Mesencephalon - Physiopathology
Research News and Information
Definition of 'Mesencephalon'The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, constricted portion connecting the PONS and the DIENCEPHALON. Midbrain contains two major parts, the dorsal TECTUM MESENCEPHALI and the ventral TEGMENTUM MESENCEPHALI, housing components of auditory, visual, and other sensorimoter systems. Common names: Mesencephalon; Mesencephalons; Midbrain; Midbrains |

Age dependent nicotinic influences over dopamine neuron synaptic plasticity.
19 May 2009 
The dopamine (DA) system of the ventral midbrain plays a critical role as mammals learn adaptive behaviors driven by environmental salience and reward. Addictive drugs, including nicotine, exert powerful influences over the mesolimbic DA system by ... Read more...
Dopaminergic response to drug words in cocaine addiction.
4 May 2009 When exposed to drug conditioned cues (stimuli associated with the drug), addicted individuals experience an intense desire for the drug, which is associated with increased dopamine cell firing. We hypothesized that drug-related words can trigger ... Read more...
Evidence for metabolic hypothalamo-amygdala dysfunction in narcolepsy.
29 Apr 2009 STUDY OBJECTIVES: Proton resonance spectroscopy (1H-MRS) allows noninvasive chemical tissue analysis in the living brain. As neuronal loss and gliosis have been described in narcolepsy, metabolites of primary interest are N-acetylaspartate (NAA), a ... Read more...
