Cell type diversification and circuit integration in the hatchling octopus brain KU Leuven
Cephalopods, such as octopus, squid and cuttlefish, are mollusks. Unlike other mollusks, which have fairly simple nervous systems, cephalopods evolved large and centralized nervous systems. The nervous system of the octopus has a similar number of nerve cells as a small primate and its anatomical complexity parallels vertebrate brains. How octopuses have evolved such a large and complex brain independently is not yet known. Moreover, the ...
