The changes that caffeine causes in the brain are short-lived. For the first time, scientists have described in detail what happens to the human brain when you drink a lot of coffee.
Various studies have previously shown that coffee increases alertness and attention, and has a positive effect on memory and learning ability. Caffeine stimulates the central nervous system, but at the same time increases physical endurance and normalizes anxiety. However, this is the first time that the neurobiological causes of these effects have been described in detail.
According to the results of the study, the connection between the thalamus and the cerebellum, which is responsible for motor control, is enhanced in coffee drinkers. Coffee drinkers also have increased dynamic activity between several cerebellar and subcortical areas. We are talking about the thalamus, cerebellum, striatum, lingual, parahippocampal, and inferior occipital gyrus.
It is this activity that explains such effects as increased attention and concentration and is also responsible for improving learning and memory, according to researchers.
