Sleepless Night Leaves Some Brain Cells As Sluggish As You Feel

A study that recorded directly from neurons in the brains of 12 people found that sleep deprivation causes the bursts of electrical activity that brain cells use to communicate to become slower and weaker, a team reports online Monday in Nature Medicine. The finding could help explain…

Depressed fathers risk not getting help

Depressed fathers risk not getting help

Postnatal depression among new mothers is a well-known phenomenon. Knowledge about depression in new fathers, however, is more limited. A new study shows that depression among new fathers may be more common than previously believed. There is also a major risk that it remains undetected using today’s screening instruments, and that fathers do not receive the help they need.

Probability calculations: even babies can master it

Probability calculations: even babies can master it

One important feature of the brain is its ability to make generalizations based on sparse data. By learning regularities in our environment it can manage to guide our actions. As adults, we have therefore a vague understanding of which events are likely to happen. So far, it was unclear when we begin to estimate likelihood. Scientists have now shown that even six-month-old babies can probability.

Lack of oxygen, not blood flow, delays brain maturation in preterm infants

Lack of oxygen, not blood flow, delays brain maturation in preterm infants

Previously, it was believed that lack of blood flow was causing preterm brain cells to die. Instead, these critically important cells simply fail to develop normally, report investigators. This finding creates an opportunity to determine ways to restore oxygen loss and potentially reduce life-long impacts of preterm survivors.
