Restoring multi-limb motion in people with paralysis via brain-computer interface
Intracortical brain-computer interfaces (iBCIs) can restore lost communication and motor function for people with severe speech and motor impairment due to neurological injury or disease. iBCIs measure neural activity from the brain, decode this activity into control signals, and use these signals to guide prosthetic devices such as computer cursors and prosthetic arms.
Assessing the generalizability of individual brain models
Cognitive neuroscience has traditionally focused on identifying the neural basis of psychological traits or state effects across large samples of participants. Recently, researchers have pushed towards providing more precise estimates of individual functional organization to better understand both psychological constructs as well as their supporting neural mechanisms.
Next-generation brain imaging in freely moving animals
Calcium imaging in freely behaving animals allows for the tracking of neuronal activity under approximately normal behavioral conditions. However, the slow response time of calcium imaging inhibits high resolution voltage and temporal measurements. To address this issue, modern molecular tools have been developed to optically report the high-speed dynamics of neurons more accurately.
Optogenetic screening of the gut-brain axis via an internal light source
The gut-brain axis is implicated in many essential physiological and psychological functions, ranging from feeding, emotion, motivation, to memory. As a critical component of the gut-brain axis, vagal sensory neurons exhibit distinct projection patterns to target specific visceral organs.
Structural analysis of chloride channel CLC-2
Membrane transport proteins are essential for life. They transport essential nutrients and minerals across the membrane barrier that surrounds each cell in the human body. This transport is necessary for every living process – from eating and breathing to learning and doing daily work.
Topical Hedgehog modulators to enhance motor nerve regeneration after injury and repair
Development and validation of selective novel small molecule therapeutics for Parkinson's Disease
Extended Reality(XR) enhanced behavioral activation for treatment of Major Depressive Disorder
This team has created an extended reality–enhanced implementation of "behavioral activation," one of the most effective forms of evidence-based psychotherapy for major depression. They will use the Neuroscience:Translate award to test the efficacy and scalability of this approach and accelerate the development of extended reality technologies to improve treatment options for major depression.
Autism digital therapy with embedded endpoints and artificial intelligence for progress tracking and adaptive care - Renewal
Development of an extracochlear neurostimulation device to restore hearing – Renewal
Sensorineural hearing loss is an increasingly prevalent condition that causes disability to over a third of US adults aged over 65. This team is developing a breakthrough device to restore high-frequency hearing that preserves residual hearing through a reversible and minimally invasive approach.
Remote reliable measurements of movement using bluetooth enabled engineered keyboard for diagnosis of neurological diseases - Renewal
This team is developing a device that will enable accurate diagnosis of Parkinson’s disease via telemedicine. They initially introduced the technology of Quantitative DigitoGraphy (QDG) using a repetitive alternating finger tapping (RAFT) task on a musical instrument digital interface (MIDI) keyboard and will use Neuroscience: Translate funding for the next stage of device development.
Leveraging screenomics to identify mental illness: Detecting bipolar disorder through computational analysis of smartphone screen data
Mental illnesses like bipolar disorder affect millions of people around the world, but early symptoms are often difficult to detect. Working across the disciplines of clinical psychology, communication, and computer science, my research will develop a novel computational tool to identify signals of mania and depression in real-time.
Optimizing computational modeling of traumatic brain injury with machine learning: biomechanics and beyond
Traumatic brain injury (TBI) has become a global health hazard. If undetected, the brain damage of TBI can accumulate, calling for better TBI modeling and warning systems. TBI modeling involves three stages: head impact kinematics, brain deformation, and injuries.
Mechanistic insights into glycerophospholipid metabolism in the lysosome
Phospholipid dysregulation is implicated in the pathogenesis of lysosomal storage disorders (LSDs). We found that glycerophosphodiesters (GPDs) accumulate in lysosomes derived from Batten disease models, a life-limiting LSD whose pathological mechanism remains elusive. GPDs are the degradation products of glycerophospholipid catabolism by phospholipases.
Manipulating inflammation in the aging brain to promote brain resilience
Inflammation is a hallmark of brain aging, yet the source of inflammation in the old brain — and how to eliminate it — is unknown. This team aims to provide insight on how inflammation affects the aging brain that could potentially lead to the generation of new therapies to promote brain resilience.
Mechanistic dissection and therapeutic capture of an exercise-inducible metabolite signaling pathway for brain resilience
Exercise improves cognition and protects against age-associated neurodegenerative diseases, but further research is needed to understand exactly how this occurs. This project aims to pave the way for therapeutics that can capture the benefits of exercise for promoting brain resilience.
Mutant microglia and resilience to Alzheimer’s disease
This project aims to identify how mutant peripheral immune cells that invade the brain might actually reduce Alzheimer’s disease risk. The research will explore how to mimic these cells’ resilience-promoting effects to design new Alzheimer’s therapies.
From gut to brain: reprogramming peripheral macrophages at the intestinal barrier to prevent age-associated inflammation and cognitive decline
This team will investigate whether a decline in intestinal immune cell metabolism drives age-related inflammation and cognitive decline. By replacing aged intestinal macrophages with metabolically healthy ones, they hope to develop a novel approach to enhance cognitive resilience.
Unleashing engineered T cells as disease sensors and therapeutic actuators for neurodegenerative disease
This project will explore whether amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) result from immune cells attacking altered neurons. The team aims to pioneer the use of engineered immune cells as therapies for neurodegenerative disorders.
Role of Proteostasis and Organelle Homeostasis in Brain Resilience during Aging
This team aims to define how and why protein production breaks down in aging cells, leading to disease. This research may lead to new diagnostic and therapeutic approaches against neurodegenerative diseases and potentially aging itself.
Predicting and promoting resilient brain aging trajectories
Using new animal models such as the African killifish, this team aims to develop approaches to predict individual brain aging trajectories early in life based on behaviors that can be modulated to promote healthy memory, executive function and processing speed as well as counter dementia.
Resilience to Synaptic Impairments in Neurodegenerative Disorders
This team will explore the idea that neurotoxic protein aggregates seen in neurodegenerative disorders act at the synaptic connections between cells, and that resilience against these disorders may come from natural synapse-supporting factors that could be transformed into new forms of therapy.
