The politics of identity is a kind of cultural politics. It relies on the development of a culture that is able to create new and affirmative conceptions of the self, to articulate collective identities, and to forge a sense of group loyalty.
Neurons transmit electrical impulses by allowing the passage of charged ions across their membranes in response to stimuli, changing the charge of the neuron in a process that propagates through the axon of the neuron. Normally, neurons maintain an internal negative charge relative to their environment by excluding sodium ions from their cytoplasm.
Synaptic Transmission. Communication between nerve cells occurs by the propagation of an action potential by one neuron down its axon and into the synaptic terminal where chemical neurotransmitters are released into the synaptic cleft. These neurotransmitters diffuse across the cleft and bind to receptors on target neurons.
