Dose of nature is just what the doctor ordered

People who visit parks for 30 minutes or more each week are much less likely to have high blood pressure or poor mental health than those who don’t, according to new research by Australian and UK…

Understanding Risk Factors Involved in Initiation of Adolescent Alcohol Use

Underage drinking is a major public health and social problem in the U.S. The ability to identify at-risk children before they initiate heavy alcohol use has immense clinical and public health implications. A new study has found that demographic factor…

‘It’s my turn!’ Value of turn-taking not understood until the age of 5

Children fail to understand the importance of turn-taking until the age of 5 years, say researchers, likely because it requires complex cognitive skills.

Human brain houses diverse populations of neurons, new research shows

A team of researchers has developed the first scalable method to identify different subtypes of neurons in the human brain. The research lays the groundwork for ‘mapping’ the gene activity in the human brain and could help provide a better understandin…

Scientists reveal single-neuron gene landscape of the human brain

A team of scientists has completed the first large-scale assessment of single neuronal ‘transcriptomes.’ Their research reveals a surprising diversity in the molecules that human brain cells use in transcribing genetic information from DNA to RNA and p…

New study provides unprecedented insight into the fine details of neuronal communication

For communication between neurons to occur, an electrical impulse, called an action potential, must travel down an axon to its synaptic terminal. A major technical challenge impeding the direct examination of this process, axonal excitability, is the s…

Precise control of brain circuit alters mood

By combining super-fine electrodes and tiny amounts of a very specific drug, researchers have singled out a circuit in mouse brains and taken control of it to dial an animal’s mood up and down. Stress-susceptible animals that behaved as if they were de…

Not only trauma but also the reversal of trauma is inherited

Behaviors caused by traumatic experiences in early life are reversible. Researchers could demonstrate that environmental enrichment allows trauma-related symptoms in mice to be reversed. This is the first evidence that positive environmental factors ca…

Scientists learn more about how star-shaped brain cells help us learn

A molecule that enables strong communication between our brain and muscles appears to also aid essential communication between our neurons, scientists report.

3D Brain-on-a-chip

To study brain cell’s operation and test the effect of medication on individual cells, the conventional Petri dish with flat electrodes is not sufficient. For truly realistic studies, cells have to flourish within three-dimensional surroundings. Rese…
