Time-sensitive neurons fatigue and skew our perception of time. On some days, time flies by, while on others it seems to drag on. A new study from JNeurosci reveals why: time-sensitive neurons get worn out and skew our perceptions of time. Neurons in the supramarginal gyrus (SMG) fire in response to a […]

It’s important for successful adult-ing, experts say. Friendships can be made stronger through play-acting and problem solving. Robert Collins/Unsplash Archaeological records— and the modern-day antics of our primate relatives—make it clear that monkeying around goes way back. Less certain, however, are the developmental and evolutionary advantages that underlie our instinct […]

ANIMATION Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism. The study, published in the Journal of Neuroscience, found that paying attention can […]

Study shows how traumatic experiences can leave their mark on a person’s eyes. New research by Welsh academics shows that a patient’s pupils can reveal if they have suffered a traumatic experience in the past. Post-traumatic stress disorder can occur when a person has experienced a traumatic event such as […]

Gandy, Author provided Humans lived in what is now Mexico up to 33,000 years ago and may have settled the Americas by travelling along the Pacific coast, according to two studies by myself and colleagues published today. It has been commonly believed that the first […]
