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...
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...
Salvia or Salvia Divinorum is a natural herbaceous perennial plant of the sage family that produces white flowers at the peak of its growth in summer seasons. An uprising trend has been discovered among teens and experimental drug users with...
The brain, sitting atop the spinal column, controls everything a person does, whether the functions classify as voluntary, such as standing up or running, or involuntary such as breathing and having a heartbeat. The brain itself consists of...
The cerebrum is the large upper area of the brain, which is physically divided at the midline into the right and left hemispheres. Within each hemisphere are five distinct regions, the insula, and the frontal, temporal, occipital and parietal...
The human brain controls how we interpret and integrate everything that is going on around and inside of us. The brain is divided into various sections with their own functions.
The entire body and all its functions, voluntary and involuntary, are managed by a combination of the right and left hemispheres of the brain and the lobes housed in each. The left hemisphere is in charge of the right side of the body and...
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...
Alzheimer's disease is a brain disorder that currently affects around 5.3 million Americans. It can impact several areas of the brain, and damage gets progressively worse the longer a person lives with the disorder. Damage leads to not only one of...
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 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...
The nervous system is comprised of three primary structures: the brain, spinal cord and nerves. Together, these systems control all aspects of the body from simple movements to solving complex calculations. The spinal cord and nerves play vital...
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...
Weight loss or excess weight gain may cause short-term memory disturbances. Short-term memory, also known as working memory, holds a limited number of items in your brain accessible for up to 20 to 30 seconds, according to Robert Morris...
