How does the brain know where to send electric messages?

Question

I was reading in my psychology book, which said that you could send electricity through the brain at certain locations to stimulate various emotions, such as fear, anger, or hopelessness, or direct someone's body. How, though, is the electricity directed by the neurons? Does the body consist of pre-defined paths or links of neurons? If so, would the result be consistent every time in the same location? That would really back up my hypothesis that psychology is extremely mathematical.

Answer 1

I believe you're right that psychology is very mathematical.

The central nervous system is all wired up and (when its healthy and normal) ready to send messages when the human being is formed. The ability of it to send messages, though, can be affected by neuropeptides. ("chemicals" for lack of a better term) A psychologist to whom I brought a child for an educational evaluation once said that some messages are not correctly transmitted because (as he said) it is believed that some coating may not present.

I believe there is one formula (I'm not going to say it on here for my own reasons) that explains exactly how and why brains develop and how and why electrical connections are made or not made; because, as you know, it is entirely possible for electrical connections to not function or not develop for one reason or another.

Depending on (for lack of a more scientific way to describe it briefly) "the blend of chemicals going on", it is possible that there would not necessarily have to be consistency every time in every location.

It is possible (with equipment today) for doctors/scientists to see what part of a brain is "lighting up" during certain activites. They also have a solid understanding of what part of the brain governs what activities. When they stimulate emotions they are artificially stimulating them. Just the other night, there was a woman who had had a procedure that would allow a doctor to change her emotions artifically and separately from what was really going on around her.

As far as I know, if it were at all possible to, say, watch what happens in a brain when a child, say, is being abused, and to watch it for the time the brain was developing; it would probably show the physiological changes in the brain that, maybe, would cause either alterations in the brain itself or else changes in the "chemicals" or both. In other words, I believe you're probably right (although, again, I don't necessarily know anything) about the mathematical part.

I do think, though, that some more superficial issues of psychology may be less math and more art; or else, maybe its more a matter of the same formula at work on a different and less deep level.

Again (and I can't say it enough) I don't know anything.....

Kepler, a noted Nobel Prise for Medicine Winner in the 80's, tells us that brain cells are hard wired to their signal receptors from birth.

Answer 4

I don't think that's right. I think it may be links of neurons or cells.

Could be,,I would think that most of the neurological system is "hard wired" in normal folks. Kind of the"I think, therefore I am kind of logic,,:-)=
