Researchers have discovered a gene signature in healthy brains that echoes the pattern in which Alzheimer’s disease spreads through the brain much later in life. The findings could help uncover the molecular origins of this devastating disease, and may…

Neurodevelopmental model of Williams syndrome offers insight into human social brain

In a study spanning molecular genetics, stem cells and the sciences of both brain and behavior, researchers have created a neurodevelopmental model of a rare genetic disorder that may provide new insights into the underlying neurobiology of the human s…

Transcranial magnetic stimulation revealed differences between brain activity of people who dream and people who do not dream

Measurements demonstrated that the brain activity of people who dream during NREM sleep, compared to people who do not dream, is closer to the brain activity of awake people.

Sex hormones skew outcomes in clinical trials – here’s how

Clinical research often excludes females from their trials under the assumption that “one size fits all,” that a painkiller or antidepressant will be equally effective in subjects of either sex…

Positive teacher-student relationships boost good behaviour in teenagers for up to four years

A new study has found that having a positive relationship with a teacher around the age of 10-11 years old can markedly influence the development of ‘prosocial’ behaviours such as cooperation and…

Developmental psychology: Little strategists

Sharing with others and getting something back: Preschoolers expect someone who has benefitted from their generosity to reciprocate when an opportunity arises to do so.

Device reduces risk of brain injury after heart valve replacement

Among patients with severe aortic stenosis (narrowing of the aortic valve) undergoing transcatheter aortic valve implantation, the use of a cerebral protection device (a filter that captures debris [tissue and plaque] dislodged during the procedure) re…

In search of neurobiological factors for schizophrenia

It is impossible to predict the onset of schizophrenic psychosis. If factors linked to a risk of psychosis can be identified, however, these may yield significant insights into its underlying mechanisms. Scientists have now established a link between p…

Dreaming also occurs during non rapid eye movement sleep

Measurements demonstrated that the brain activity of people who dream during NREM sleep, compared to people who do not dream in NREM sleep, is closer to brain activity of awake people.
