Medico Plasma on Instagram: "All cerebellar efferent output follows a uniform plan. The first neuron is always the Purkinje cell of the cerebellar cortex, whose inhibitory impulses are relayed to the deep cerebellar nuclei acting as the second neuron. From these nuclei, fibres leave the cerebellum as centrifugal pathways and influence motor control indirectly through brainstem nuclei and the cerebral cortex. From the nodulo-floccular lobe, efferent fibres are directed to the vestibular system. N

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
