Title/Position
Professor, Carver Chair in Neuroscience IV
This laboratory is interested in the neuroanatomy, neurophysiology and neuropharmacology of the central nervous system (CNS) pathways that convey pain, as well as the bulbospinal pathways that mediate the production of analgesia. Our studies emphasize a systems-level approach in which many different...

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...

Title/Position
Assistant Professor
In patient with lewy body disease, the protein alpha-synuclein aggregates, leading to severe multi-system symptoms, including hallucinations, loss of smell, dementia, imbalance, fluctuating confusion, and anxiety/depression. The main research goal of the Aldridge Laboratory is to understand the...

Title/Position
Associate Professor
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...

A high concentration of free ionic zinc in synaptic vesicles is a prominent feature of some of the excitatory pathways in the mammalian forebrain. Despite the wealth of information on its distribution, and role in metalloenzymes and proteins, the role of vesicular zinc remains enigmatic, and serves...

Title/Position
Assistant Professor
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...

Title/Position
Assistant Professor
My research focuses on elucidating central brain mechanisms underlying Alzheimer’s disease, psychosocial disorders, heart failure and sudden cardiac death. The lab uses multidisciplinary approaches including radiotelemetry, optogenetics, neurophysiology, pharmacology, behavioral and molecular...
Jason Radley

Jason J. Radley, PhD

Title/Position
Associate Professor
We combine behavioral, physiological, functional neuroanatomical, and cellular approaches to unravel the neural circuitry that underlies adaptive neuroendocrine responses to stress. Recently we have identified a locus in the basal forebrain that serves as a neural hub for integrating and relaying...

Joel C. Geerling, MD, PhD

Title/Position
Assistant Professor
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...
