The brain‚ which weighs only three pounds and is made up of eighty percent water‚ is the key organ of our nervous system. It is divided into three different parts: the Cerebrum‚ the Cerebellum‚ and the Medulla Oblongata. The "gray matter" of the brain is about one-eighth inch thick and it gives the brain its gray color. Inside the brain is the cortex‚ which is made up of billions of neurons. These neurons extend into the cerebral hemisphere and it controls all mental activity. In this report I will

Neurotransmitters are chemicals that transmit signals across a synapse‚ a structure that permits to pass electrical or chemical signal to another cell from one neuron to another. Neurotransmitters are synthesized from converting substances that are readily available to the body such as amino acids‚ which are available from food and only need some converting into transmitters. Neurotransmitters crucial to daily life and functions. Scientists are uncertain exactly how many Neurotransmitters there are

The Brain The central core of the human brain‚ often referred to as the “old brain”‚ is the most primitive part of the brain and can be found in all vertebrates dating back more than 500 million years.

If each of the following brain parts individually was damaged‚ what would be the consequence and why? Hippocampus‚ hypothalamus‚ cerebellum‚ reticular formation‚ medulla Hippocampus is important for forming lasting memories. The hippocampus lies inside the temporal lobes‚ which is why stimulating the temporal lobes can produce memory like or dream like experiences. Hippocampus damage can result in anterograde amnesia which is the loss of ability to form new memories. Someone who sustains an

The brain and spinal cord make up the central nervous system and all of the nerves found in our body make up the peripheral nervous
