Gawne Lab

 
 

This is the personal webpage of Timothy Gawne, Assoc. Prof., Department of Vision Sciences, University of Alabama at Birmingham.  My interests are primarily in the area of how neurons encode and process information, with an especial interest in how the activity of neurons as a function of time (i.e, their dynamics) could play a role in their function.  Much of my work involves recording from single neurons and small groups of neurons in the primate visual system, as well as using electro-encepahlographic (EEG) and magneto-encephalographic (MEG) techniques to investigate similar issues in human subjects.  I have a background in both engineering and physiology, and thus my research involves combined computational and experimental approaches to trying to understand how the brain works at a systems level.


CURRENT PROJECTS:


INFORMATION PROCESSING IN THE CEREBRAL CORTEX: Using a variety of techniques, including single-unit electrophysiology, combined with computer modeling, attempt to use the visual cortex as a model for determining the neural code in the cerebral cortex.


GAMMA-BAND BRAIN ACTIVITY AND NEUROTRANSMITTER METABOLISM IN SCHIZOPHRENIA:  In collaboration with Dr. Adrienne Lahti, UAB Dept. Psychiatry, use a variety of techniques, including magnetoencephalography (MEG) and high-field MRI spectroscopy to evaluate the possible role of aberrant brain rhythms, and disorders of neurotransmitter metabolism, in schizophrenia.


VISUAL CORTICAL EVOKED POTENTIAL: Develop new technologies and methodologies for using the visual cortical evoked potential (VEP) in both clinical diagnosis and basic research.
