- Chemical stimulation of the ventral hippocampus elevates nucleus accumbens dopamine by activating dopaminergic neurons of the ventral tegmental areaM Legault
Center for Studies in Behavioral Neurobiology, Department of Psychology, Concordia University, Montreal, H3G 1M8 Quebec, Canada
J Neurosci 20:1635-42. 2000..The results of the present experiments identify the VTA as a critical site through which outputs from the VS modulate NAS dopaminergic neurotransmission...
- Novelty-evoked elevations of nucleus accumbens dopamine: dependence on impulse flow from the ventral subiculum and glutamatergic neurotransmission in the ventral tegmental areaM Legault
Center for Studies in Behavioural Neurobiology, Department of Psychology, Concordia University, Montreal, Quebec, Canada, H3G 1M8
Eur J Neurosci 13:819-28. 2001..These data indicate that phasic elevations in nucleus accumbens dopamine evoked by exposure to unconditioned novel stimuli are dependent on impulse flow from the hippocampus and glutamatergic transmission in the VTA...
- Injections of N-methyl-D-aspartate into the ventral hippocampus increase extracellular dopamine in the ventral tegmental area and nucleus accumbensM Legault
Center for Studies in Behavioral Neurobiology, Concordia University, Montreal, Quebec, Canada
Synapse 31:241-9. 1999..Thus, the present study suggests that the modulation of dopaminergic neurotransmission by the ventral subiculum results from a trans-synaptic activation of dopamine cell bodies in the VTA...
- Presynaptic action of neurotensin on cultured ventral tegmental area dopaminergic neuronesM Legault
Départements de pharmacologie et de psychiatrie, Centre de Recherche en Sciences Neurologiques, Centre de Recherche Fernand Seguin, Universite de Montreal, Montreal, QC, Canada
Neuroscience 111:177-87. 2002..The main effect of neurotensin on nerve terminals is not to produce a direct excitation, but rather to decrease the effectiveness of D2 receptor-mediated presynaptic inhibition...
