Precision Brain Center on Instagram: "When hearing starts to decline, the brain receives less sensory input. The auditory cortex is highly plastic, so when it is under-stimulated, the brain begins to reorganize those resources elsewhere. This is why untreated hearing loss is associated with increased cognitive load, fatigue, difficulty with focus, and higher risk of cognitive decline. The brain has to work harder to fill in missing information, pulling resources away from memory, attention, and

Mushies on Instagram: "Psilocybin appears to weaken cortico-cortical feedback loops (the circuits that keep signals bouncing endlessly around the cortex) while strengthening pathways that route sensory information toward subcortical regions that turn perception into action. Alex Kwan says: “Rumination is one of the main features of depression, where people keep dwelling on the same negative thoughts. By reducing some of these feedback loops, our findings are consistent with the idea that psilocy
