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.
Neurotransmitters are molecules that nerve cells, or neurons, use to communicate. When electrically stimulated, the transmitting, or prensynatptic, neuron releases neurotransmitters into the gap, called a synapse, between itself and an adjacent neuron.hey are distinguished from inhibitory neurotransmitters, which make an action potential in the cell less likely. The most common excitatory neurotransmitter in all vertebrates, including human beings, is called glutamate.
