J. Puche et al., PROTOCEREBRAL DEAFFERENTATION EFFECTS ON CRAYFISH GLYCEMIC RESPONSE -A PROTOCEREBRAL CIRCADIAN PACEMAKER REGULATES THE HEMOLYMPH SUGAR CONCENTRATION, Revista Espanola de Fisiologia, 49(3), 1993, pp. 151-155
Similar to intact crayfish animals with an isolated protocerebrum exhi
bit a competent control for circadian variations of glucose concentrat
ion in the hemolymph. However, the sudden increase in glucose concentr
ation induced by stressing influences in intact or partially deafferen
ted animals dropped or became totally suppressed in the preparations w
ith isolated protocerebrum.
