How psychedelic drug psilocybin works on brain

To see how psychedelics impact the claustrum, a mysterious region of the brain believed to control the ego, researchers compared the brain scans of people after they took psilocybin with their scans after taking a placebo.

Memory consolidation during REM sleep

Researchers have found that activity in adult-born neurons (ABNs) in the hippocampus, which is a brain region associated with memory, are responsible for memory consolidation during REM sleep. Identifying the role of specific neurons in memory function…

Areas of brain where recognition and identification occur

Using ”sub-millimeter” brain implants, researchers have been able to determine which parts of the brain are linked to facial and scene recognition.

Stimulating research gives new treatment hope for Tourette Syndrome

New research has found that delivering electrical pulses to the wrist can significantly reduce the amount and severity of tics experienced by individuals with Tourette Syndrome (TS), giving new hope for an effective treatment.

Restoring vision by gene therapy

Macular degeneration is one of the major reasons for visual impairment. Scientists have now developed a therapeutic approach based on gene therapy. They managed to activate degenerated photoreceptors using near-infrared light.

Study ties stroke-related brain blood vessel abnormality to gut bacteria

Researchers found that the presence of abnormal bundles of brittle blood vessels in the brain or spinal cord, called cavernous angiomas (CA), are linked to the composition of a person’s gut bacteria. Also known as cerebral cavernous malformations, thes…

Scientists discover that nicotine promotes spread of lung cancer to the brain

Among people who have the most common type of lung cancer, up to 40% develop metastatic brain tumors, with an average survival time of less than six months. But why non-small-cell lung cancer so often spreads to the brain has been poorly understood.

Chronic stress? Limiting inflammatory signaling to specific brain circuits

Chronic stress is associated with the pathogenesis of psychological disorders such as depression. A study is the first to identify the role of a neuronal receptor that straddles the intersection between social stress, inflammation, and anxiety in roden…

Why some older adults remember better than others

New research marks the beginning of an effort to better understand memory and memory loss in older adults using advanced imaging and data analysis techniques.

Studies of brain activity aren’t as useful as scientists thought

Hundreds of published studies over the last decade have claimed it’s possible to predict an individual’s patterns of thoughts and feelings by scanning their brain in an MRI machine as they perform some mental tasks. But a new meta-analysis by researche…
