Summary: Pregnancy and lactation trigger major physiological changes, including shifts in body temperature and environmental preferences. Researchers have now discovered that postpartum female mice develop a long-term preference for cooler environments, driven by brain changes.These changes involve a specific group of neurons in the preoptic area (POA) that express estrogen...
Summary: A new study finds that adults with ADHD show brain changes similar to those seen in early-stage dementia, including higher iron accumulation and increased neurofilament light chain (NfL) levels in the blood. Using advanced MRI scans and blood tests, researchers identified elevated iron in key brain regions and signs...
Summary: A new study reveals how the brain reprocesses and refines memories during sleep, particularly those related to spatial learning. Researchers tracked rats’ hippocampal neuron activity for up to 20 hours and found that memory patterns first echoed the learning phase and then gradually shifted to match the recollection phase...
Summary: Researchers used a virtual reality game and functional MRI to uncover how children’s brains with ADHD respond differently during active tasks. Unlike traditional brain scans taken during rest, this immersive approach revealed distinct patterns of neural communication in ADHD, especially in deeper brain structures.The study shows that ADHD-related brain...
