We present a study of the CNS of Neohelice granulata performed at the neuronal cluster and neuropil level, describing eyestalk ganglia, the thoracic ganglion and the central brain, with special focus on the latter. This characterization is based on the functional study of the crab nervous system during two main phases: visual information processing, and the storage of memory. The nervous system delineation uses classical histological techniques as well as immunohistochemistry to characterize cellular clusters and neuropils. This is the first general description of the Neohelice granulata nervous system as a whole at a neuropil and cellular level. Few representations of the central nervous system of Neohelice granulata have been published besides the general scheme published by Bond-Buckup et al., 1991.
