Hunger hormones impact decision-making brain area to drive behavior
A hunger hormone produced in the gut can directly impact a decision-making part of the brain in order to drive an animal’s behaviour, finds a new study by UCL (University College London) researchers. The study in mice, published in Neuron, is the first to show how hunger hormones can directly impact activity of the brain’s […]
Study Questions Value of Interim PET Imaging to Guide Frontline Hodgkin Treatment
HOUSTON — Interim PET-CT imaging (PET2) had almost no impact on clinical decision-making for Hodgkin lymphoma treated with brentuximab vedotin (Adcetris), according to a small clinical study reported here. One of 40 patients had a change in treatment based on PET2 results, regardless of whether the scans were positive or negative. Outcomes did not differ […]
Mental speed hardly changes over a lifespan: Study shows that the speed of cognitive information processing remains largely stable over decades
Mental speed — the speed at which we can deal with issues requiring rapid decision-making — does not change substantially over decades. Psychologists at Heidelberg University have come to this conclusion. Under the leadership of Dr Mischa von Krause and Dr Stefan Radev, they evaluated data from a large-scale online experiment with over a million […]
