- Abstract
- Hydra's response to a light pulse is a phase shift of the state of bioelectric activity correlated with the
periodic shortening-elongation behaviour. The direction and absolute value of a phase shift depend on
intensity, direction, application phase (along the periodic activity state), and wavelength of the light pulse.
Repetitive pulses entrain the behavioural cycle. The period of the behavioural cycle depends on intensity
and wavelength of steady background illumination; however, the light effect is not exerted isotropically
along all the phases of the behavioural cycle. Inferences are drawn on light influence on the behaviour
pacemaking mechanism. By using polyclonal antibodies against squid rhodopsin, an opsin-like protein has
been identified in the ectodermal layer, presumably in sensory cells. (literal)
