					<description><![CDATA[In a groundbreaking new study published in Nature Neuroscience, researchers have unveiled a remarkable facet of psychedelic compounds that goes beyond neuronal activity to reveal intricate disruptions in the brain’s vascular responses. Psychedelics such as psilocybin and 2,5-dimethoxy-4-iodoamphetamine (DOI) have long been recognized for their profound effects on perception and cognition, primarily attributed to their [&#8230;]]]></description>

					<description><![CDATA[In a groundbreaking study published in Nature Communications, researchers have unveiled an intricate and previously underappreciated role of cholinergic basal forebrain neurons in orchestrating vascular dynamics and modulating cerebrospinal fluid (CSF) flow within the brain. This discovery sheds new light on the neural regulation of brain homeostasis and may pave the way for novel interventions [&#8230;]]]></description>
