Laughing gas relieves symptoms in people with treatment-resistant depression

Researchers have found that a single, one-hour treatment that involves breathing in a mixture of oxygen and the anesthetic drug nitrous oxide — otherwise known as laughing gas — can significantly improve symptoms in people with treatment-resistant de…

Study shows adaptive brain response to stress, and its absence in people with depression

A new study identifies a novel biomarker indicating resilience to chronic stress. This biomarker is largely absent in people suffering from major depressive disorder, and this absence is further associated with pessimism in daily life, the study finds.

Brain connections mean some people lack visual imagery

New research has revealed that people with the ability to visualize vividly have a stronger connection between their visual network and the regions of the brain linked to decision-making. The study also sheds light on memory and personality differences…

As novel sights become familiar, different brain rhythms, neurons take over

As ‘visual recognition memory’ emerges in visual cortex, one circuit of inhibitory neurons supplants another and slower neural oscillations prevail, according to a new study.

Taking short breaks may help our brains learn new skills

In a study of healthy volunteers, researchers have mapped out the brain activity that flows when we learn a new skill, such as playing a new song on the piano, and discovered why taking short breaks from practice is a key to learning.

Weak brain waves may warn of age-related neurodegenerative disease

Weakened electrical signals in the brain may be an early warning sign of age-related neurodegenerative diseases such as Alzheimer’s disease.

First glimpse of brains retrieving mistaken memories observed

Scientists have observed for the first time what it looks like in the key memory region of the brain when a mistake is made during a memory trial. The findings have implications for Alzheimer’s disease research and advancements in memory storage and en…

Researchers discover a new cause for the cerebral cavernous malformation

Researchers have recently uncovered a new gene mutation responsible for the non-familial patients of cerebral cavernous malformation (CCM) — a brain vascular disorder which inflicted about 10-30 million people in the world.

Lack of math education negatively affects adolescent brain and cognitive development

Adolescents who stopped studying math showed a reduction in a critical brain chemical for brain development. This reduction in brain chemical was found in a key brain area that supports math, memory, learning, reasoning and problem solving.

Computers can now predict our preferences directly from our brain

A research team demonstrates it is possible to predict individual preferences based on how a person’s brain responses match up to others. This could potentially be used to provide individually tailored media content — and perhaps even to enlighten us …
