Document Summary
Delgado went on to prove that electrical stimulation to certain areas of the brain elicited certain responses from individuals, including changes in mood or behavior. Neurons normally use electrical signals to sum up vast amounts of information. Neurophysiology: the study of the specialized life processes that allow neurons to use chemical and electrical processes to sum up vast amounts of information, and then pass information on to other neurons. The classic pattern of neural function: information flows within a neuron via electrical signals (action potentials) and passes between neurons through chemical signals (neurotransmitters). Electrical signals are the vocabulary of the nervous. All living cells are more negative on the inside than on the outside, so we say that they are polarized: there is a difference in electrical charge between the inside and outside of the cell. A balance of electrochemical forces produces the resting potential. Anion: a negatively charged ion, such as a protein or chloride ion.
