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.

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.

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.

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.

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.

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.

Neural circuits can exhibit remarkable stability (e.g., when supporting long-term memory) as well as flexibility (e.g., when supporting rapid 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.

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.

This team is developing wearable stimulation devices to improve limb function after stroke. The technology includes a tactile stimulation method, and the wireless, lightweight, and low-cost wearable computing devices to apply this stimulation.

Schwann cells (SCs) sort and myelinate peripheral axons, and impairments in either process can cause long-term disability. There are no therapeutic strategies for targeting SC dysfunction, underscoring the need to investigate mechanisms of sorting and myelination. Both processes require highly motile SC cytoplasmic protrusions, but the basis of this motility is unclear.

Absence epilepsy is a form of pediatric epilepsy which causes seizures with brief lapses in awareness. Electron microscopy results in a murine model of absence epilepsy support the hypothesis that maladaptive myelination plays a role in disease progression.

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.

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.

Vibrotactile stimulation provides powerful somatosensory and proprioceptive input to the nervous system.

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.

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.

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.
