How is the brain adapted to its functions?

Answer 1

Via and through hundreds of thousands of years of doing just that, adapting functions to suit conditions.

Answer 2

1) No one knows, thousands are trying to find out.

2) At a dumb level, each neuron acts as a switch with one output but (almost always) multiple inputs.

3) At its simplest it might be binary (like a computer), but the multiple inputs allow it to act as an analog device.

4) We're pretty sure that it's NOT a single computing device, but a whole slew of independent computers. (With some kind of a program telling itself that its all one thing.)

5) The synapses (the switches of the circuitry) can be (and are) modified by what you're 'thinking' ... thus the brain is a never fixed thing, it's always changing.

6) Think of the brain as the 'hardware' and the mind as the 'software'.

Answer 3

The brain performs many functions. The most important functions are in the brain stem, this contains the cardiac and respiratory centers that keep us alive.

Also one of the major function of the brain is to FORGET!

hehehehehehe

Answer 4

Our brain cells needs o2 to survive. if the cells don't have the optimum levels of o2 they will die, if they die our body will start to fail and many of our organs will fail to get all the o2 and other needs, such as our blood pressure will rise and as a result of high blood pressure we could possibly have a stroke or a bleed of the Brain.

Answer 5

The brain is composed of neurons and glial cells; the neurons are a type of data processing cell, and the glial cells are a support mechanism that helps to hold the neurons in the correct position and to regulate the chemical environment of the brain. Each neuron has many dendrites which connect it to other neurons or to sensory organs or to muscles in the body (longer distance connections require axons rather than dendrites, but it's the same thing, just a connecting fiber). A neuron can do one of two things: it can fire or not fire. By firing, I mean sending out an electrochemical signal along dendrites or axons. The combination of all the messages that are received by a neuron is what determines whether a neuron fires or not. There is an added complication, that for a neuron signal to pass from one set of dendrites to another, though the place where they meet (which is called a synapse) there also has to be enough neurotransmitters (dopamine, serotonin etc.) in the synapse. The brain as a whole, with its very large numbers of neurons and their very complex interconnections, can then do the data processing necessary to control the body.

Answer 6

it control the left and right of your brain! because it just control the left and right of your brain!

Answer 7

It does it all in the Cerebrum. All the organs help, though.

Answer 8

The communication between the various nervous systems are done through neurotransmitters.

Answer 9
