PSYC62H3 Chapter Notes - Chapter 2: Lateral Corticospinal Tract, Autonomic Nervous System, Basal Forebrain
Document Summary
Neurons cells in the ns that receive and transmit information to other neurons: serve important role for behaviour. Glia cells cells that support the function of neurons. 100 billion neurons but 10 times as many glial cells. Dendritic spines grow along length of dendritic branches; membranes of dendrites and dendritic spines contain receptors; activated by nt cause change in functioning of neuron. Receptive area - overall coverage of dendrites, more dendrites = more input it can receive from other neurons: axon part of a neuron that sends nts to other neurons. Usually only one, branches from soma, opposite from dendrites. Interneuron neuron with the soma and axon found within the same structure: afferent neuron has axon going to another structure. Sensory neurons neuron that conveys sensory information via axons to the cns: efferent neuron has axon coming from a structure.
