Quotes About Dendritic

Knowledge emerged about synapses, neurotransmitter-ology was born, and this idea was modified—a new memory requires the formation of a new synapse, a new connection between an axon terminal and a dendritic spine.

Remarkably, the size of neurons' dendritic trees in the hippocampus expands and contracts like an accordion throughout a female rat's ovulatory cycle, with the size (and her cognitive skills) peaking when estrogen peaks.fn6 Thus, neurons can form new dendritic branches and spines, increasing the size of their dendritic tree or, in other circumstances, do the opposite; hormones frequently mediate these effects.

We might even have to hunt for the NCC down at the subcellular level, seeking mechanisms operating inside cells rather than across large neural coalitions, as is widely assumed. Indeed, some have hypothesized, as a possible NCC, all-or-none electrical events occurring in the dendritic tree of cortical neurons, a sort of handshake confirming that a bottom-up signal has encountered top-down feedback within a certain time window.
