The purpose of this report is to describe the function and overall purpose of the brain, and compare it to current technologies that aim to replace or mimic it. The human brain is a complex organ that is still being heavily studied. Research has shown that many functions and components are still misunderstood by scientists, but the overall function is well documented.
Function
The brain is located in the skull and is the center of communication for the human nervous system. Its purpose is to process all the information given to it by other organs and determine what actions should be taken. Many of these calculations are done autonomously with no conscious decision making. The brain also holds memories and can react instinctively to stimuli. Human brains differ from other animals due to their

Neurons are electrically excitable cells that transport electrical and chemical signals throughout the brain. The 80-100 billion neurons form neural networks when connected together which allow signals to propagate along complex pathways. Glial cells are non-neuronal cells that maintain the brain through many different functions including: supplying nutrients, insulating neurons, and destroying pathogens.
The processes performed by the brain can be centralized to four main lobes: frontal, parietal, occipital, and temporal. Reasoning, planning, speech, emotions, and problem solving are mainly performed in the frontal lobe. Movement, orientation, recognition, and perception are processed in the parietal lobe. Visual processing is associated with the occipital lobe. Perception and recognition of auditory stimuli, memory, and speech are performed by the temporal lobe.
Humans possess a conscious, which is a trait that is arguably unique in the animal kingdom. Currently, no concrete evidence has proven other animals have any sort of self-awareness. Consciousness allows for self-awareness and increased
| Neurons are:1. highly specialized cells that produce myelin.2. highly specialized cells that receive and transmit information from one area of the body to another.3. found only in the spinal cord and bone marrow.4. found in primates and humans, but not in other animals.
Let’s begin by discussing the parts and function of our brains. The neo cortex is the largest part of the brain and the most important. This part of the brain is divided into four different sections: the temporal lobe, occipital lobe, parietal and the frontal lobe. These four sections are located on either the right or left hemisphere of the brain they are connected by axons that send messages to and fro between both hemispheres and to specific parts of the brain then to the body. Our neo cortex is what makes us so different from our primate cousins.
Our brain is separated into several regions that undergo different kind of information. Then there are regions that process information such as visual, verbal communication, auditory, emotions, etc. These different regions communicate with each other and each one of them has its own processes it has to complete first. For example one looks at a piece of art and express their emotions with language, thus working the verbal function part of the brain.
Their principal function is to interpret and relay electrochemical signals throughout the nervous system. Like all cells, they possess a cell body called the soma. However, they distinguish themselves from other cells by their complex structures and shapes. Most neurons in the CNS are classified as multipolar (OpenStax College, 2013). This classification arises from their multiple dendrites and single
The human brain is an amazing device. It controls everything we do. It controls our bodies, how we communicate, how we function. Our brains our
The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions, such as the ability to speak, and see amongst us. This brain is made up of simple mater (Pia mater, Arachnoid mater, Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ, the brain, unless you’re a medical student of course! Despite that people go on with their daily activities using the human natural senses. Looking at the world through the eyes, watching for any danger around us; ears for hearing the sounds detecting something that may call for danger, the
It made up of more than 100 billion nerves that communicate in trillions of connections called synapses. There are specialized areas that work together to make up the brain. The outermost layer of brain cells called the cortex is where thinking and voluntary movements begin. The brain stem is between the spinal cord and the rest of the brain and controls basic functions like breathing and sleep. The part that is responsible for balance is known as the cerebellum. Additionally, the brain is divided into five lobes: the frontal lobe, parietal lobe, temporal lobe, occipital lobe, and insula. The frontal lobe is responsible for problem solving, planning, speech, movement, judgment and motor function. The parietal lobe manages sensation, temperature, touch, body position, and handwriting. The temporal lobe is involved with memory and hearing. The occipital lobe contains the brain’s visual processing system. The insula is responsible for memory, taste, and integration of information from the other four lobes. There a layer of tissue called the meninges which surrounds the brain and the skull (cranium) to protect the brain from
Before reading this article I thought we knew a lot about how the brain functions. I have a new understanding that we understand very little about how the brain really works.
The primary structure in the cranial cavity is the brain which has a mass around 1300 grams and make up by approximately 100 billion neurons and 10 to 50 trillion neuroglia in adults (Tortora and Derrickson, 2011). The weight of the brain increases rapidly during the first four years of life and reaches the maximum weight around twentieth years (Gallucci et al., 2005). The brain is the portion of central nervous system that act as control center for registering sensation correlated with one another and with stored information, decision making, and actions. Furthermore, it also acts as a center for the intellectual, emotions, behavior and memories (Tortora and Derrickson, 2011).
This can also be seen in detail in brain tissue. The white matter consists of axon and Oligodendrocytes. while the gray matter consists of neuron and unmylinated fibers .Both tissue have more white matter .This refer to us supporting cell of CNS. The brain is a major functional unit of the central nervous system.

The glial cells are the support cells of you brain and help support the sending of signals between you nerve cells. They also have several different variants that have a variety of different jobs including removing cellular debris after an injury, keeping a good chemical environment, and speeding up the process of the passing of information.
The brain is the most important part of the body, it controls everything we do. It is one of the most complex organs of the body. It has many parts, including these main bits: The cortex is the outer layer of the brain and it controls thinking and movement. The brain stem/spinal cord is between the spine and the rest of the brain and the controls our sleep and breathing. The cerebellum is in the middle and back of the brain and controls balance and coordination. There are also several lobes which are important to the brain as well. The frontal lobe is responsible for problem solving and judgement and the temporal lobe is responsible for memory and hearing. The parietal lobe is responsible for processing sensory information from
The brain is an important organ in the human body. Although, the brain is an intricate structure, it influences everything, as our thoughts, our actions, and our emotions. Gaining knowledge on the functions of the brain can aid us in understanding human behavior as to why they behave in the manner they do.
The frontal lobes which as its name indicates are located in the front of the brain's cortex and is responsible for the most complex and tasking functions of the brain. The frontal lobes contain several parts compared to the other lobes in the cortex which includes the prefrontal cortex, medial prefrontal cortex, and the orbitofrontal prefrontal cortex, all of which have a strong relationship with the limbic system according to ciccarelli and white (2010). The functions of the frontal lobes are mostly dedicated to complex decision making, storing and accessing memories and also affects personality, language, and making
The four lobes that contribute is the frontal lobe, temporal lobe, occipital lobe, and the parietal lobe. The frontal lobe controls problem solving, planning, and decision making. One of the jobs of cognitive functioning is the reasoning. Problem solving is part of thinking and shows the brain plays that role in a cognitive function. The temporal lobe auditory perception, speech, memory, and emotional responses. The occipital lobe has the jobs of color recognition and visual perception. Lastly, the parietal lobe takes care of the sensory information and language. All the nodes play a part of the cognitive function. There are more structures of the brain that play a role in cognitive function. These structures are the thalamus, putamen, cerebellum, caudate, hippocampus, and amygdala (Leismen, Moustafa, & Shafir,
