This is connected to the limbic system, which controls drives and emotions as well as human involuntary behavior that is crucial for survival, for instance, affection, docility, sexual feelings, anger, fear, pleasure, and pain. The limbic system is also responsible for smell senses in animals triggered by nerves from the olfactory bulb. The limbic system is fed by the hypothalamus, thalamus, and the amygdala, the small almond-shaped nerve cells complex that is responsible for the reception of input from the cerebral cortex and the olfactory system. The limbic system is thought to be indirectly stimulated by brain’s electric discharge thereby setting off seizures.
Hippocampus
The hippocampus, which is shaped like a sea horse, forms a major part of the limbic system and is situated at the base of the temporal lobe adjacent to the sets of the association fibers. They form the nerve fiber bundles connecting both regions of the cerebral cortex to allow for information exchange between the entire cerebral cortex, limbic system, and the hippocampus. The long-term memory of a human being is stored throughout the cerebral cortex.

As such, the neuron relays signals through an axon, which extends outwards like a single long arm from the soma, or the body of the cell. The neurons contain numerous shorter arms called the dendrites, which send signals back to the soma. The axon’s ability is enhanced by the surrounding myelin sheath. The myelin sheath is the natural insulator protecting the axon from nearby nerve impulse interference. The speed of the electrical impulses can reach a high of 120 meters per second. The site of the communication is referred to as synapse and includes the dendrite and the button. There is also an electrical synapse, where the cell membrane of two neurons is linked by molecules of tubular
