What affects brain activity?

All vertebrate creatures have a central nervous system operated by the brain, a highly complex organ that acts as a central command for the whole body. The brain is the center for sensory, motor, excitement and neurotransmitting in the body. Brain activity is literally electricity caused by the burning of neurons when the brain is its constant routine. As internal and external stimuli change, brain activity can also change.

brain activity can be changed by ingestion or exposure to certain medicines. Most drugs used to treat psychological problems in some way affect brain activity, but also many other substances. Caffeine, heroin, antidepressants and sedatives can affect how fast and often neurotransmitters fire. Although this effect may be temporary, some studies show that prolonged use of the drug may have prolonged effects.

Disruption of normal sleeping habits may, according to some studies, have a serious effect on brain wool activity. Although may seem logiIt is that brain activity decreases with sleep deprivation, some evidence shows that the activity in some parts of the brain is actually increasing, as if the brain compensated for a lack of rest. Unfortunately, insomnia also disrupts cognitive and motor functions, usually beats brain experiments to maintain normal performance levels.

hormones in the body can also cause significant alternation to activity in the brain. In one study, small doses of estrogen were administered after menopausal women and monitored for changes in brain activity. In many cases, women treated with hormone showed an increased memory function. Studies like this have led to further research in menstrual women because hormonal levels fluctuate during the monthly menstrual cycle. New research suggests that the preferences of confusing and sexual attraction, both partially controlled brain activity, may, depending on the menstrual cycle of the subject.

the brain controls the sensesLike perception such as touch, smell, taste and hearing. Some sensory external stimuli can cause activity in the brain to change from self -preservation. For example, if the deer lifts the scent of the predator, its brain can activate flight response to get out of danger.

The level of brain waves seems to some extent influenced by the selection of lifestyle. It turned out that stress, religious devotion and even culture have some level of effect on how the brain works. Some experts believe that a reduction in stress level and focusing on a healthy lifestyle can lead to an improvement in brain activity.

Brain activity study is mostly performed through the type of observational research called electroencephalography. This method uses the use of sensors that can measure and map the amount of activity in the brain. By measuring patterns in different brain waves, neurologists and scientists, the brain's ability to respond to stimuli and also to see any development areas affected by activityu suggest problems with nervous connections such as epilepsy.
