision.
Stanford Brain Rejuvenation Project (Phase 2)
The Stanford Brain Rejuvenation Project is an initiative by leading aging researchers, neuroscientists, chemists, and engineers to understand the basis of brain aging and rejuvenation and how they relate to neurodegeneration.
Neuro-circuit interventional research consortium for understanding the brain and improving treatment
Combining a detailed understanding of brain circuits with technology that modulates neural activity to develop improved ways of treating mental health conditions.
NeuroVision Initiative
The goal is to forge an inter-disciplinary collaboration between physicists, biologists, chemists, and translational medical scientists by inventing new ways of visualizing the brain, from individual molecules to neuronal circuits to entire brain regions, from a normally functioning neuron to a diseased brain.
The NeuroFab: The hub for new ideas in neuro-engineering
Creating an incubator for next-generation neural interface platforms.
Brain-machine interfaces: Science, engineering, and application
Developing technology to interface with the brain and create intelligent prosthetics.
Stroke Collaborative Action Network
Breaches barriers in our understanding of stroke to develop therapies and improve stroke recovery.
Mechanisms of plasma proteins that rejuvenate the aged brain
One in three people will develop Alzheimer’s disease or another dementia during their lifetime, but effective treatment still does not exist despite intense efforts. Recently, blood from young mice has been found to rejuvenate several tissues of old mice, including the brain.
Systematic identification of wiring specificity molecules in Drosophila olfactory circuit using single cell RNA-seq
Precise neural circuit assembly is critical for appropriate function of the nervous system. A functional circuit requires proper targeting and matching of axons and dendrites of pre- and post-synaptic neurons. However, our understanding of the mechanisms that establish wiring specificity of complex neural circuit is far from complete.
Developing a dopamine and neural systems model of anhedonia
More than 60 million people in the United States currently suffer from a serious mental illness, and the associated financial, productivity and human suffering costs are only projected to rise in the near future.
In vivo analysis of cAMP dynamics in developing glial cells
Cyclic adenosine monophosphate (cAMP) is an important intracellular messenger that plays a critical role in the development of the central and peripheral nervous system. However, the mechanisms of action of cAMP in the nervous system development are poorly understood and there are currently no suitable methods to visualize cAMP in the cells of living animals.
Combining electrical and optical measurements on voltage-gated sodium channel toxins
Ion channels in the membranes of neuronal cells are the key regulators of neuronal signaling. An ion channel works as a gate that can open and close to allow specific molecules to enter or leave the cell. One important type of ion channels are voltage-gated sodium channels (NaVs), which are essential for many processes in our brain.
Cognitive remediation of distraction to reduce striatal dysregulation and improve clinical outcomes for individuals with psychosis
The ability to ignore distracters is impaired for individuals with psychosis. This impairment negatively impacts treatment effectiveness and the ability of individuals with psychosis to function fully.
Understanding a complete neural computation in the primate visual system
Understanding the brain requires understanding how the neurons that constitute it perform computations, and how those computations relate to human behavior.
Investigation of synapse formation by novel nanoscale imaging techniques
Synaptic junctions linking individual neurons constitute the fundamental building blocks of our brain. Understanding their inner working is crucial to unravel the mechanisms by which our brain processes information. However, imaging structures at a relevant sub-synaptic level is challenging and has often hampered advances in neuroscience.
The molecular and cellular basis of magnetosensation: quantum effects in biological systems
For decades we have known that a wide variety of animals use the earth’s magnetic field for navigation, although the means by which they sense it has remained a mystery. There is a long-standing idea that animals like migratory birds use small magnetic deposits in their beaks to act as a compass, however, this idea remains unverified and is currently questioned by many in the field.
