The brain consists of four lobes: the frontal, temporal, occipital and parietal. Imagining a line on the top of the head from ear to ear, the portion of the brain at the top of the skull just to the rear of the line is the parietal lobe. In...
Alzheimer's disease is a brain disorder that leads to progressive nerve damage and brain cell death that affects more than 5.3 million Americans, according to the Alzheimer's Association. Alzheimer's is characterized by aggregates of toxic...
According to the National Institute of Neurological Disorders and Stroke (NINDS), the brain is the most complex part of the human body. The brain is responsible for bodily functions and converting sensory information into motor reactions. The...
The cerebrum houses the four major brain regions responsible for higher functioning. According to the Center for Neuro Skills, these four regions include the frontal lobes, parietal lobe, occipital lobe and the temporal lobe. The cerebrum is also...
Driving requires a person to integrate information from multiple visual and auditory sources. Visual information that needs to be processed includes activity on the road, your mirrors and the instrument display. Similarly, auditory information...
The brain is a complex network of structures that work in harmony to control the many vital functions of the body and process information from the internal and outside environment. The vast majority of these functions are reflex actions that occur...
In "The Cognitive Neurosciences III", there are over 1000 pages devoted to explaining the relationship between mind and brain. At the most general level, human cognitive processing occurs in the cortex, the outer layer of the brain composed of...
While the various parts of the brain have been observed to have discreet functions for processing specific types of information, the process of thought, or cognition, uses a neural network of interconnections between separate areas. A region of...
The human brain is an exquisitely complex and highly organized organ. The forebrain, midbrain and hindbrain comprise the three functional regions of the brain. Within each region, individual lobes and structures exist, which control specific...
Alzheimer's disease begins damaging the brain as much as 20 years prior to manifesting any symptoms. Alzheimer's causes neurofibrillary tangles and amyloid plaques to form and develop in various parts of the brain. As Alzheimer's progresses, brain...
The brain is divided vertically from front to back. While appearing like mirror images, there is some functional division between the lobes. These divisions are not absolute. In some people, the functions are reversed from side to side, while in...
The human brain is a complex organ and is responsible for relaying information to the other parts of the body. For example, the brain is involved in memory, thinking, voluntary and involuntary movements. Multiple components make up the human...
The human brain is part of the body’s central nervous system; in conjunction with the spinal cord and nerves, it controls everything that the body does. The main functions of the brain are controlled by three of the brain structures: the...
The brain is a very complex organ where every part is responsible for different activities. So when there is brain damage, normal brain function is affected. The brain is divided into three parts: the cerebrum, the cerebellum and the brain stem....
There are many important parts of the external brain. The surface of the human brain consists of two main parts: the cerebrum and the cerebellum. The cerebrum has many specialized areas that are associated with high-order cognitive functioning...
The central nervous system, which consists of the brain, spinal cord and nerves, controls every function in the body. The brain is divided into three parts: the forebrain, the midbrain and the hindbrain, each of which is further divided into...
Scientists divide the brain into three major parts: the cerebrum, the cerebellum and the brain stem, according to the Mayfield Clinic. They divide the cerebrum into four lobes: the frontal, parietal, temporal and occipital. Subdivisions of these...
The human brain is the computer for the body. It is responsible for every function and movement, from breathing to scratching an itch on the nose. The brain can be labeled based on anatomy or function. In dealing with the anatomy of the brain,...
The human brain contains five major divisions--the cerebral cortex, cerebellum, thalamus, midbrain and brain stem--each with a specific region and function. These regions are interconnected to allow information to travel from one region to...
Each part of the human brain is responsible for functions in the body. The brain is made up of three major sections: the cerebrum, the cerebellum and the brain stem. The cerebrum is divided into two parts, the left hemisphere and the right...
Brain trauma, which involves damage to the brain tissue, affects about 1.7 million people each year, according to the Centers for Disease Control and Prevention (CDC). Damage to the brain can occur even if the injury does not fracture the skull....
Retrograde memory loss, or amnesia, is the loss of memories acquired prior to a brain damage. Retrograde memory loss includes loss of memory of facts and events, also known as "declarative memory," and loss of "how-to" memory, also known as...
Epilepsy, also called seizure disorder, describes a condition of recurrent unprovoked seizures. Seizures occur when nerves on the brain produce a sudden and strong surge of electrical impulses. Unprovoked seizures include those that occur without...
A parietal subdural hematoma, also known as an intracranial hematoma, is a blood clot or hemorrhage in the parietal lobe of your brain. Your parietal lobe is responsible for interpreting signals relating to temperature, pain, touch and pressure,...
The brain is the control center for all voluntary movement in the human body. Within the brain are lobes that control functioning, such as consciousness, emotions and personality. Different lobes are responsible for different functions. Buried...
Epilepsy is a neurological disorder characterized by regular seizures that can affect all or part of the brain. Normal signal transmission between nerve cells in the brain involves a short electrical pulse, which activates and signals to a...
Stroke affects approximately 700,000 Americans annually, according to the University Hospital website. A stroke is an abrupt deprivation of the blood flow to the brain due to a blockage or the rupture of a blood vessel in the brain. This causes a...
The Epilepsy Foundation points out that every year, 300,000 people have their first seizure. In a seizure, electrical activity in the brain becomes disrupted, resulting in physical or behavioral changes. One type of seizure is an atonic seizure,...
The human brain is made up of 100 to 150 billion neurons. The folds of these neurons on the surface of the brain, often referred to as gray matter, allow for an increase in surface area, giving humans more space for cognitive processes. The brain...
