Document Summary
Soma, dendrites, axon/myelin sheath, terminals, and neurotransmitters (nts) Controls environment inside & outside of the cell: some molecules flow freely into and out of the cell, some only come in through protein channels in the membrane. Action potential steps (figure 2. 8 & page 31) Local potential v. action potential: graded v. all-or-none, decremental v. nondecremental. Refractory periods: absolute v. relative refractory periods, rate law. Decrease energy stored in the cell=increase transmission speed. Increase in complexity of the brain (they support all of our neurons!) Chapter 2 outline: communication within the nervous system. Garrett"s brain & behavior: an introduction to biological psychology. Creates graded local potentials which create action potentials. Combines potentials from all of those connections: spatial summation, temporal summation. Drugs that use those to work: regulative synaptic activity. Sense nts in cleft & alters presynaptic output. Change # & sensitivity in response to nts.
