A single dose of psilocybin has been shown to have persistent antidepressant effects in human clinical trials. In animal models, psilocybin induces neuroplasticity in cortex and hippocampus. Deciphering the acute and persistent effects of psilocybin on the human brain is a critical step towards better understanding the neurobiology of psychedelics.

In my first neuroscience course at Columbia University, I learned about the homunculus. This “little man” is depicted as an upside-down representation of the human body moving from toe to head in a portion of the cerebral cortex that controls movement. Wilder Penfield, the trailblazing Canadian-American neurosurgeon, created the homunculus metaphor after mapping areas of the human brain by using direct electrical stimulation in awake patients in the 1930s.
