The animal models of addiction are particularly useful because animals that are addicted to a substance show behaviors similar to human addicts. This implies that the structural changes that can be observed after the animal ingests a drug can be correlated with an animal's behavioral changes, as well as with similar changes occurring in humans.
Nicotine addiction is a disorder which alters different neural systems such as dopaminergic, glutamatergic, GABAergic, serotoninergic, that take part in reacting to nicotine. [43] In 2015 the psychological and behavioral effects of e-cigarettes were studied using whole-body exposure to e-cigarette aerosol, followed by a series of biochemical ...
The effects of psychedelics on neuroplasticity appear to be dependent on serotonin 5-HT 2A receptor activation, as they are abolished in 5-HT 2A receptor knockout mice. [7] Non-hallucinogenic serotonin 5-HT 2A receptor agonists, like tabernanthalog and lisuride, have also been found to increase neuroplasticity, and to a magnitude comparable to ...

Exposure to certain recurring stimuli leads to demethylation of particular loci and remethylation in a pattern that leads to a response to that particular stimulus. Like the histone readers, erasers and writers also modify ...
