Document Summary

Sigmund freud"s diagram of the manner in which connections established in the system shows component that looks like neurons connecting to one another in a circuit but don"t touch each other. Circuitry like this gives way to psychological cognitive processes. Changes in the connection between neurons are due to experiences ex. Cell body (soma) contains a number of structures that is the control system of the neuron (releases energy, contains the nucleus dna) Dendrites receive information from other neurons, then travels down to the cell body, (axon hillock) final decision maker whether or not the neuron will send the signal. Axon hillock cone shaped region at the junction between the axon and cell body. Nodes of ranvier the gaps between sections of myelin. Terminal buttons the buttonlike endings of the axon branches which release chemicals into synapses. Receives thousands of inputs but has to decide what to output.
