Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
The brain's ability to adapt toward active functions allows humans to specialize in specific processes based on relative use and activity. For example, a right-handed person may perform any movement poorly with their left hand but continuous practice with the non-dominant hand can cause one to become ambidextrous .
“In the body, choline helps maintain cell structure, and produces acetylcholine, an important neurotransmitter for memory, mood, muscle control, and other brain and nervous system functions ...
A team of leading brain scientists developed this web-based brain health program, which has been proven to be effective in hundreds of studies. These exercises can: These exercises can: Improve ...
A new study from the Salk Institute for Biological Studies has identified a brain circuit that slows the breath to calm the mind.
Changes in brain activity are closely coupled with changes in blood flow in those areas, and knowing this has proved useful in mapping brain functions in humans. The measurement of haemodynamic response, in a clinical setting, can be used to create images of the brain in which especially active and inactive regions are shown as distinct from ...
Dementia is an umbrella term for a range of conditions that affect how the brain works, reducing the ability to remember, think and reason. It mainly affects older people and gets worse over time. Health and lifestyle factors such as high blood pressure and smoking are known to increase the risk of developing dementia. [65]
