Sleep is a critical behavioral state that fulfills essential needs for health, including clearing waste products (e.g., protein aggregates) from the brain. But sleep is not everlasting. As humans age, sleep quality strikingly deteriorates, and this decline is associated with dementias (e.g., Alzheimer’s disease).

With an aging population, neurodegenerative disorders contribute increasingly to our global health burden with no cure or effective treatments. Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two neurodegenerative disorders that are distinct in clinical presentation (ALS impairs movement/breathing, whereas FTD impairs behavior/cognition).

There is one characteristic of all neurodegenerative diseases: the accumulation and aggregation of abnormal proteins in the patient’s brain. These aggregations are thought to induce neuronal cell death and brain degeneration.

The causes of neurodegenerative disorders like multiple sclerosis or Alzheimer’s disease are incompletely understood, hindering our ability to gain precise diagnoses and design effective therapeutics. Understanding how the circadian rhythms regulate myelin-forming precursors will impart unique insights into normal and aberrant myelination and will have a positive impact on developing therapeutic strategies to restructure myelin.

Autism is a highly genetic developmental brain disorder which is characterized by social impairments. Autism affects 1 in 68 US children, with an annual cost in the US of $250 billion dollars. Unfortunately, the basic biology of autism remains poorly understood.

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.
