Behaviors driven by intrinsic motivation are critical for development and optimization of physical and brain functions, but their underlying mechanisms are not well studied due to the complexity and autonomy of the behavior. Songbirds, such as zebra finches, offer a

Animal models have demonstrated a link between decreases in retinal dopamine levels and the development of form-deprivation myopia (FDM). However, the consistency of dopamine's role in the other major form of experimental myopia, that of lens-induced myopia (LIM), is less

An imbalance in dopamine-mediated neurotransmission is a hallmark physiological feature of neuropsychiatric disorders, such as schizophrenia. Recent evidence demonstrates that dopamine D(2) receptors, which are the main target of antipsychotics, modulate the activity of the protein kinase Akt, which is

Findings have shown that anterior insular cortex (aIC) lesions disrupt the maintenance of drug addiction, while imaging studies suggest that connections between amygdala and aIC participate in drug-seeking. However, the role of the BLA → aIC pathway in rewarding contextual memory has

SCH 23390 [R-(+)-8-chloro-2,3,4,5-tetrahydro-3-methyl-5-phenyl-1H-3-benzazepine-7-ol) possesses pharmacologic effects similar to standard antipsychotics, including selective supression of conditioned avoidance responding in rats and squirrel monkeys, blockade of apomorphine-induced stereotypy in rats and blockade of methamphetamine-induced lethality in aggregated mice. At effective doses in

In the vocal learning model, the juvenile first memorizes a model sound, and the imprinted memory gradually converts into vocal-motor output during the sensorimotor integration. However, early acquired memory may not precisely represent the fine structures of a model sound.

A series of 1-phenyl-1H-3-benzazepine analogues were assessed for enantiomeric and structure-affinity relationships at human putamen D-1 dopamine receptors labelled with [3H]SCH 23390. Substitution at the 7-position of both 3-H and 3-methyl benzazepine molecules critically affected affinity for these receptors over
