A cognitive neuroscience perspective on the interpersonal dimension of psilocybin
Abstract
Psilocybin (O-phosphoryl-4-hydroxy-N,N-dimethyltryptamine) is an indole alkaloid  which is present in more than 150 fungi species, some of which are endemic to the UK (e.g., ). Its molecular structure closely resembles serotonin (5-hydroxytryptamine, 5-HT). In humans, psilocybin is rapidly dephosphorylated to psilocin (4-N,N-dimethyltryptamine) which functions as a non-selective partial 5-HT receptor agonist (it shows particularly high binding affinity for the 5-HT1A and 5-HT2A receptor subtypes; Nichols, 2004). A landmark study conducted at Johns Hopkins University by MacLean, Johnson & Griffiths (2011) experimentally demonstrated that a single high-dose of psilocybin can induce long-lasting (...)

A CT scan providing evidence of the nasal cycle. The more patent airway is on the right of the image; the swollen turbinates congesting the left.

The nasal cycle is unknown to many people. It refers to the alternating partial congestion and decongestion of the nasal cavities in primates. It is a visible physiological congestion of the nasal conchae (nasal turbinates) due to selective lateralised activation of one half of the autonomic nervous system by the hypothalamus (cf. hemispheric lateralisation). It completly unrelated to pathological nasal congestion and is comparable to the circadian rhythm (in the broadest sense). The ancient yoga literature describes the nasal cycle in detail and it is the focus of several pranayama (breathing) techniques which have the goal to balance the nervous (...)
