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
A new “atlas” of cells that carry blood to the brain
Single-cell gene expression analyses of human cerebrovascular cells can help reveal new drug targets for Huntington’s disease and other neurodegenerative diseases.
Research advances technology of AI assistance for anesthesiologists
A new deep learning algorithm trained to optimize doses of propofol to maintain unconsciousness during general anesthesia could augment patient monitoring
