My research has evolved from the central tenet that visual perception is most efficiently served by multiple, specialized pathways from the retina to the cortex devoted to minimizing redundancy and maximizing sensitivity to specific aspects of visual information. This tenet has led to diverse avenues of research in the primate visual system from the expression of neurotransmitter receptors at the photoreceptor axon terminal to the neurochemistry of local circuits at higher levels of cortical processing. Synaptic organization of cone pathways in the primate retina. Neuronal chemistry and functional organization in primate visual system. Absence of spectrally specific lateral inputs to midget ganglion cells in primate retina.
Foveal cones form basal as well as invaginating junctions with diffuse ON bipolar cells.
M and L Cones in macaque fovea connect to midget ganglion cells by different numbers of excitatory synapses.
