Electrophysiology of the retina of Periplaneta americana L. 2. receptor sensitivity and polarized light sensitivity

Butler, R.; Horridge, George Adrian


Summary. 1. Retinula cells of Periplaneta in the same state of morphological adaptation differ among themselves in absolute sensitivity by up to 1 log unit (tenfold). 2. Morphologically dark-adapted retinula cells are, on average, ten times as sensitive as light-adapted cells to light on the optical axis. 3. All retinula cells are about 5 times as sensitive to plane polarized light in the plane of its optimum effectiveness as in the orthogonal plane. 4. Retinula cells fall into two groups...[Show more]
