We understand a lot about how the brain gets rewired when learning a new skill by repetitive practice, such as hitting a curveball. However, how learning and experience alter the innate behaviors that we are born with is poorly understood.

It is more common nowadays for people to have their own wearable devices to measure physiological signals like heart rate and respiration to keep track of physical diseases. However, monitoring decline in cognitive functions or development of neurodegenerative diseases, such as Parkinson’s (PD), is still complex and tricky.

While acute pain is an important biological signal in response to injured tissue, chronic pain occurs when the pain signaling outlasts the initial injury and has deleterious effects on health and quality of life. Chronic pain represents an enormous public health burden with few therapeutic options.

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.

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.

    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.

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.

Ion channels in the membranes of neuronal cells are the key regulators of neuronal signaling. An ion channel works as a gate that can open and close to allow specific molecules to enter or leave the cell. One important type of ion channels are voltage-gated sodium channels (NaVs), which are essential for many processes in our brain.

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.

For decades we have known that a wide variety of animals use the earth’s magnetic field for navigation, although the means by which they sense it has remained a mystery. There is a long-standing idea that animals like migratory birds use small magnetic deposits in their beaks to act as a compass, however, this idea remains unverified and is currently questioned by many in the field.

Continuous blood flow to the brain is needed for neural tissues to survive. Noninvasive imaging of cerebral blood flow (CBF) in humans is challenging, but is critically useful to understand normal brain physiology and to help patients with cerebrovascular disorders such as stroke.

This research seeks to understand how our genes encode the instructions for neurons in the neocortex to properly arise during normal brain development. This knowledge will allow scientists to understand how genetic mutations perturb development leading to human disease.

Due to the critical role that dopamine producing neurons play in pathophysiology, it is important to examine the function of its co-released GABA. This research aims to study GABA biosynthesis in midbrain dopamine producing neurons and it’s effect on striatal inhibition.

The aim of this project is to improve the accuracy and reliability of dMRI fiber tracking through comparison with a gold standard that unambiguously relates the measured water diffusion patterns to the underlying tissue structure.

Everyone is well aware of their white adipose tissue and its ability to store excess energy as fat. In fact the efficiency with which it does this has led to obesity and related metabolic diseases becoming the largest single health burden in the United States.

Our ability to remember makes us human, and is essential for acquiring new skills and integrating previous experiences into future decision-making. While it is known that long-term memory (LTM) formation requires new gene expression, we lack a detailed and comprehensive understanding of which genes must be expressed to encode memories, and how these genes change over time during the consolidation of memories.

Spinal cord injury (SCI) is a debilitating condition that affects young adults between the ages of 16 and 30, which leads to lifelong medical and financial burdens. SCI still results in a decreased quality-of-life and lower life expectancy for patients. This is due in part to the lack of a regenerative-based therapeutic approach to treating SCI in the clinic.

G protein-coupled receptors (GPCRs) are proteins that exist within the cell membrane and act to transfer the information encoded within neurotransmitters and drugs into cell responses. GPCRs exist throughout the body in several systems including the nervous system.

Understanding how glia regulate the expression and/or post-translational modification of sodium ion channels may lead to the identification of new pharmaceutical targets for the treatment of pain.

Dr. Daniel Bear propose to augment state-of-the-art neural networks with two biologically-inspired properties: the ability to represent the physical world as it changes over time and the ability to learn from self-created signals rather than explicit human instruction.

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.

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.

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.

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.
