Fig1.5. shows a broad overview of the cerebral cortex. Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise
The human brain consists on the left cerebral hemisphere and the right cerebral hemisphere, which signifies the control of the four lobes and its functions. The left cerebral hemisphere is an important section of the brain with the usage of speech, reading, and writing skills. The right cerebral hemisphere is also an important section as to the development of understanding, paying attention, and expressing emotions. Then within each cerebral hemisphere are four major areas call the Frontal, Parietal
Dura mater – the substance that covers the brain and the spinal cord • Endosteal layer – resembles the periosteum of bones, provides blood vessels • Meningeal layer – dense, fibrous membrane • Falx cerebri – a large crescent shaped fold that is amid cerebral hemispheres • Tentorium cerebelli – horizontal large crescent crease attached to the internal surface of the occipital bone • Falx cerebelli - a fold that divides the cerebellar hemispheres and is attached internally to the occipital bone and is
novel acetylcholinesterase inhibitor, has been shown to dramatically improve cognitive performance in rodents and is currently in clinical trials (N. Greig, Brossi, 1996). Studies of rats with forebrain cholinergic abrasions, known to increase Aβ in cerebral areas of the brain, have shown that Phenserine can protect against this and reduce βAPP production in animals (Haroutunian, 1997). Moreover, the absence of inhibitors of acetylcholinesterase displays a wide range of behavioral deficits in Caenorhabditis
most mysterious. It is the control center of the body and it’s important to understand the complexity of the human brain. Although your brain functions as a whole, it consists of three main parts, The Central Core, the Limbic System, and the Cerebral Cortex. Then those parts break into even smaller parts. The brain is just like the computer, it depends on certain parts to work correctly and get every day jobs and even more complex jobs done. The Central Core The Central Core is the first of the three
cognitive functions. This is why the writer thinks the brain is the most important organ in the human body. The frontal lobe is located right behind the forehead at the top of a human head. The frontal lobe can also be called the “cerebral cortex”. The cerebral cortex is the seat of emotions and judgment related towards sympathy and empathy. It can understand humor, wordplay, and it recognizes sarcasm and irony. (Hartwig, K. L. (2007, May 27)) Motor Cor... ... middle of paper ... ...he brain”

explaining the method in which the axons belonging to the UMN’s lower from the corona radiata and internal capsule to the spinal cord. As these fibers reach the brainstem, Gilman and Newman (2003) explain that they enter the middle section of the cerebral peduncle. While the fibers pass through the base of the pons, the fiber bundles are divided by the pontine nuclei (McCaffrey, 2014). These corticospinal fibers are positioned in a ventral orientation while passing through the brainstem (Gilman and
is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery
1. Acetylcholine: A neurotransmitter that affects our muscle action, our memory, learning, REM (rapid eye movement), sleep, and our emotions. We see Acetylcholine being used when playing a sport. In the peripheral nervous system, Acetylcholine is the neurotransmitter that transmits signals between motor nerves and skeletal muscles. It acts at neuromuscular junctions and allows motor neurons to activate muscle action. For example, the brain might send out a signal to move the left arm. The signal
accompanied by a baring of teeth and facial grimaces. (Nieder, 2014). It simply means that no matter what happens, we can’t control laughter. It’s an involuntary impulse. In fact, it’s a negatively charged electrical impulse traveling through the cerebral cortex. However, I want to know more. What muscles produce the huge smile? What creates the wonderful sound of laughter? Laughter is often involuntary. In fact, it is very difficult to fake it because it requires so many muscles. The main two muscles
The Cerebrum is the largest part of the brain , it controls certain fucntions such as perception, imagination , thought ,judgement and decision making . The surface of the Cerebrum (Cerebral cortex) is comprises of six thin layers of neurons , that rest ontop of a large surface of white matter pathways . The cortex is extemerly twisted and coiled to the point that if it is spread out, it might actually take up as much as 2.5 Square feet, and it comprises of 10 billion neurons and about 50 trillion
The occipital lobe is very important to us, as it takes information from the eyes and processes it. A common name for it is the “visual cortex”. If the occipital lobe is damaged it can cause blindness. Under this is the cerebellum, in charge of very important daily functions like balance and coordination as well as posture. The brain stem is the most basic part of the brain, as well as
surround the brainstem such as the amygdala, hypothalamus, thalamus and hippocampus. These are the main structures, but there are also some minor related areas such as the cingulate gyrus, ventral tegmental area, basal ganglia, and the prefrontal cortex. Function: The limbic system is responsible for many human emotions or drives and particularly those that relate to our basic survival. Some examples would be fear, anger and emotions related to sexual behaviour. It is also involved with feelings

INTRODUCTION The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body. The messages travel in very fine threads called nerves. The nerves and the brain make up a system somewhat like
The Human Memory The reason people exist is because of two important things: memory and language, which have been vital in the evolution of humanity. (Our ancestors needed language to explain how to light a fire to keep them warm and a memory to remember how to do it). So we have a memory because if we did not we would never have evolved far enough for you to ask this question in this place. So how does it work? The process involve in the human memory are very complex… I will present you the
According to the Oxford Dictionary, a dream is “a series of thoughts, images, and sensations occurring in a person’s mind during sleep. Dreams are much more complex than the definition makes them sound. The definition leaves out the how and why the thoughts, images and sensations in dreams occur. There are a great number of theories relating to dreams, but very few questions are answered. There are many ongoing studies relating to dreams. A big question asked about dreams is how they occur
This lobe is also located in the cerebral hemisphere. The parietal lobe focuses on comprehension, language, reading. It also monitors all sensory comprehension. The parietal lobe has two parts. The sensory cortex and motor cortex. The sensory cortex, is located in the front part of the parietal lobe, it receives information from the spinal cord about the different positions of the various
Marijuana, Cannabis Sativa, has been used for centuries for its medicinal and euphorant properties, and its fibers, to make hemp cloth and paper. Medicinally, between 1850 and 1942, it was prescribed in the United States Pharmacopeia as a remedy for a variety of ailments including gout, tetanus, depression, and cramps (Farthing 1992). Today, it is used for reducing intraocular pressure due to glaucoma, as an antiemetic to relieve nausea associated with chemotherapy, and as an appetite stimulant for
