In 2011 researchers found that these waves of electricity cause neurons in the hippocampus, the main
brain area involved with memory, to fire backward
during sleep, sending an electrical signal from their axons to their own dendrites rather than to
other cells.
Researchers specifically analyzed how different
areas of the
brain activate in sync with each
other — a property called functional connectivity —
during a period of rest.
Several of the
brain areas that had lost gray matter
during pregnancy responded with the strongest neural activity to their own babies as opposed to the photos of
other infants.
During the study of a number of aardvarks by researchers of the
Brain Function Research Group at the University of the Witwatersrand, all but one of the study animals — as well as
other aardvarks in the
area — died because of a severe drought, with air temperatures much higher than normal and very dry soil in the
area.
Last month, Ursula Voss of Bonn University in Germany and colleagues reported that even
during lucid dreaming — a state in which some people claim to be able to control their dreams — some
areas of the
brain associated with intent stayed offline, while
other areas associated with consciousness were active.
Some
brain imaging studies have shown activation of speech
areas during mathematical tasks, while
others have not.
Specific
brain areas, most notably the anterior cingulate cortex (ACC) and anterior insula, activated
during functional magnetic resonance imaging (fMRI) both when subjects experienced pain and when another person present experienced pain, whereas
other areas activated only
during the direct sensation of pain [3].
Vascular dementia, on the
other hand, appears to occur when blood flow to certain
areas of the
brain is interrupted, such as
during strokes and so - called mini-strokes.
And studies using functional MRI measures have shown that the amount of cortical
brain area used is greater
during eccentric contractions than in concentric contractions (Yao et al. 2014), while functional connectivity between the primary motor cortex and
other parts of the
brain is reduced (Yao et al. 2016).
Since the prefrontal cortex and
other areas of the
brain responsible for impulse control, willpower, and healthy decision - making are not fully developed, risk - taking behavior often happens
during this stage of life.
