A hallucination is a perception that resembles a true perception but occurs when there is no external input. 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
