Test subjects in an Ohio State University study were shown a series of photographs of different facial expressions. Researchers pinpointed an area of the brain that is specifically attuned to picking up key muscle movements (here, labeled AU for ‘action units’) that combine to express emotion.

New machine learning algorithm can identify the facial expression a person is looking at based on neural activity.

After a stroke, there is inflammation in the damaged part of the brain. Until now, the inflammation has been seen as a negative consequence that needs to be abolished as soon as possible. But, as it turns out, there are also some positive sides to the inflammation, and it can actually help the brain to self-repair.

A new study reports hungry fish sense objects differently and take more risks when hunting than well fed fish.

In a study exploring the relationship between memory for specific past experiences and recovery from strong negative emotions, research psychologists report that episodic memory may be more important in helping midlife and older adults recover from a negative event than it is for younger adults.

New research reports one brain hemisphere remains more awake than the other when sleeping somewhere new. 

Long before Alzheimer’s disease can be diagnosed clinically, increasing difficulties building cognitive maps of new surroundings may herald the eventual clinical onset of the disorder, according to new research.

New research suggests actin filaments that control the shape of neuron cells may also be the key to the molecular machinery that forms and stores long-term memories.

Scientists have elucidated for the first time how a notoriously elusive serotonin receptor functions with atom-level detail. The receptor transmits electrical signals in neurons and is involved in various disorders, meaning that the discovery opens the way for new treatments.

Researchers have mapped out a circuit of neurons that is responsible for motor impairment–such as difficulty walking–in patients with Parkinson’s disease.

Brain waves that spread through the hippocampus are initiated by a method not seen before–a possible step toward understanding and treating epilepsy, according to researchers at Case Western Reserve University.

Researchers have conducted a study examining the effect ecstasy has on different parts of the brain.

Finally this week researchers have found that drawing pictures of information that needs to be remembered is a strong and reliable strategy to enhance memory.
