  • Title: Spatial and temporal frequency tuning and contrast sensitivity of single neurons in area 21a of the cat.
    Author: Tardif E, Bergeron A, Lepore F, Guillemot JP.
    Journal: Brain Res; 1996 Apr 15; 716(1-2):219-23. PubMed ID: 8738243.
    Abstract:
    The spatial and temporal selectivities of single neurons in area 21a of the adult cat were investigated using sinusoidal gratings. Optimal spatial frequencies and visual acuity (high cut-off frequency) were fairly low and spatial bandwidth was mainly narrow. Contrast threshold was generally low but a substantial number of cells were only excited by high contrast stimuli. The temporal selectivity suggests that cells responded to a wide range of temporal frequencies.
