These arms can even initiate a response without consulting the brain. How octopus arms can do all this at a cellular level has largely remained a neuroscience mystery—one that's proven difficult ...

Scientists have demonstrated that cephalopods have an expanded number of microRNA families, which could explain how the complex octopus brain developed. Octopuses and other coleoid cephalopods are ...

A previous study conduced by Hochner had shown that an area in the octopus, brain known to be important for learning and memory, showed a robust, activity-dependent, long-term synaptic ...
