Description:
Converging evidence from human lesion, animal lesion, and human functional neuroimaging studies implicates overlapping neural circuitry in ventral prefrontal cortex in decision-making and reversal learning. The ascending 5-HT and dopamine neurotransmitter systems have a modulatory role in both processes. There is accumulating evidence that measures of decision-making and reversal learning may be useful as functional markers of ventral prefrontal cortex integrity in psychiatric and neurological disorders. Whilst existing measures of decision-making may have superior sensitivity, reversal learning may offer superior selectivity, particularly within prefrontal cortex. Effective decision-making on existing measures requires the ability to adapt behaviour on the basis of changes in emotional significance, and this may underlie the shared neural circuitry with reversal learning.

Bard PerFix Plug, Small, 1.0" x 1.35", 6/Bx
$4,590.00
The Bard PerFix plug technique, recommended for the treatment of all primary and recurrent indirect and direct inguinal hernias, provides significant advantages over a conventional suture technique, requiring less overall dissection and is utilized in a complete tension-free" repair technique. The result is increased patient comfort, fast rehabilitation, and fewer recurrences. The entire operation can take 25 minutes or less.* In addition, the technique offers significant time and cost-saving benefits. The tapered shape of the PerFix plug eases insertion into the hernia defect, while the pre-shaped onlay patch accommodates the anatomy of the inguinal canal. This ready-to-use plug design minimizes any need to tailor perioperatively. The entire operation takes less time from incision to dressing placement. Technical simplicity means general anesthesia is not required. Features and Benefits: Patients have far less pain. Virtually eliminates recurrence. Constructed of same monofilament polypropylene. PerFix plug remains invert in the presence of infection, and promotes tissue ingrowth. Surgery with the Bard PerFix plug requires less operating and recovery time, procedures can be exceptionally cost-effective. Size Small: 1.0" x 1.35" (2.5cm x 3.4cm). Each PerFix plug comes with a standard size, pre-shaped onlay patch measuring 1.80" (4.6cm) by 3.5" (8.9cm). The product referenced on this detail page is sold be 6/Bx.

Description:
Visual object perception is usually studied by presenting one object at a time at the fovea. However, the world around us is composed of multiple objects. The way our visual system deals with this complexity has remained controversial in the literature. Some models claim that the ventral pathway, a set of visual cortical areas responsible for object recognition, can process only one or very few objects at a time without ambiguity. Other models argue in favor of a massively parallel processing of objects in a scene. Recent experiments in monkeys have provided important data about this issue. The ventral pathway seems to be able to perform complex analyses on several objects simultaneously, but only during a short time period. Subsequently only one or very few objects are explicitly selected and consciously perceived. Here, we survey the implications of these new findings for our understanding of object processing.
