Much is already understood about the many benefits exercise provides to your physical and mental well-being, from burning energy/calories to the production of feel-good endorphins. Research continues for improved understanding of the importance of...
Some species such as cockroaches can live for up to nine days without their heads. Humans, however, cannot sustain any form of life without their heads. In fact, people seek to preserve mental capacity and foster cognitive function and performance...
The brain is a complex organ that requires constant availability of fuel for proper function. Brain cells require twice as much fuel as other types of cells in your body. This is because your brain never rests -- even when you sleep, your brain...
About 795,000 Americans each year suffer a stroke, the third largest cause of death in the United States, according to the Internet Stroke Center. Stroke occurs when blood flow to a part of the brain is interrupted. Symptoms of stroke vary...
Your brain cells are very metabolically active, meaning that they require lots of energy in order to function. The foods you eat provide your brain cells with nourishment, and also provide the building blocks for neurotransmitters, which the brain...
There is no evidence that coffee kills brain cells. In fact, the benefits of drinking moderate amounts of coffee probably outweigh the risks for most people, says MayoClinic.com. Other problems, including alcoholism, Alzheimer's disease and...
Parkinson's disease is a progressive movement disorder characterized by tremor, speech problems, movement and coordination difficulties and muscle rigidity. According to MayoClinic.com, most Parkinson's symptoms occur as a result of a fall in the...
The nerve cells in your brain -- also called neurons -- carry out a number of functions. Nerve impulses within your brain regulate memory, cognitive thought, emotions, control bodily processes such as metabolism and hunger, as well as allow for...
According to the World Health Organization, as of 2005, there are 1.6 billion cell phone users throughout the world. Because of the proximity of the cell phone to the brain, it has been questioned whether cell phone use causes brain cancer. While...
The human brain weighs between 1.3 and 1.4 kilograms and has 100 billion neurons, which are the cells in the brain that transmit electrical signals. But neurons are not the only cells found in the brain. The other groups of cells, the glial cells,...
Cayenne pepper has long been used by native peoples as a medicinal plant; it contains powerful medicinal substances you can use for a variety of purposes. No clinical evidence supports the claim that cayenne pepper kills brain cancer cells, though...
Germ cell tumors are uncommon neoplasms that develop from the primitive cells that give rise to eggs and sperm. These tumors most commonly develop in the ovaries and testicles but may occur anywhere in the body, including the brain. Germ cell...
The expanding use of mobile phones causes concerns about increasing the risk of brain cancer. Scientists who conducted a large study on the long term effects of mobile phones on the brain published their findings in the "International Journal of...
Neurons or nerve cells are the key structures in the brain that control all neurological functions. These cells have similar nutritional requirements as other cells in the body. However, certain nutrients are known to be a requirement for healthy,...
A stoke is a medical condition caused by the interruption of blood flow to the brain, which causes brain cell death. Immediate side effects of a stroke include headache, dizziness and difficulty with speech or motor coordination. The aftereffects...
Research shows that running increases production of dopamine, a substance that increases feelings of pleasure. It also helps the brain produce more cells, improving the brain's function along with sharpening memory and thinking ability.
Herbs have been used to remedy memory problems for thousands of years. Brahmi is used extensively in the 5,000-year-old Indian Ayurvedic tradition. Sage has been used in cooking and herbal medicine for 2,000 years. Ginko-biloba trees are known to...
One of the major functions of the blood is to carry oxygen from the lungs to the tissues. To accomplish this, the blood relies on a protein called hemoglobin, which binds to oxygen at the lungs and releases it at the cells. Red blood cells are...
Your nervous system -- made up the nerves throughout your body, as well as your spinal cord and brain -- contains billions of cells that communicate and work together to maintain your health. Nerve centers in the brain control muscle movement,...
Bipolar disorder is a biological disorder in which neurotransmitters--chemical messengers in the brain--malfunction, according to Psych Central. Bipolar disorder is characterized by fluctuating moods that consist of extreme excitement and intense...
Although they are commonly thought of as nuts, almonds are fruits of the almond tree, which is native to Asia and the northern half of Africa. Almond trees now also grow in the United States, particularly in California. The fruits contain several...
Dopamine is one of several neurotransmitters, chemicals released by your brain cells to allow for nerve communication. Dopamine signaling plays an important role in your mood regulation, the ability to learn and feelings of pleasure. A number of...
