The brain is like a holiday dinner table, where family is gathered around and actions and interactions abound. The brain constantly working, with different parts performing different tasks to allow the human to function. Likewise, the no holiday dinner would be complete without its different parts.
Like the cellphones that everyone has used, the neurons have made this whole thing possible. Neurons are the “building blocks” of the brain, just like cell phones are now a staple in building a great Thanksgiving dinner- the hostess might use hers to look up the perfect gravy recipe while the extended family might use theirs to navigate to the hostesses’ home. Like cellphones, neurons are also used to send messages- just like we do on thanksgiving: “where are you? Dinner’s at 1!”

Like a dinner table, the corpus callosum connects the different hemispheres and allows them to communicate with each other. The hostess may be likened with the motor cortex, which generates neural impulses that control the execution of movements. Like the motor cortex, the hostess gives directions and coordinates the movements of guests to ensure a great meal.
The occipital lobe is similar to the uncle who can’t put down his camera- the occipital lobe is responsible with processing in the visual information.
In the corner, you might find the great-aunt who can’t hold back the tears. This holiday dinner has brought back the memories of past dinners, where her husband joined them before he passed away. Likewise, the amygdala helps with emotions and memories.
The grandfather who tells stories of long ago over dinner is like the hippocampus, which is mainly associated with long-term memory.
Like the grandmother who just sits back and smiles as she simply processes all the conversations that she hears, the sounds of laughter and dishes clanking, the auditory cortex processes auditory
The brain is an organ that regulates body functions, behaviors, and emotions. Neurons are the cells that fulfill these functions. How do neurons do this? A neuron plays an important role in the central nervous system. Why? Because neurons regulate how we think, feel, and control our body functions. A typical neuron has three parts: cell body, axon, and dendrites. When a neuron receives an electrical impulse, that impulse travels
messages to the rest of the body. The brain is made up of many different
By contrast, our thinking (neocortex) human coping brain has the ability to learn and use language. These functions require the linking of learning brain cells we call neurons. These microscopic, multi-functional neurons are building blocks not only for thinking and learning, but for deciding the way we behave. Thinking brain makes possible our organizing and planning abilities. It also enables us to figure out the meaning of our emotional experiences, such as why we are upset or hurt. The meanings of emotional experiences are what we call our
The amygdala is located in the brain’s temporal lobe and enables us to feel certain emotions. It is our emotions that make us human and it helps in connecting us with one another. One of the most important emotions that the amygdala is responsible for is our fear response. Flight-or-fight is crucial for the survival of any living being, i.e. when an animal feels cornered and threatened, their body will respond by preparing them to flee, if able, or attack.
The brain is part of the central nervous system, which consists of neurons and glia. Neurons which are the excitable nerve cells of the nervous system that conduct electrical impulses, or signals, that serve as communication between the brain, sensory receptors, muscles, and spinal cord. In order to achieve rapid communication over a long distance, neurons have developed a special ability for sending electrical signals, called action potentials, along axons. The way in which the cell body of a neuron communicates with its own terminals via the axon is called conduction. In order for conduction to occur, an action potential which is an electrical signal that occurs in a neuron due to ions moving across the neuronal membrane which results in depolarization of a neuron, is to be generated near the cell body area of the axon.

The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one

Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system.
The brain has four major lobes. The frontal lobe, the parietal lobe, the occipital lobe, and temporal lobe are responsible for all of the activities of the body, from seeing, hearing, tasting, to touching, moving, and even memory. After many years of debating, scientist presents what they called the localization issue, Garret explains how Fritsch and Hitzig studied dog with conforming observations, but the cases of Phineas Gage’s accident in 1848 and Paul Broca’s autopsy of a man brain in 1861 really grabbed the attention of an enthusiastic scientific community (Garret 2015 p.6)

The brain is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think.
The neuron plays an important role in the occupation of the brain (Rollin Koscis). A neuron is...
The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place.
