“Exactly why this happens is unclear. But new research led by neuroscientists at the University of North Carolina at Chapel Hill School of Medicine may have literally shined a light on the answer, one that could lead to the discovery of new mental health therapies. A report of the study appears March 22 in the journal Neuron.”
“This result when watching such a formal dance as ballet is striking in comparison to the similar enhanced response the authors found in empathic observers when watching an Indian dance rich in hand gestures. This is important because it shows that motor expertise in the movements observed is not required to have enhanced neural motor responses when just watching dance performances.
The authors suggest that spectators covertly simulate the dance movements for styles that they regularly watch, causing the increased corticospinal excitability.”
“There are no acknowledged biomarkers for autism today. Researchers at Berzelii Centre and the Science for Life Laboratory in Uppsala who, in collaboration with colleagues at Linnaeus University in Sweden and the Faculty of Medicine in Tehran, Iran, who have discovered some promising biomarkers.”
“In the 1930s, the psychologist B. F. Skinner devised the operant conditioning chamber, or “Skinner box,” in which a lever press by an animal triggered either a reinforcing stimulus, such as delivery of food or water, or a punishing stimulus, such as a painful foot shock. Rats placed in a Skinner box will rapidly learn to press a lever for a food reward and to avoid pressing a lever that delivers the shock. “
