Characterization of dopaminergic projections from the ventral tegmental area and the dorsal raphe nucleus to the orbital frontal cortex.

The orbitofrontal cortex (OFC) is a key node in the cortico-limbic-striatal circuitry that influences decision-making guided by the relative value of outcomes. Midbrain dopamine from either the ventral tegmental area (VTA) or the dorsal raphe nucleus (DRN) has the potential to modulate OFC neurons; however, it is unknown at what concentrations these terminals release dopamine. Male and female adult dopamine transporter (DAT)-tdTomato mice were injected with AAV2/8-EF1a-DIO-eYFP into either the DRN or the VTA or the retrograde label cholera toxin B (CTB) 488 in the medial or lateral OFC.

Short- and Long-Term High-Fat Diet Exposure Differentially Alters Phasic and Tonic GABAergic Signaling onto Lateral Orbitofrontal Pyramidal Neurons.

The chronic consumption of caloric dense high-fat foods is a major contributor to increased body weight, obesity, and other chronic health conditions. The orbitofrontal cortex (OFC) is critical in guiding decisions about food intake and is altered with diet-induced obesity. Obese rodents have altered morphologic and synaptic electrophysiological properties in the lateral orbitofrontal cortex (lOFC).

Crystal structures of three substituted 3-aryl-2-phenyl-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-ones.

Three ring-substituted 3-aryl analogs of 2-phenyl-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-one, namely 3-(4-meth-oxy-phen-yl)-2-phenyl-4H-1,3-benzo-thia-zin-4-one, C21H17NO2S, (I), 2-phenyl-3-[4-(tri-fluoro-meth-yl)phen-yl]-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-one toluene hemisolvate, C21H14F3NOS·0.5C7H8, (II), and 3-(3-bromo-phen-yl)-2-phenyl-2,3-di-hydro-4H-1,3-benzo-thia-zin-4-one toluene hemisolvate, C20H14BrNOS·0.5C7H8, (III), were synthesized and their crystal structures determined.
