Abstract

The responses of cat lateral geniculate neurons to presentation and withdrawal of a square-wave grating stimulus were measured as a function of the grating orientation. For a given contrast and spatial frequency, the response to a grating varied. always with orientation in all recorded neurons. The mean ratio of the peak response to optimally orientated grating to that elicited by the worst oriented grating for 26 neurons was 3.0±0.3 (S. E.). The optimal orientation of LGN neurons varied with the position of their receptive field centres in the retina and tended to lie parallel to the line jointing the centre of receptive field and area centralis.
