Talk:Brain
From Veritas
The last sentence is the only thing I could "dispute" :)
The mechanic of memory is still a highly unknown area of study in brainwork. Scientists have taken out each portion of the brain individually out of various mice and all of the mice still retained memory, which lead those scientists to theorize that perhaps memory is "stored" by some sort of web of nueron firing throughout the brain or something (I read about it /once/, so I could easily be wrong on something). http://en.wikipedia.org/wiki/Memory#Physiology says something different
Emotions may be triggered by the brain, but physiologically speaking emotions are due to chemicals. (ok, so I've tried finding any links to back up this statement, and it seems noone is really clear on what causes emotions. I've read that emotions are "simply" chemical reactions within the human which cause certain changes in the brain and body to occur, but without other (credible) people to back that up I could be wrong.)

- The brain is a neural network, and as such, every thought exists as a fairly well-distributed activation state. Thus, memory of most things are well-distributed throughout the brain in the "pattern" of neuron firings, rather than being filed in specific neurons. Areas like the hippocampus are considered related to the process of memory storage and memory retrieval, but the precise mechanism for that is not fully understood. Kobok 11:49, 8 Aug 2005 (PDT)
- Emotions are a subjective description of a mental state combined with a bodily chemical state. The chemical state is partly mediated by the endocrine system, which is both in the brain and distributed out of the body, but in most cases receives its signalling from the brain. For example, the adrenal glands don't know to make you afraid or alarmed unless the brain signals to them that it has detected danger. Kobok 11:49, 8 Aug 2005 (PDT)
- Perhaps you can use that information to make the last sentence more comfortable to you. Kobok 11:49, 8 Aug 2005 (PDT)
