Dopamine and the regulation of cognition and attention.
Nieoullon A. Nieoullon A. Prog Neurobiol. 2002 May;67(1):53-83. doi: 10.1016/s0301-0082(02)00011-4. Prog Neurobiol. 2002. PMID: 12126656 Review.
Dopamine (DA) acts as a key neurotransmitter in the brain. Numerous studies have shown its regulatory role for motor and limbic functions. ...This point is still a matter of debate but, undoubtedly, DA acts as a powerful regulator of different aspects of cogn …

Quantitative behavioral study of the acute and long-term effects of two-stage bilateral 6-OHDA-induced lesions of the nigrostriatal dopaminergic system in monkeys.
Apicella P, Legallet E, Nieoullon A, Trouche E. Apicella P, et al. Behav Neurosci. 1995 Apr;109(2):329-41. doi: 10.1037//0735-7044.109.2.329. Behav Neurosci. 1995. PMID: 7619323
Several months after a unilateral nigrostriatal damage, a lesion on the other side produced impairments only on the side of the body contralateral to that second lesion and did not reinstate the deficits on the side previously affected by the first lesion. This sugg …
