| How micro-circuits in the brain regulate fear Posted: 16 Jul 2021 08:24 AM PDT The brain mechanisms underlying the suppression of fear responses have attracted a lot of attention as they are relevant for therapy of human anxiety disorders. Despite our broad understanding of the different brain regions activated during the experience of fear, how fear responses can be suppressed remains largely elusive. Researchers have now discovered that the activation of identified central amygdala neurons can suppress fear responses. |
| New theory suggests blood immune and clotting components could contribute to psychosis Posted: 16 Jul 2021 08:24 AM PDT A scientific review has found evidence that a disruption in blood clotting and the first line immune system could be contributing factors in the development of psychosis. |
| New UK study reveals extent of brain complications in children hospitalized with COVID-19 Posted: 16 Jul 2021 08:24 AM PDT Although the risk of a child being admitted to hospital due to COVID-19 is small, a new UK study has found that around 1 in 20 of children hospitalized with COVID-19 develop brain or nerve complications linked to the viral infection. |
| High daily screen time linked to cognitive, behavioral problems in children born extremely preterm Posted: 15 Jul 2021 11:24 AM PDT Among 6- and 7-year-olds who were born extremely preterm -- before the 28th week of pregnancy -- those who had more than two hours of screen time a day were more likely to have deficits in overall IQ, executive functioning (problem solving skills), impulse control and attention, according to a new study. |
| Emotion, cooperation and locomotion crucial from an early age Posted: 15 Jul 2021 09:46 AM PDT What are the fundamental skills that young children need to develop at the start of school for future academic success? Researchers examined the links between emotion knowledge, cooperation, locomotor activity and numerical skills in 706 pupils aged 3 to 6. The results show that emotion knowledge, cooperative social behavior and locomotor activity are interrelated and associated with numerical skills. These results suggest that locomotor activity should be added to these fundamental skills. |
| A common ancestor for cells involved in hearing and touch Posted: 12 Jul 2021 12:03 PM PDT There are striking similarities in the development of two types of specialized sensory cells: the so-called 'hair cells' that receive sound vibrations in the inner ear, and the Merkel cells that sense light touch at the surface of the skin. These developmental similarities are a legacy of shared evolutionary history. |
