Yin and yang of serotonin neurons in mood regulation

Low levels of serotonin in the brain are known to play a role in depression and anxiety, and it is customary to treat these disorders with medications that increase the amount of this neurotransmitter. However, a new study suggests that this approach m…

Deciphering the role of brain layers

New research sheds light into the role of layers in the brain. The study shows that the formation of layers speeds the development of neuronal circuits although, surprisingly, it is not crucial for the establishment of functional and cell-type specific…

Brainstem ‘stop neurons’ make us halt when we walk

A population of ‘stop cells’ in the brainstem is essential for the ability of mice to stop their locomotion, according to a new study. Researchers report a brainstem pathway specifically dedicated to enforce locomotor arrest; its selective activation s…

New method for imaging marmoset brains

A new system for imaging the activity of individual neurons in the marmoset brain has been developed by scientists. The study shows how amplifying genetically encoded fluorescent signals with TET-inducible gene expression allows hundreds of individual …

Running prevents postnatal side effects of epilepsy drugs in mice

The simple act of running may be sufficient to prevent long-term cognitive impairments caused by prenatal exposure to antiepileptic drugs, according to a study. The findings revealed that prenatal exposure to a commonly used antiepileptic drug called v…

How exercise may energize brain cell function: Animal study

As we age or develop neurodegenerative diseases such as Alzheimer’s, our brain cells may not produce sufficient energy to remain fully functional. Researchers have discovered that an enzyme called SIRT3 that is located in mitochondria — the cell’s po…

Brains with autism adapt differently during implicit learning

A crucial difference in the way learning occurs in the brains of adults with autism spectrum disorder (ASD) has been identified by scientists. They have examined how the brains of typical and ASD individuals gradually became adapted to visual patterns …

Seven minutes of meditation can reduce racial prejudice, study finds

A popular meditation technique that’s intended to create feelings of kindness can also reduce prejudice, according to new research. The study found that just seven minutes of Loving-kindness meditation (LKM), a Buddhist practise that promotes unconditi…

WSU psychologists dispute continuum theory of sexual orientation

Statistical analysis finds categorical distinctions, health issues.Washington State University researchers have established a categorical distinction between people who are heterosexual and those…

Improving fitness may counteract brain atrophy in older adults, study shows

Older adults that improved their fitness through a moderate intensity exercise program increased the thickness of their brain’s cortex, the outer layer of the brain that typically atrophies with Alzheimer’s disease, according to a new study. These effe…
