Lateral NAc Shell D1 and D2 Neuronal Ensembles Concurrently Predict Licking Behavior and Categorize Sucrose Concentrations in a Context-dependent Manner.

The palatability and concentration of sweet foods promote hedonic feeding beyond homeostatic need. Understanding how neurons respond to sweet taste is thus of great importance. The dorsomedial nucleus accumbens shell (dNAcMed) is considered a "sensory sentinel," promoting hedonic feeding.

Kinematic fundamentals of a biomechatronic laparoscopy system.

Background: Optical assistance in laparoscopic surgery is essential for an optimal procedure. Unlike conventional surgery, it requires new systems to reduce spatial location time, navigation and cleanliness without compromising surgical quality. This article shows the kinematic analysis of a new bio-mechatronic design to assist laparoscopic visual perspective in real time, either during training or in surgery.
