Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD).

Whenever we have to acquire new knowledge under stress, the brain deploys unconscious rather than conscious learning processes. Neuroscientists at the Ruhr-Universität Bochum have discovered that this switch from conscious to unconscious learning systems is triggered by the intact function of mineralocorticoid receptors.

Researchers have reverse-engineered the outlines of a disrupted prenatal gene network in schizophrenia, by tracing spontaneous mutations to where and when they likely cause damage in the brain. Some people with the brain disorder may suffer from impaired birth of new neurons, or neurogenesis, in the front of their brain during prenatal development, suggests the study.

Autism is marked by several core features — impairments in social functioning, difficulty communicating, and a restriction of interests. Though researchers have attempted to pinpoint factors that might account for all three of these characteristics, the underlying causes are still unclear. Now, a new study suggests that two key attentional abilities — moving attention fluidly and orienting to social information — can be checked off the list, as neither seems to account for the diversity of symptoms we find in people with autism.

Anemia, or low levels of red blood cells, may increase the risk of dementia, according to a study published in the July 31, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology

Physicists and neuroscientists from The University of Nottingham and University of Birmingham have unlocked one of the mysteries of the human brain, thanks to new research using Functional Magnetic Resonance Imaging (fMRI) and electroencephalography (EEG). The work will enable neuroscientists to map a kind of brain function that up to now could not be studied, allowing a more accurate exploration of how both healthy and diseased brains work.
