Magnetic resonance imaging studies on human methamphetamine users have also found evidence of neurodegeneration, or adverse neuroplastic changes in brain structure and function. Despite their prevalence and spectrum of functions, appreciation of their potential general importance has been elusive since their identification in the mids, and only relatively recently have they been gaining their due respect.

This is known to occur on many genes including fosB and c-fos in response to psychostimulant exposure. Pitchers and colleagues reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus. People with a family history of psychosis, or who are living with a psychotic disorder, may be more vulnerable to the long lasting effects.
