We are studying the role of serotonin neurons in mediating the effects of acidosis on brain function and behavior. We have shown that serotonin neurons are exquisitely sensitive to changes in pH. They are close to large arteries in the brain and contribute to the increase in breathing induced by...

Serotonin neurons are mainly localized to the raphe nuclei of the brainstem, but their axons are widely distributed throughout the nervous system and have a ubiquitous role in physiological processes and behavior. Adding to this complexity is the diverse array of high-affinity receptors that bind...

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of death in patients with intractable epilepsy, but specific mechanisms of how a seizure can cause death are poorly understood. Research efforts in my laboratory are focused on using animal models to understand the mechanisms by which...

Homeostasis is a robust form of regulation that allows a system to maintain a constant output despite external perturbations. In the nervous system, homeostasis plays a critical role in regulating neuronal and synaptic activity. Yet the molecular basis of this form of neural plasticity is generally...

Humans spend about a third of their life sleeping. Yet, our understanding of the cognitive, emotional and neurodevelopmental functions of this essential behavior and how these may be disrupted in clinical populations is still very limited. Sleep disturbances are observed in most major psychiatric...

My research interest is the molecular basis of migraine. A hallmark of migraine is altered sensory perception coupled with head pain. To understand the mechanisms underlying these events, we have focused on the neuropeptide calcitonin gene-related peptide (CGRP), whose levels are elevated during...

Dr. Hoth is a board certified clinical neuropsychologist with expertise in aging and cognitive changes associated with chronic medical illnesses. She received her Ph.D. in Clinical Psychology from the University of Iowa and completed both her pre-doctoral internship and a two-year fellowship in...

We study the neural circuits and intraneuronal signaling mechanisms that regulate appetite, body weight, sleep, and cardiorespiratory function in mice and aim to understand how these regulatory processes go awry in metabolic disorders. To this end, we employee state-of-the-art neuroscience...

In the lab, we use genetic techniques to isolate and manipulate neurons that mediate basic physiologic functions including sleep, appetite, bladder control, and thermoregulation. My focus lies in identifying and deciphering previously unknown connections between neurons in the brainstem and other...

I work in the Human Brain Research Laboratory with a team of neurosurgeons and neuroscientists, studying neurosurgical epilepsy patients who undergo electrode implantation for clinical diagnostic purposes. This provides a unique opportunity for direct electrophysiological recordings from the human...
