Effects of dopamine on neurons of the lateral geniculate nucleus: An iontophoretic study

Distribution of Dopamine D3 Receptor Expressing Neurons in the Human Forebrain Comparison with D2 Receptor Expressing Neurons

“…Recent data have indicated the presence of dopaminergic fibers (Papadopoulus and Parnavelas 1990) and DA receptors (Bouthenet et al 1987;Huang et al 1992) in the rat LGB, and D 3 receptor mRNA in the human LGB (Suzuki et al 1998). In the rat, neurons of the LGB respond to application of D 2 agonists by increased baseline activity, an effect that was reversible by specific D 2 antagonists (Albrecht et al 1996). In both nuclei D 3 and D 2 mRNA co-localize to a considerable proportion of neurons in magnocellular laminae 1 and 2, whereas in upper laminae D 2 mRNA positive neurons predominate.…”

The Effects of Selective Serotonin-Reuptake Inhibitor on Visual Evoked Potential in Rats

“…In addition, the drug also showed a release of dopamine in the central nervous. Albrech et al (11) reported that dopamine has similar behavior as 5-HT in the neurons of the lateral geniculate nucleus. It is generally recognized that VEP is thought to be generated in the visual cortex (12,13).…”

Visual contrast sensitivity in school-age Guadeloupean children exposed to chlordecone

“…For instance, impaired contrast sensitivity has been found in pharmacological studies using drugs that alter GABAergic transmission, while visual acuity remained relatively intact (Blin et al, 1993;Haris and Phillipson, 1995;Giersch et al, 2006). Dopamine is another important neuromodulator of visual processing at both retinal and cortical levels (Albrecht, Quaschling, Zippel, & Davidowa, 1996;Parkinson, 1989;Witkovsky & Schutte, 1991). An improvement in contrast sensitivity has been demonstrated following administration of dopaminergic agonists in humans (Bulens, Meerwaldt, Van der Wildt, & Van Deursen, 1987;Domenici, Trimarchi, Piccolino, Fiorentini, & Maffei, 1985).…”
