The Response of Ventral Tegmental Area Dopaminergic Neurons to Bupropion: Excitation or Inhibition?

Introduction: Antidepressants can modulate brain monoamines by acting on pre-synaptic and postsynaptic receptors. Autoreceptors can reduce the monoamines effect on the somatodendritic or pre-synaptic regions despite its postsynaptic counter effects. The direct effect of some antidepressants is related to its temporal and spatial bioavailability in the vicinity of these receptors (still a matter...

Characterization of M-current in ventral tegmental area dopamine neurons.

M-current (I(M)) is a voltage-gated potassium current (KCNQ type) that affects neuronal excitability and is modulated by some drugs of abuse. Ventral tegmental area (VTA) dopamine (DA) neurons are important for the reinforcing effects of drugs of abuse. Therefore we studied I(M) in acutely dissociated rat DA VTA neurons with nystatin-perforated patch recording. The standard deactivation protoco...

Neurotensin inhibits both dopamine- and GABA-mediated inhibition of ventral tegmental area dopamine neurons.

Dopamine is an essential neurotransmitter that plays an important role in a number of different physiological processes and disorders. There is substantial evidence that the neuropeptide neurotensin interacts with the mesolimbic dopamine system and can regulate dopamine neuron activity. In these studies we have used whole cell patch-clamp electrophysiology in brain slices from mice to examine h...

Neurotensin inhibits both dopamine and GABA mediated inhibition of ventral tegmental 1 area dopamine neurons

26 Dopamine is an essential neurotransmitter that plays an important role in a number of 27 different physiological processes and disorders. There is substantial evidence that the 28 neuropeptide neurotensin interacts with the mesolimbic dopamine system and can regulate 29 dopamine neuron activity. In these studies we have used whole-cell patch clamp 30 electrophysiology in brain slices from mi...

Ethanol Blocks the Reversal of Prolonged Dopamine Inhibition of Dopaminergic Neurons of the Ventral Tegmental Area

Drug abuse-induced plasticity of putative dopaminergic (pDAergic) ventral tegmental area (VTA) neurons may play an important role in changes in the mesocorticolimbic system that lead to the development of addiction. In the present study, extracellular recordings were used to examine time-dependent effects of dopamine (DA) on pDAergic VTA neurons in rat brain slices. Administration of DA (2.5-10...
