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…

Wait for it: Serotonin and confidence at the root of patience in new study

Serotonin keeps mice hanging on if they are sure of getting rewards, but not sure when.

For anxiety, a single intervention is not enough

No matter which treatment they get, only 20 percent of young people diagnosed with anxiety will stay well, researchers report. The study followed 319 young people aged 10 to 25 who had been diagnosed with separation, social, or general anxiety disorder…

Bigger human brain prioritizes thinking hub — at a cost

Some human brains are nearly twice the size of others — but how might that matter? Researcher have discovered that these differences in size are related to the brain’s shape and the way it is organized. The bigger the brain, the more its additional ar…

Your brain is multitasking, using a hunger peptide that tells you when to eat

Scientists have figured out how your brain tells you that you are hungry. They found that a neuropeptide associated with appetite is sent into the cerebrospinal fluid to connect with neurons responsible for alerting hunger.
