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.
Electrical signals carry information within a single neuron. Communication between neurons (with a few exceptions in mammals) is a chemical process. When the neuron is stimulated, the electrical signal (action potential) travels down the axon to the axon terminals.ommunication between neurons is the foundation for brain function. Understanding how neurotransmission occurs is crucial to understanding how the brain processes and integrates information. Interruption of neural communication causes changes in cognitive processes and behavior.
