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.
up vote 4 down vote favorite. 1. I know that neurons communicate between each other by filling the junction between dendrites with neurotransmitters. What interests me is if a single neuron only works with one type of neurotransmitter(ex: serotonin), or if it can secrete/receive all of them (serotonin, dopamine, etc).p vote 4 down vote favorite. 1.
