- (biochemistry, pharmacology) Extreme sensitivity (of the body) to a chemical.
- 1997 October 3, Eric J. Nestler & George K. Aghajanian, “Molecular and Cellular Basis of Addiction”, in Science, volume 278, number 5335, DOI:10.1126/science.278.5335.58, pages 58-63:
- Because D 1 dopamine receptors are known to act through stimulatory heterotrimeric guanosine triphosphate-binding (G s ) proteins and activation of the cAMP pathway, up-regulation of this pathway in the nucleus accumbens could account for the functional supersensitivity of D 1 receptors observed in these neurons--which occurs in the absence of detectable changes in the receptors themselves--after chronic cocaine (or other stimulant) exposure (18 ).
