Synaptic plasticity as a cortical coding scheme.

abstract：:Iterated learning describes the process whereby an individual learns their behaviour by exposure to another individual's behaviour, who themselves learnt it in the same way. It can be seen as a key mechanism of cultural evolution. We review various methods for understanding how behaviour is shaped by the iterated lear...

abstract：:Ca2+ entry into neurons is one of the major effectors of stimulus-induced physiological change. Ca2+ can enter neurons through a number of different voltage-gated and ligand-gated channels. Depending on the route of entry, Ca2+ stimulates distinct intracellular signaling pathways, which activate different sets of gene...
