Document Summary
3. 2) pg. 75) how the nervous system works: cells and neurotransmitters. The venom of the taipan snake is neurotoxic; it specifically attacks cells of the nervous system. Psychologists are most interested in neurons; a major cell in the nervous system that send and receive messages. The main purpose neuron is to fire, receive input from one group of neurons and parts of the cell that transits information, and then to transmit that information to other neurons. This allows neurons to work together as parts of networks. This eventually leads to forms of behaviour. Neurons have a cell body/soma; contains the nucleus in the neuron. Input is received by dendrites; small branches radiating from the cell body that receive messages from other cells and transmit those messages to the rest of the cell. Neurons receive inputs from other neurons and these impulses from other cells travel across the neuron to the axon hillock.
