I saw that. Brain mechanisms create confidence about things seen

At the threshold of what we call consciousness is a brain function that makes you feel confidently aware that you are actually seeing what you see. Psychologists have observed mechanisms involved in making it work.

Protein pair quickly makes memories of new places

A new study shows that the brain’s ability to rapidly form memories of new places depends on the timely interaction of two proteins: FMRP and neurogranin.

Brain structure may predict diet success

Differences in the structure of the prefrontal cortex predict an individual’s ability to make healthier food choices, according to a new analysis of previous research in healthy men and women. The article suggests an important role of these anatomical …

Speed-accuracy tradeoff turns up gain in the brain

Widespread changes in neural activity enable people to quickly make a decision by ‘turning up the gain in the brain,’ suggests a recent human study. The findings help to resolve a central issue in our understanding of decision-making.

How does alcohol influence the development of Alzheimer’s disease?

Research has found that some of the genes affected by alcohol and inflammation are also implicated in processes that clear amyloid beta — the protein that forms globs of plaques in the brain and which contributes to neuronal damage and the cognitive i…

Gene linked to intellectual ability affects memory replay in mice

Researchers have discovered that a gene associated with human intellectual ability is necessary for normal memory formation in mice. The study shows that mice with only one copy of the gene replay shorter fragments of their previous experiences during …

What is a pseudoseizure?

The symptoms of a pseudoseizure are nearly identical to those of an epileptic seizure. However, while misfiring neurons in the brain cause epilepsy, pseudoseizures occur as a result of underlying mental health conditions, such as stress. Here, learn mo…

Where the brain processes spiritual experiences

Scientists have identified a possible neurobiological home for the spiritual experience — the sense of connection to something greater than oneself.

How emotions in facial expressions are understood

New research reveals how well fearful facial expressions are perceived in peripheral vision. Although human vision has the highest resolution when we look directly at something, we see a much wider view of the visual world in our lower resolution perip…

Brain activity patterns underlying fluent speech revealed

When we speak, we engage nearly 100 muscles, continuously moving our lips, jaw, tongue, and throat to shape our breath into the fluent sequences of sounds that form our words and sentences. A new study reveals how these complex articulatory movements a…
