Differential effects of clonidine, haloperidol, diazepam and tryptophan depletion on focused attention and attentional search.

Differential effects of clonidine, haloperidol, diazepam and tryptophan depletion on focused attention and attentional search.

As the catecholamines have long been implicated in attentional processes, the present investigation compared the effects of the mixed alpha 1/alpha 2 adrenoceptor agonist clonidine (CLO), the benzodiazepine diazepam (DZP), the D1/D2 antagonist haloperidol (HAL) and a low-tryptophan drink (Lo-TRP) on...
