We further extended these findings by looking at two mechanisms for controlling the repression of gene ...

It has been argued that FEF neurons indicate the locations of behaviorally significant visual stimuli and are not inherently sensitive to specific features of the visual stimuli per se. Here, for the first time, we directly ...

Crayfish motor neurons seem to repair damage to peripheral axons by selective fusion of outgrowing proximal slumps with severed distal processes that can survive morphologically and physiologically intact for over 200 days. Survival of isolated motor and CNS giant axons is associated with ...
