[Responses of cat suprasylvian gyrus neurons to light flashes of different wave lengths].

Unit responses in the cat's suprasylvian gyrus to the light flashes of different wavelength were studied. 80% of colour-coding units were found in the suprasylvian gyrus, especially in the Clare-Bishop area. Four groups of neurons differently responding to different spectral regions are distinguished. The possible principle of stimulus wavelength information coding in the suprasylvian units is discussed.
