Structure of the Neuron Chemical signals (i.e., neurotransmitters) are released from terminals Nerve impulses (i.e., action potentials) move along the axon Fig. 1.2.1

Two Neurons(including synapse, the point of functional connection between them) SYNAPSE (magnified view of synapse) Fig. 1.2.2

CNS and PNS(including sensory, motor and autonomic components of PNS) Fig. 1.2.3

Lesion Method-study of the behavioral effects of damage to the nervous system Fig. 1.3.1

Recording of the Electrical Activity of the Nervous System: EEGElectrical activity is recorded from the surface of the skull; “brain waves” represent electrical changes over time Fig. 1.3.2

Single Neuron Recording Also known as “single unit” recording. As a rat moves through a maze, activity of “place cells” can be recorded in a brain area known as the hippocampus. Action Potentials Fig. 1.3.3

Microdialysis Methods(allows for measurement of chemical activity in the brain) Fig. 1.3.4

CT or CAT Scan of the Brain Fig. 1.3.5

MRI Methods Fig. 1.3.6

fMRI Methods A brain area known as the amygdala is activated by fear. Fig. 1.3.7
