Scientists unearth another brain-shrinking mammal

A study of moles reveals that cold weather — not lack of food — drives the rare phenomenon of reversible brain shrinkage in mammals.

Molecular changes in the brain in the aftermath of a traumatic event may help explain long-term susceptibility or resilience

Social avoidance is a common symptom of PTSD, and scientists working to better understand why have laboratory evidence that while stress hormone levels consistently increase in the immediate aftermath of a traumatic event, there can be polar opposite c…

New clues into how the circadian clock helps the brain recover after injury

A type of brain cell that can renew itself is regulated by circadian rhythms, providing significant insights into how the body’s internal clock may promote healing after traumatic brain injuries (TBI), according to new research.

Exercise may be key to developing treatments for rare movement disorder

Spinal cerebellar ataxia 6 (SCA6) is an inherited neurological condition which has a debilitating impact on motor coordination. Affecting around 1 in 100,000 people, the rarity of SCA6 has seen it attract only limited attention from medical researchers…

Novel analysis shows the experience of reward increases connectivity between the default mode network and other brain regions

In line with other studies, during the reward-processing task, researchers observed decreased activation of the default mode network (DMN) and relative increased activation of other networks.

An unstable, flake-like network in the making

During development, the cells of an embryo divide until a fully functional organism emerges. One component of the cell is especially important during this process: the cell cortex. This fine network of hair-like filament structures (called actin) just …

Towards a better understanding of depression

Human beings and fruit flies have very little in common — at first sight. However, studying these flies it is in fact possible to find out more about human nature, particularly when it comes to depressive disorders. It is on this basis that scientists…

The hemispheres are not equal: How the brain is not symmetrical

Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right. Scientists have now discovered heritable underpinnings of brain asymmetry and how much we sha…

Resident physicians report COVID-19 impacts

A study assessed resident physicians’ perceptions, coping strategies and self-reported levels of depression, anxiety and stress experienced during the early phase of the pandemic.
