Question

Medal & Fan !! :D
How does the Brain work ?

Answer 1

well that is a generalized question. what u asking for?endocrine control? neuron control?

Answer 2

That's a question with a very detailed answer...but to give a very basic overview, the brain is part of the central nervous system and consists of a huge network of specialized cells called neurons. The brain is responsible for a vast number of things including coordinating breathing and heartbeat, sensing pain, hunger, thirst, temperature, and more, producing hormones, producing and storing memory, and producing speech. Without the brain, we would be unable to see, hear, feel, smell, or taste. We would not have feelings or emotions, or be able to think, create, or reason.

Individual neurons are composed of 3 main parts: dendrites, the cell body or soma, and axons. Dendrites and axons are both projections from the soma, but the difference is that dendrites receive information from other neurons, while axons send information to other neurons. Also, a neuron can have hundreds of dendrites, but it has only one axon. The soma is where the nucleus and most organelles of the neurons are located.

Action potentials, which are essentially organized electrical signals that neurons use to send information, begin at the point where the soma meets the axon. Action potentials travel down the axon to the target neuron. When they reach the end of the axon (the axon terminal), a series of subcellular activities occur that results in the release of neurotransmitters, chemical messengers that diffuse from the active neuron to other neurons it communicates with. Neurotransmitters interact with receptors on target neurons to produce effects such as excitation or inhibition of that neuron. The axon of one neuron interacts with the dendrites of another neuron in an area known as the synapse. The neurotransmitters diffuse through the "empty space" in the synapse, known as the synaptic cleft.

All the brain functions I mentioned earlier occur as the result of the coordinated firing of hundreds to thousands to millions of neurons in different areas of the brain to produce thoughts, behaviours, and everything else that makes you...you!

To say this summary scratches the surface would be generous, but hopefully that gives you a starting point. If you want to know anything else please let me know!
