In a review of available evidence on motor and cognitive processes, four conclusions were described by Diamond (2000). First, neuroimaging studies frequently point out that tasks that activate the prefrontal cortex, an area of the brain associated with attention, also activate areas of the brain necessary to motor processing, specifically the cerebellum. Second, damage to certain areas of the prefrontal cortex or cerebellum often results in a reduction of activity in parts of the other area (i.e

structure, natural or artificial, on earth.” Tim Green, Stephen F. Heinemann and Jim F. Gusella (from a paper in Neuron, 1998) Slide 3 Brain development. Slide 4 What we know about human brain? The human brain is the most complex of all biological systems. It is made of a hundred billion information processing cells called neurons. The neurons communicated with each other by making connections. This connections called synapses. It is estimated there are 60 trillion connections in the adult brain. It

Neural Plasticity Paper 1 Neural Plasticity Paper Functions and Limitations of Neural Plasticity Research today has shown that “the capacity of the human brain for functional and structural reorganization throughout life is now well recognized.” (V. Valkanova, R. E. Rodriguez, K. P. Ebmeier. 2014) Neural Plasticity is what we understand as the brains ability to adapted to and

Aspartate and glutamate act as neurotransmitters in the brain by facilitating the transmission of information from neuron to neuron. Too much aspartate or glutamate in the brain kills certain neurons by allowing the influx of too much calcium into the cells. This influx triggers excessive amounts of free radicals, which kill the cells. The neural cell damage that can be caused by excessive aspartate and glutamate is why they are referred to as "excitotoxins." They "excite" or stimulate the neural

Alzheimer’s disease was discovered in 1906 by Dr. Alois Alzheimer. Dr. Alzheimer was studying the brain of a woman who had recently died of an illness that was undetermined. He noticed that the tissue of the brain he had been studying had changed over time. The symptoms of this disease at the time was memory loss, unpredictable actions, and language problems (Alz.org). Alzheimer’s disease is a disease that consists of plaques and tangles grown on the brain, this causes memory loss. Alzheimer’s

Alzheimer’s disease: Causes & Symptoms Alzheimer's disease is the most common reason of dementia. Dementia describes memory loss and complications with thinking, problem solving. These occur mainly due to damage of brain cells by certain diseases, which includes Alzheimer's disease. It slowly ends a person’s ability to learn, make judgements, communication and regular activities. Initially, proteins build up in the brain to form structures known as plaques and tangles, which leads to the loss

Bell’s palsy is the paralysis of the muscles usually occurring on one side of the face (although it can happen on both sides of the face). It occurs when the 7th cranial nerve that connects to the muscles of the face fails to function properly, causing the facial muscles to weaken or become paralyzed. The main cause of Bell’s palsy is unknown, but it may caused by autoimmune disorders or viral infections. The believed causes of this disease are herpes simplex virus and shingles. Other viral diseases

Here’s the technical aspect: The brain actually calls for certain foods whether sweet, salty, sour or laden with caffeine. There is a reward system within our brain, which was designed to “reward” us when we do things that support our survival. This includes behaviors such as eating, exercising and sex for example. Your brain reacts when we eat by releasing a chemical known as dopamine. The Dopamine is transmitted as a pleasurable experience, and your brain is hardwired to pursue the pleasurable

Although the cause of Alzheimer’s disease isn’t completely understood, two major factors that are connected to the progression are plaques and tangles. In the cell membrane of a neuron in the brain, you have an molecule called amyloid precursor protein, or APP. One end of the amyloid is in the cell, while the other is out. Scientists believe that this helps the neuron grow and repair itself after an injury. Since APP is a protein, it gets used and over time gets broken down and recycled. Normally

The Brain The brain is known to be the most complex part of the human body. It weighs around three-pounds and is where the intelligence, senses (smell, touch, sight, hearing, and touch), initiator of body movement, and behavior is processed. For centuries, the brain has been examined and researched, but nobody really knew how it worked, not until the last 10 years. The last 10 years, scientists and researchers have learned more about the brain than the past centuries of brain research. This is
