> Amphetamine tolerance is caused by excess Ca++ influx through the NMDA receptor gated calcium channels on the outer membranes of the dopamine cells bodies in the ventral tegental area, one of two areas in the brain with concentrations of dopamine producing neurons.Does this mean that amphetamine tolerance really means DA tolerance, not NE tolerance?
Does *dopamine cell* mean a neuron that produces DA, or a neuron that has DA receptors alongside the NMDA receptors?
If *dopamine cell* means a neuron that produces DA, does this mean that excess calcium influx is causing excess dopamine production/release at the other end and therefore causing tolerance?
