Document Summary

Chapter 3: biological psychology (part 1: nerve cells (pp. Behaviours depend on rapid info processing (eye-brain, brain-hand, hand-brain) Nervous system handles information, just as the circulatory system handles blood. Receive and transmission of info is an electrochemical process. Info travels electrically from one point to another within a neuron. Pos. spike in polarity followed by sudden decrease(more neg. than start) 3. 4! dendrites-branch like fibres that receive information from other neurons axon- tail-like part of a neuron that sends information to other neurons soma action potential. As long as the threshold is reached in the cell body, the signal will travel down the axon. Located at the end of the axon. Synapse: where the terminal buttons meet the dendrites of another neurn(don"t touch) Arrival of an actn ptnl at the terminal buttns trigger release of neurotransmitters. Chemicals that transmit info from one neuron to another. Some neurotransmitters bind to receptors in the post synaptic neuron.
