Interaction between receptive field halves of cells in area 18 of the cat's visual cortex

Interaction between receptive field halves has have investigated in cells from area 18 of the visual cortex of cats light anesthestised with N 2O/O 2 supplemented with pentobarbitone. Interaction within receptive field halves may be facilitatory additive, partially additive, or subtractive, and the organization in one half-field is not predictable from that in the other. Interaction between half-fields may be facilitatory, additive, partially additive, or subtractive and can not be predicted from interaction within halves.
