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.
Making the world better, one answer at a time. Neurotransmitters are the chemical medium through which the signals move from one neuron to the next at the synapses. This is called neurotransmission and the way it is done is through electrochemical processes.
