Small ‘window of opportunity’ for best recovery after stroke

An international study has shown, for the first time, that the capacity of the human brain to recover and rewire itself peaks around two weeks after a stroke and diminishes over time.

Regular caffeine consumption affects brain structure

Coffee, cola or an energy drink: caffeine is the world’s most widely consumed psychoactive substance. Researchers have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.

Promising biomarkers to diagnose mild traumatic brain injury

Certain plasma microRNAs could serve as diagnostic biomarkers in mild traumatic brain injury, a new study shows. The biomarkers were discovered in an animal model and they were successfully used also to diagnose mild traumatic brain injury in a subgrou…

Sounds influence the developing brain earlier than previously thought

In experiments in newborn mice, scientists report that sounds appear to change ‘wiring’ patterns in areas of the brain that process sound earlier than scientists assumed and even before the ear canal opens.

Study may lead to solutions for overeating

The 10-member team made discoveries about a specific area of the brain tied to recollection and the desire to seek and consume food. It could lead to a way to inhibit the desire to overeat.

Study explores neurocognitive basis of bias against people who look different

A new brain-and-behavior study clarifies how the ‘anomalous-is-bad’ stereotype manifests, and implicates a brain region called the amygdala as one of the likely mediators of this stereotype.

How comparable different stress tests are

Scientists use many different tests to investigate what happens in the brain in people experiencing stress. It is unclear to what extent the various methods with which subjects are placed under stress are comparable to each other. In a meta-analysis, r…

Changing the connection between the hemispheres affects speech perception

When we listen to speech sounds, our brain needs to combine information from both hemispheres. How does the brain integrate acoustic information from remote areas? In a neuroimaging study, a team of researchers applied electrical stimulation to partici…

Prediabetes may be linked to worse brain health

Researchers analyzed data from the UK Biobank of 500,000 people aged 58 years on average, and found that people with higher than normal blood sugar levels were 42% more likely to experience cognitive decline over an average of four years, and were 54% …

How a single gene alteration may have separated modern humans from predecessors

Researchers discovered a single gene alteration that may help explain cognitive differences between modern humans and our predecessor, and used that information to develop Neanderthal-like brain organoids in the lab.
