In the dark we think worse

Update: February 2019

American experts in the field of neuroscience (Michigan, USA)
found out that dim lighting can change structural
features of the brain and, thus, reduce learning.
This problem was extremely interested Joel Soler (graduate student) and
Antonio Nunez (professor at the University of Michigan), which
The reason for the study. All data about
the results of their collaboration were exhibited at the official
web page of the school.

The question of the level of illumination in the rooms is more relevant than ever,
because modernity dictates us to spend most of the time not
on the street. According to the National Institutes of Health USA
approximately 90% of the time a person is in rooms hidden from
direct sunlight. Remembering the frequent weather outside the window, you can
boldly claim insufficient energy from the sun.

low light levels.

  • Absolutely healthy before experiment rats became partially
    disorientated after four weeks of observation.
  • The animals have deteriorated memory and reaction.
  • Next, Núñez and his assistant changed the light level to bright.
    Interestingly, the rats completely returned all lost and
    reduced ability to the same level.

It’s not difficult to guess that scientists imitated cloudy days in
autumn-winter season The behavior of the rats was similar to
the behavior of those people who forgot the way to their own
car after a long day at the office, long hikes
at the mall or in the cinema.

The researchers found that all changes from
laboratory animals were reinforced by the disappearance of the synthesis
neurotrophic brain factor. This protein provides communication
between the hypothalamic neurons. Also, the doctors noticed
orexin protein, which intend to engage in the near future.

If Americans can fully explore the mechanisms of action
