Four aspects of the crustacean visual system are investigated:1. the molecular basis of polarized light sensitivity. Discrete transient membrane potentials (bumps) were recorded from retinula cells of a crab, in response to single polarized photons. An analysis of bump rates versus the E-vector of the polarized light stimulus reveals that the rhabdomere's dichroism accounts for the photoreceptor's sensitivity to polarized light.2. The mechanism underlying the shore crab's ability to perceive...[Show more]
