Hallucinations

There are three known neurochemical pathways which cause hallucinations:

• Activation of dopamine D2 receptions (D2Rs) with psychostimulants
• Activation of serotonin 5HT2A receptors (HT2ARs) with psychedelics
• Blockage of glutamate NMDA receptors (NMDARs) with dissociative anaesthetics
