Two-Step Wiring Plasticity – A mechanism for estrogen-induced rewiring of cortical circuits
چکیده انگلیسی

Estrogens have been shown to exert powerful effects on cognitive behaviors mediated by several areas of the brain including the cortex. Remodeling of spiny synapses is a key step in the rewiring of neuronal circuitry thought to underlie the processing and storage of information in the forebrain. Whereas estrogen has been shown to regulate synapse structure and function, we are only just starting to understand the molecular and cellular underpinnings of how estrogens can modulate neuronal circuits. Here I will review recent molecular and cellular work that offers a potential mechanism of how estrogen may modulate synapse structure and function of cortical neurons. This mechanism allows cortical neurons to respond to activity-dependent stimuli with greater efficacy in a cellular model termed “Two-Step Wiring Plasticity”. This novel form of spine plasticity thus provides insight into how estrogens may modulate the rewiring of neuronal circuits, underlying its ability to influencing cortically based behaviors.This article is part of a Special Issue entitled ‘Neurosteroids’.
