Fora PubMed search using the term "brain" shows that 87, papers were published. What are some of the methods and techniques used by neuroscientists? A neuron is a nerve cell. The brain is made up of approximately billion neurons. Neurons are similar to other cells in the body in some ways such as: Neurons are surrounded by a membrane.

Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other "organelles". However, neurons differ from other cells in the body in some ways such as: Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from thecell body. Neurons communicate with each other through an electrochemical process.
Neurons form specialized connections called "synapses" and produce special chemicals called "neurotransmitters" that are released at the synapse. The Hows How big is the brain? How much does the brain weigh? To get an idea of how many billion is, think of this: Here is another way to think of billion: To get an idea of how small a neuron is, let's do some more math: How long is a neuron?
How big is the brain compared to the rest of the body?
Perhaps, the best way to describe what neuroscientists study is to list the "levels" at which experiments can be done: In other words, what causes people and animals to do the things they do. This could also include investigations of what parts of the brain are connected to other parts. First, you have to finish high school Second, you get a university degree Third, you go to either graduate school for a Ph.

Anatomically speaking, the nervous system is comprised of the central nervous system the brain and the spinal cord, which are the interpretation and command centersand the peripheral nervous system, which is composed of the nerves the transmission network.
Functionally speaking, the nervous system is comprised of the somatic nervous system and the autonomic nervous system.
The somatic nervous system, or voluntary system, makes it possible for the body to interact with its environment. It acts only on the skeletal muscles and governs voluntary movements, reflexes and semiautomatic movements maintaining balance, posture, walking as well as receives the sensory messages from the skin and the sensory organs.
The autonomic nervous system regulates unconscious visceral functions: It acts on the smooth muscles which enable the involuntary movements of the organscertain glands, the vascular system and the heart muscle.
In the nervous system, information is carried in the form of electrical and chemical signals by highly complex cells called neurons. The human body contains some billion neurons, which form a part of the nervous tissue the brain, the spinal cord and the nerves.
