Document Summary
Preview: nerve cells and communication in the brain, the central and peripheral nervous system, hormones and the endocrine system, mapping the brain, nature and nurture. Neurons: the brain"s communicators: specialized in communication with each other. 86 billion neutrons with 160 billion connections: the brain runs on sugar. Neuron components: cell body (soma, dendrites, axon, axon terminals, neurontransmitters (nt, synapse. Glial cells: astrocytes star shaped, oligodendrocytes. Neurotranmission: the communication between neurons is chemical, they bind with receptors sites of the next neuron. 2. most common in the central nervous system associated with learning and technology. Endorphins inhibit the transmission of pain signals produce a feeling of euphoria similar to what is produced by other opioids. Neural plasticity inluence eating, motivation, memory and sleep. Brain-behaviour network sensory information and decision making: central nervous system (cns) the brain and spine, peripheral nervous system (pns) the nerves outside the cns.
