Exposure to blue light during the day directly and immediately improves alertness and performance, says a new study. Researchers from Brigham and Women's Hospital (BWH) compared the effects of exposure to blue light with exposure to an equal amount of green light on alertness and performance in 16 study participants.

It has long been held that there are six universally recognized basic emotions that can be easily interpreted through facial expressions: happiness, sadness, fear, anger, surprise, and disgust. However, new research suggests that there are actually only four. Read on for more details. 

In a large-scale collaborative effort, scientists used two problem-solving tasks to investigate the evolution of self-control among animals. The study involved 36 species of mammals and birds. The scientists found that the species with the largest absolute brain volume showed superior cognitive powers. Read on to know more. 

Social psychologist Timothy Wilson at the University of Virginia in Charlottesville and his team found that most people have a “disengaged mind.” Wilson’s team conducted a study in which participants were asked to spend 15 minutes alone without any means of entertainment. Read on to find out the results of this study. 

It is known that neurons called grid cells to form a network known as the brain’s “inner GPS” that help humans and animals to navigate. Researchers at Dartmouth College in New Hampshire studied rats and discovered that these neurons receive spatial information from head direction cells in the thalamus. Read on to find out more.

The blood-barrier consists of a layer of cells that line the inner surface of the capillaries that regulate the passage of nutrients and waste in and out of the central nervous system. A team of researchers has developed a way of delivering medicines to the brain by bypassing the blood-brain barrier. Read on to find out more.

Researchers from Georgetown University Medical Center (GUMC) published a study which shows that the brain learns new words faster by recognizing them as complete words rather than in parts, and remembered them as pictures for future reference. Read more about their research here.

The lateral habenula, considered to be one of the oldest regions of the brain, evolution-wise, has always been linked to depression and avoidance behavior. But a new study has found that this region of the brain plays a crucial role in decision making. Read on to know more. 

A group of neuroscientists has developed a technique of making living cells and tissues bigger, which could enable biologists to image an entire brain in molecular detail using an ordinary microscope, and to resolve features that would normally be beyond the limits of optics. Read on to find out more about the technique.

A team of researchers from Columbia University Medical Center led by Yuki Oka discovered two groups of neurons in the hypothalamus that control the feeling of thirst in mice. In an attempt to understand how the brain controls the desire for water, the team used optogenetic experiments to stimulate specific neurons with a laser. Read on to find out what the team discovered.
