For high schoolers, summer starts with extra exposure to biomedical science
Just before school was out for summer, high school students from Everett and Lawrence toured life sciences research labs at MIT to get information and inspiration
Circuit model may explain how deep brain stimulation treats Parkinson’s disease symptoms
Stimulation of subthalamic nucleus interrupts a cycle of runaway beta-frequency rhythms and restores ability of interneurons to regulate rhythms in the brain’s striatum, improving movement, study suggests
Anesthetic drastically diverts the travels of brain waves
Under propofol general anesthesia very slow frequency traveling waves transform and dominate, redirecting and disrupting the higher frequency traveling waves associated with conscious function
A single memory is stored across many connected brain regions
Innovative brain-wide mapping study shows that “engrams,” the ensembles of neurons encoding a memory, are widely distributed, including among regions not previously realized
Neurons are fickle. Electric fields are more reliable for information.
A new study suggests that electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons
