Selectivity to spatial frequencies in the pigeon's optic tectum cells] |

| Authors: | O Hardy D Jassik-Gerschenfeld |
| Abstract: | Extracellular cell recordings in the pigeon optic tectum show a selectivity of response to different sine-wave gratings presented in motion. The optimal frequencies are found to be between 0.4 and 0.9 cycle/degree and are independent of direction, orientation and velocity. |
