Projects
Investigating the evolution of vertebrate pair bonding mechanisms
By performing a molecular and neural network analysis across behaviorally divergent pair bonding species, Dr. Jessica Nowicki will use the power of comparative analysis to reveal core mechanisms that regulate pair bonding.
Forces driving myelin wrapping In oligodendrocytes
Dr. Miguel Garcia believes that identifying the mechanism of myelin wrapping is important in understanding neural development and is a critical first step towards creating much needed therapeutic approaches to stimulate remyelination in patients with demyelinating diseases.
Accelerating maturation of 3D human brain organoid models to study human aging mechanisms.
Dr. Iram will use brain intrinsic and systemic regulators of aging, in an attempt to accelerate maturation of human-derived brain organoids. This has the potential to produce the first ever aged human brain 3D cultures and identify factors which accelerate brain aging.
Ultrasonic neural control and neuroimaging in the awake, mobile, and behaving small rodent
We propose to design a lightweight, wearable system for integrated ultrasonic drug uncaging and fUS neuroimaging to noninvasively pharmacologically modulate a brain target and then image the resultant changes in neural activity without significant motion limitations.
Sensory processing in a pre-seizure state
Genetic tools to determine circuit-specific roles of myelination
These tools will enable us to dissect how myelin contributes to specific brain circuits and types of neurons, bringing us closer to a holistic understanding of how cells in the brain collaborate to build a functional nervous system.
Injectable photovoltaics for a wireless, gliosis-free neural stimulation interface
We believe our research has the potential of generating transformative results for both neuroscience research and neurological applications, also offering strategies to manipulate key intracellular pathways to prevent gliosis in therapeutic neural implants.
Investigating the role of a human-specific repeat element in neuropsychiatric disease risk and cerebellar function
Quantifying auditory-vocal affect in human social communication
This proposal brings together faculty with this diverse expertise to develop the first gold standard test of auditory-vocal affect. Once developed, validated, and normed, we will deploy this test in the clinical context of autism to quantify impairments and direct neurobiological investigation.
How animals keep time annually: molecular mechanisms of the seasonal rhythm
Adaptation to environmental variations is vital for animal survival. While short-lived organisms face unpredictable environmental fluctuations, long-lived animals are subject to regular and generally drastic environmental changes across different seasons.
Engineering nanoscale optical transducers of mechanical signals in the nervous system
Communication between cells in the nervous system regulates the senses, memory, and information processing. Using electrical and biochemical sensors, such as patch clamps, voltage-sensitive dyes, and calcium-sensitive dyes, scientists have mapped with extraordinary detail the interactions of the nervous system.
Characterizing large-scale neural circuit dynamics over long-term recordings
Neural circuits can exhibit remarkable stability (e.g., when supporting long-term memory) as well as flexibility (e.g., when supporting rapid learning).
Identifying the neurobiological underpinnings of meta-learning
Meta-learning, an old concept in psychology, is the ability of humans to improve the way they learn with experience. Our previous experience of learning a skill makes us better at learning another, related skill. For instance, an athlete will learn a new sport faster than someone without the same level of experience in similar learning tasks.
Reprogramming organismal lifespan through modulation of neuropeptidergic circuits
Aging is the number one risk factor for debilitating diseases such as neurodegeneration. Can manipulation of neurons in the brain alter the body’s physiological state to extend lifespan? Neuropeptides are key modulators of short-term homeostasis such as feeding, temperature, and sleep.
Neuronal mechanism underlying spatial navigation in cephalopods
Cephalopods, including the cuttlefish, octopus, and squid, possess one of the most advanced nervous systems among invertebrates. With their advanced nervous systems, cephalopods are able to perform sophisticated behaviors such as navigating in open water to search for food. Yet how their nervous systems accomplish spatial navigation remains completely unknown.
Dissecting curious exploration with self-supervised machine learning
What are the principles that guide curiosity-based exploration? What is the neural circuitry that implements curiosity? How can insights related to the phenomenon of curiosity improve the education and capabilities of humans and artificially intelligent agents? To address these questions, Isaac Kauvar will take an interdisciplinary approach — positioned at the intersection of computer science, neuroscience, and psychology.
Wearable stimulation for sensorimotor rehabilitation
Vibrotactile stimulation provides powerful somatosensory and proprioceptive input to the nervous system.
The role of gene complexity in the evolution and function of nervous systems
Many of the largest, most complex genes in the genome are enriched in the brain and are frequently mutated or misregulated in neurological diseases and disorders such as Alzheimer's disease, autism spectrum disorders, and Rett syndrome.
Genetic access of cell types using viral vectors
Multicellular organisms consist of numerous cell types with specialized biological functions. To understand such complex biological systems, genetic access to each cell type is needed for functional analysis and manipulations.
Mechanisms of myelin membrane expansion
Myelin is the protective covering that surrounds nerve fibers to accelerate communication between different parts of the nervous system. Damage to myelin occurs in diseases such as multiple sclerosis, which compromises nerve signaling and impairs motor and cognitive function.
Rapid brain-wide optogenetic screening with a noninvasive, dynamically programmable in vivo light source
Elucidating the biophysical mechanisms of latrophilin activation in excitatory synapse formation
Mapping the Mitophagy Network in Parkinson’s Disease
We will comprehensively define the gene network associated with mitochondrial dysfunction in Parkinson's disease using a cutting-edge technology, CRISPR, to understand how these nerve cells die in PD and how we can reverse the cell death to treat the disease.
Magnetic Recording and Stimulation of Neural Tissue
We propose a new magnetic sensor that is sensitive to picoTesla-scale fields, a localized magnetic stimulator with small form-factor, and a seamless integration of both systems for applications in experimental and clinical neuroscience.
