Rapid use-dependent down-regulation of gamma-aminobutyric acid type A receptors in rat mesencephalic trigeminal neurons.

30 Oct 2009 Rundown is ubiquitously seen in response to repetitive activation of receptor or ion channels as a use-dependent down-regulation through various mechanisms. In contrast to AMPA receptors, gamma-aminobutyric acid type A receptor (GABA(A)R) are ... Read more...

Differential corticosteroid receptor regulation of mesoaccumbens dopamine efflux during the peak and nadir of the circadian rhythm: a molecular equilibrium in the midbrain?

30 Oct 2009 Corticosteroid receptor modulation of mesoaccumbens dopamine neurotransmission is believed to be a key neurobiological mechanism mediating the effects of stress in addiction. Importantly, nucleus accumbens (NAc) subregions (core and shell) are ... Read more...

Meis2 competes with the Groucho co-repressor Tle4 for binding to Otx2 and specifies tectal fate without induction of a secondary midbrain-hindbrain boundary organizer.

29 Sep 2009 The transcription factor Otx2 is expressed throughout the anterior neuroectoderm and is required for the formation of all forebrain- and midbrain-derived structures. The molecular determinants that cooperate with Otx2 to subdivide its expression ... Read more...

Technical information about 'Mesencephalon'

Definition: 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.
