Isolated Brain Regions Display Sleep-Like Activity in Awake Patients, Study Reveals

Brain regions surgically isolated to treat epilepsy maintain sleep-like electrical activity for years post-procedure, according to recent findings. The study provides new insights into consciousness and unconscious states in neural tissue. Researchers compared EEG readings from disconnected brain areas with those of sleeping and awake individuals.

Brain Isolation Triggers Persistent Sleep Patterns

According to recent research published in PLoS Biology, portions of the brain surgically disconnected from the rest of the organ continue to exhibit slow, sleep-like brain waves even when the individual is fully awake. The findings, based on studies of children who underwent epilepsy surgery, provide new understanding of how consciousness manifests in neural tissue and what constitutes unconscious states within specific brain regions.

Brain’s Leptin-Sensitive Cells Found to Suppress Anxiety, Enabling Exploration and Feeding in Stressful Environments

A specialized group of neurons in the brain’s lateral hypothalamus expressing leptin receptors actively reduces anxiety to promote exploration and feeding in exposed areas, according to a new study. The research reveals how these cells counteract prefrontal anxiety signals, enabling animals to adapt behavior in stressful environments. These findings may provide insights into anxiety and restrictive eating disorders.

Neural Circuitry That Counters Anxiety Identified

Scientists have discovered a specific population of neurons in the lateral hypothalamus that counteracts anxiety to enable exploration of exposed areas and feeding in threatening environments, according to research published in Nature Neuroscience. These leptin receptor-expressing (LepR) neurons show increased activity when animals venture into anxiety-provoking spaces, and their artificial activation reduces anxiety-related behaviors while enabling adaptive responses.
