Multidisciplinary team completes first-ever EXIT to ventricular pacing procedure
Researchers at Children's Hospital Colorado (Children's Colorado) have completed the first-ever EXIT (Ex Utero Intrapartum Treatment) to ventricular pacing procedure. The patient, a 36-week fetus, who suffered from complete atrioventricular block (CAVB) and cardiac dysfunction, was at high risk of dying before delivery. While still attached to its mother via the umbilical cord, the baby received a temporary pacemaker, which stabilized its dangerously low and irregular heart rate and ensured enough blood flow from the heart to the rest of its body for delivery.

Researcher explains how statistics, neuroscience improve anesthesiology
It's intuitive that anesthesia operates in the brain, but the standard protocol among anesthesiologists when monitoring and dosing patients during surgery is to rely on indirect signs of arousal like movement, and changes in heart rate and blood pressure. Through research in brain science and statistical modeling, Emery N. Brown, an anesthesiologist at Massachusetts General Hospital and neuroscientist at MIT's Picower Institute for Learning and Memory, is putting the brain at the center of the field. His findings allow him to safely give less anesthesia, for example, which can have important benefits for patients.

Link between hallucinations and dopamine not such a mystery, finds study
Researchers at Columbia University Irving Medical Center (CUIMC) and New York State Psychiatric Institute (NYSPI) found that people with schizophrenia who experience auditory hallucinations tend to hear what they expect, an exaggerated version of a perceptual distortion that is common among other people without hallucinations. Those with hallucinations and other psychotic symptoms are known to have elevated dopamine, the main area of focus for available treatments for psychosis, but it was unclear how this could lead to hallucinations. The researchers found that elevated dopamine could make some patients rely more on expectations, which could then result in hallucinations.

Lab-grown human cerebellar cells yield clues to autism
Increasing evidence has linked autism spectrum disorder (ASD) with dysfunction of the brain's cerebellum, but the details have been unclear. In a new study, researchers at Boston Children's Hospital used stem cell technology to create cerebellar cells known as Purkinje cells from patients with tuberous sclerosis complex (TSC), a genetic syndrome that often includes ASD-like features. In the lab, the cells showed several characteristics that may help explain how ASD develops at the molecular level.
