We present a study of the CNS of Neohelice granulata performed atthe neuronal cluster and neuropil level, describing eyestalk ganglia, thethoracic ganglion and the central brain, with special focus on the latter.This characterization is based on the functional study of the crab nervoussystem during two main phases: visual information processing, and thestorage of memory. The nervous system delineation uses classicalhistological techniques as well as immunohistochemistry to characterizecellular clusters and neuropils. This is the first general description of theN. granulata nervous system as a whole at a neuropil and cellular level.Few representations of the central nervous system of N. granulata havebeen published besides the general scheme published by Bond-Buckup etal. (1991).
