Funded Projects

    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 the course of everyday functioning, animals (including humans) are constantly faced with real-world environments in which they are required to shift unpredictably between multiple, sometimes unfamiliar, tasks. But how brains support this rapid adaptation of decision making schema, and how they allocate resources towards learning novel tasks is largely unknown both neuroscientifically and algorithmically.

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. 

Our ability to detect and interpret sounds relies on specialized sensory cells within the snail-shaped hearing organ of the inner ear—the cochlea. These hair cells sense physical movement and then convert that mechanical stimulus into a biological signal that we perceive as sound. These mechano-sensory cells perform this task within microseconds and can do so for sub-nanomechanical stimuli.

Brain data analyses involves many steps and every step is prone to errors and uncertainties. Ignoring uncertainties can potentially leading to overconfident conclusions. To improve reproducibility it is important to propagate errors throughout the analysis.

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.

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.

A hallmark of the motor system is its ability to execute different skilled movements as the situation warrants, thanks to the flexibility of motor learning. Despite many behavioral studies on motor learning, the neural mechanisms of motor memory formation and modification remain unclear.

My proposed visit to the Van De Ville lab is centered on the idea to expand our methods beyond brain tumors to other neurological diseases using the Van De Ville lab’s expertise in neuro-imaging. Imaging genomics has been focused mainly on oncology; however, other neurological diseases can be studied in the same way.

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.

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.

StrokeCog is focused on cognitive problems after stroke. The team leads a study aimed at identifying if neuroinflammation plays an important role in the development of post-stroke cognitive decline.

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.

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.

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.

To understand how sensory information and physiological state integrate to drive decisions and behaviors. Dr. Xiaoke Chen's lab is focusing now on interoception, which is the sense of the physiological condition of the body. This include our abilities to feel hungry or satiated, to sense heightened blood pressure and heart rate during stress, and to discriminate different types of pain.
