2 days ago · Gating of hippocampal-evoked activity in prefrontal cortical neurons by inputs from the mediodorsal thalamus and ventral tegmental area. J Neurosci. 2003;23:3930–43.
5 days ago · The striatum (a collective term for the caudate nucleus and putamen; see Figure 38–1), subthalamic nucleus, and substantia nigra pars compacta/ventral tegmental area are the three major input nuclei of the basal ganglia, receiving signals directly and indirectly from structures distributed throughout the neuraxis (Figure 38–2).
3 days ago · Mid-ventral medial prefrontal cortex: Cognitive processes: Coping with empathic distress: Dorsal medial prefrontal cortex/inferior frontal cortex: Emotion regulation: Feeling warmth/tenderness towards others: Periacqueductal gray, substantia nigra, and ventral tegmental area: Phenomenal feeling: Overarching motivation to approach

4 days ago · From the standpoint of future treatments in patients with severe brain injuries, the researchers showed that a dopamine-producing region in the brainstem, the ventral tegmental area, is a connectivity hub that links the subcortical default ascending arousal network to the cortical default mode network.
3 days ago · Both responses could be reliably induced. By optogenetic and chemogenetic methods, a neural pathway was discovered, with elevated dopamine levels in the ventral tegmental area and the striatum, where distinct subregions encode different kinds of expectations.
3 days ago · Lidocaine was infused into the ventral tegmental area, the site of dopamine cell bodies, to arrest neuronal firing. While there was virtually no instantaneous change in dopamine concn., longer sampling revealed a decrease in dopamine transients and a time-averaged decrease in the extracellular level.
