George Souza

George Souza is an Assistant Professor in the Department of Physiology and Biophysics at the University of Mississippi Medical Center School of Medicine. His research centers on neural mechanisms of cardiovascular and respiratory homeostasis, with emphasis on cerebral blood flow regulation and brain oxygenation during physiological challenges.

His primary research domains include:

• Cardiovascular and Respiratory Neurobiology
• Integrative Neuroscience
• Neural Control of Blood Pressure and Cerebral Perfusion
• Central and Peripheral Respiratory Chemoreception
• Autonomic Function during Sleep-Wake Transitions

Dr. Souza's laboratory employs advanced methodologies including fiber photometry calcium imaging, optogenetic manipulation, and genetically-targeted neuronal ablation in conscious rodent models. Current investigations focus on sympathetic mechanisms governing cerebral perfusion in pathological states such as elevated intracranial pressure and heart failure.

Student mentoring activities and grant funding details remain unspecified in the available departmental information.

Operating from laboratory G354, the research team conducts multimodal physiological recordings including blood pressure, respiration, EEG/EMG, cerebral blood flow, and sympathetic nerve activity in transgenic rodent models during natural behaviors and disease simulations.
