Fig. 2. Transient and dyn'amic responses of a tangential neuron (Tan1) to polarized light at varied e-vector orientations. (A) Tangential cell responses (top trace) to 0.2s flashes (at 0.5s-1) of polarized light at varied e-vector angles. The lower trace indicates stimulus timing and e-vector orientation (as described in Fig.1). (B) Response of the same tangential cell to a changing e-vector. The stimulus light (lower trace) comes on at t=1.0s and two cycles of polarizer rotation are separated by a steady-state exposure of 9s (modified from Glantz, 1996b). (C) Comparison of the steady-state (solid line) and dynamic (broken line) responses as a function of e-vector angle. Vertical bars are ± 1.0 S.E.M. Each point is the mean of five observations.
