The size and topographic arrangement of retinal ganglion cells in the galago
TL;DR: Analysis of cell areas demonstrates that the central area contains exclusively small to medium-sized cells with large cells first appearing approximately 1 mm from the area centralis, which reveals specialized areas of high ganglion cell density.

Visual resolution and sensitivity of single cells in the primary visual cortex (V1) of a nocturnal primate (bush baby) : correlations with cortical layers and cytochrome oxidase patterns
TL;DR: The response properties of V1 cortical cells in a nocturnal primate is described and the receptive field organization of these cells in relationship to anatomically defined layers and cytochrome oxidase rich blobs and CO poor interblob compartments is examined.

Visual resolution and sensitivity in a nocturnal primate (galago) measured with visual evoked potentials.
TL;DR: Overall visual performance in anesthetized, paralyzed galagos resembled closely that of another nocturnal species, the cat, but peak sensitivity and spatial frequency are slightly lower than found for the behavioral CSF.

Pretreatment with physostigmine, mecamylamine and atropine reduces the impact of soman on the cortical visual evoked potential of the cat.
TL;DR: Pretreatment reduced the degree of VEP depression at suprathreshold doses, indicating a therapeutic effect even in cases of severe exposure.

Depression of the cat cortical visual evoked potential by soman.
TL;DR: The effects of intravenous administration of the anticholinesterase agent soman on the visual evoked potential (VEP) were examined in cats using phase-reversed sine wave grating stimuli of different spatial frequencies and contrasts to reveal dominant changes in gain which are consistent with a modulation of potassium conductance in the cell membrane.
