Drug-induced brain plasticity has been well characterized in animal studies (
1
,
2
). Brief exposure to drugs of abuse leads to insertion of calcium-permeable alpha-amino-3-hydroxy-5-methyl-4-isoxazole
propionic acid receptors and calcium-impermeable N-methyl-D-aspartate (NMDA) receptors at the ventral tegmental area synapses (
3
,
4
); prolonged drug exposure alters synaptic composition at nucleus accumbens synapses
and, in some cases, the cortical synapses (

,
6
). However, few studies have characterized potential plasticity changes in cortical
regions of human addicts.To read this article in full you will need to make a payment
