In the human body the brain is one of the main organs. It helps the body run and work properly. But, what happens if the brain stops working properly? It would affect the whole body. All the systems that the brain is in charge of would stop or not work well. If the brain stopped working properly the central nervous system, the limbic system, and the brain itself can be in danger. The central nervous system is in charge of many of the daily activities that a person does, so what would happen if it is damaged? Someone's whole life can change. Their body can become paralyzed.

The parts of it include the following; Amygdala - almond shaped mass of nuclei involved in emotional responses, hormonal secretions, and memory. The amygdala is responsible for fear conditioning or the associative learning process by which we learn to fear something. Cingulate Gyrus - a fold in the brain involved with sensory input concerning emotions and the regulation of aggressive behavior. Fornix - an arching, fibrous band of nerve fibers that connect the hippocampus to the hypothalamus. Hippocampus - a place where memories are stored Hypothalamus - This structure is very small, about the size of a pearl, it helps you wake up in the morning and all other functions like that. It also helps with emotions as well. Olfactory Cortex, receives sensory information from the olfactory bulb. Thalamus - a large, dual lobed mass of gray matter cells. Certain structures of this system also have to do with memories. Two large limbic system structures, the amygdala and hippocampus. They play a huge role in memories. The amygdala is there for determining what memories are kept and where the memories are kept in the brain.
