Document Summary

The biological basis of behavior: overview of the nervous system. Synapse (all signals stop at the end of each axon) (traffic cop). The neuron: the synapse, neurotransmitters, acetylcholine, norepinephrine, dopamine, serotonin, gamma-aminobutyric acid (gaba, neuromodulators. Natural opioids (endorphins: imaging techniques, cat or ct, pet, mri and fmri, lesions, stimulation, recording. They would produce lesions in the parts of the brain in the cat and see if stimulation would affect the movement. Recording signals when cells are firing and it is not. In humans, there were cases of naturally occurring lesions. In the modern age, individuals can obtain an mri. Yet animals, still must be either trained or have artificial lesions: eeg a) this was a line graph displaying brain waves. Whereas, today it displays almost as a 3d imaging: overview of brain, cerebral cortex, cerebrum, neocortex, new brain. All of us have a reptilian brain, and a mammalian brain.
