Binocularly driven neurons in the rostral part of the frog optic tectum

  • F. Gaillard


Receptive field (RF) properties of binocular neurons lying in the rostral part of the optic tectum of the frog (Rana esculenta) were studied electrophysiologically using conventional visual stimuli. They were classified into five groups: group 1 neurons have indefinite RF; group 2 neurons are total-field (T6) neurons; group 3 neurons have RFs covering a quadrant of the frontal visual field; group 4 neurons resemble T 1(1) and T 1(3) subclasses described earlier; and finally group 5 neurons look like small-field binocular neurons and are called T7(B). Moreover, RF disparity measurements conducted in all groups suggest that group 4 neurons support the estimation of binocular distance. This problem is discussed.
