Daniel J. Felleman

Dr. Daniel J. Felleman is a Professor at The University of Texas Health Science Center at Houston, specializing in the organization, function, and plasticity of the primate cerebral cortex. His research focuses on visual processing mechanisms in cortical areas V2, V4, and posterior inferotemporal cortex, with particular emphasis on color and form discrimination.

Research Interests: The laboratory employs optical recording of intrinsic cortical signals and neuroanatomical tracers to map functional modules in primate visual cortex. Key findings include the segregation and integration of color and form inputs in V4, and developmental changes in prefrontal cortex following neonatal temporal lobe damage.

• Neurodevelopmental changes in prefrontal cortex after medial temporal lobe damage
• 3D computer graphics analysis of cortical circuitry

Scientific Contributions: Spanning four decades, his work has established foundational understanding of cortical organization through publications in Nature, Science, and Cerebral Cortex. Recent studies (2014-2024) explore orientation pinwheels in V4 and mutual information analysis in stripe compartments.

Technological Innovations: Developed wireless neural interface systems for primate research (2015), enabling unconstrained behavioral studies. Pioneered difference-image techniques to identify activated cortical regions through chromatic and luminance stimulation.
