In some genetic cases of microcephaly, stem cells fail to launch

In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new study that may provide important clues to understanding how the Zika virus affects the developing brain.

Sick animals limit disease transmission by isolating themselves from their peers

Sick wild house mice spend time away from their social groups, leading to a decrease in their potential for disease transmission according to a new study by evolutionary biologists from the…

Evidence of changes to children’s brain rhythms following ‘brain training’

New research questions the strong claims that have been made about the benefits of ‘brain training’ — enhanced mental skills, a boost to education, improved clinical outcomes and sharper everyday functioning. This new study found evidence that ‘brain …

Intravenous glyburide treatment may reduce dangerous brain swelling after stroke

A phase 2 clinical trial of a drug that may alleviate brain swelling — a dangerous stroke complication — suggests the treatment may help reduce brain injury and death, and information from the study will help design the phase 3 trial.

Mechanism that alters neural excitability offers window into neuropsychiatric disease

Researchers show, for the first time, that the well-known mechanism of gene expression control — dynamic changes in DNA methylation — is also involved in changes to the excitability of neural cells. This suggests that DNA methylation changes that alt…

Brain damages caused by Zika virus congenital infection go beyond microcephaly

A recent study published by Brazilian researchers indicates brain malformations induced by Zika virus congenital infection. More than microcephaly, the research indicates other neurological changes such as reduction in brain volume, cortical developmen…

How sleep deprivation harms memory

Researchers have discovered a piece in the puzzle of how sleep deprivation negatively affects memory.

Too much activity in certain areas of the brain is bad for memory and attention

Researchers have found that faulty inhibitory neurotransmission and abnormally increased activity in the hippocampus impairs our memory and attention.

New report details pre- and postnatal brain defects from Zika virus

Researchers from the epicenter of the current Zika virus outbreak have released a report on imaging findings in babies and fetuses infected with the Zika virus. Zika virus is most dangerous when transmitted from a pregnant mother to her fetus, increasi…

MRI scans may be useful in diagnosing chronic traumatic encephalopathy, study shows

Doctors have used an MRI-based technique to detect shrinkage in brain consistent with CTE, which, they say, could lead to diagnosis in the living.
