Effects of extracellular calcium and of light adaptation on the response to dim light in honey bee drone photoreceptors



Effects of extracellular calcium and of light adaptation on the response to dim light in honey bee drone photoreceptors



Journal of Physiology 344: 525-548



Responses to light were recorded with intracellular microelectrodes in superfused slices of drone honeybee retina. Dim light stimuli were used so that the amplitude of the response was linearly related to the number of the photons absorbed, the effects of voltage-dependent mechanisms were negligible and no detectable light adaptation was produced by the stimulus. Lowering the extracellular calcium concentration increased the amplitude and the duration of the response.
