title: Protocerebral deafferentation effects on crayfish glycemic response: a protocerebral circadian pacemaker regulates the hemolymph sugar concentration.
abstract: Similar to intact crayfish animals with an isolated protocerebrum exhibit a competent control for circadian variations of glucose concentration in the hemolymph. However, the sudden increase in glucose concentration induced by stressing influences in intact or partially deafferented animals dropped or became totally suppressed in the preparations with isolated protocerebrum.
