BACKGROUND: Intravenous regional anaesthesia is a simple, safe and effective technique with good success rate for upper limb surgeries. The duration of postoperative analgesia is an important limitation of this technique. Various adjuvants have been used to overcome this drawback. In this study we evaluate the effect of dexmedetomidine 0.5 μgkg(-1) as an adjuvant for lignocaine intravenous regional anaesthesia. METHODS: Sixty patients scheduled to undergo upper limb surgery were randomised to receive intravenous regional anaesthesia with lignocaine alone (Group L) or lignocaine with dexmedetomidine 0...

Sensory gating is a preattentional mechanism to filter irrelevant information from the environment. It is typically reflected as a suppression of the event-related P50 component for successive sounds in the auditory modality. Although stress-induced sympathetic activation has been reported to disrupt P50 suppression, little is known about the modulatory effect of parasympathetic activation on early auditory sensory gating. We determined the parasympathetic effect on the magnetic P50 (P50m) suppression by controlling the respiratory rhythm and recording data simultaneously with magnetoencephalography and electrocardiography, using three successive click sounds as stimulus and ten normal individuals as study participants...

The capability of perceiving olive oils sensory defects and intensities plays a key role on olive oils quality grade classification since olive oils can only be classified as extra-virgin if no defect can be perceived by a human trained sensory panel. Otherwise, olive oils may be classified as virgin or lampante depending on the median intensity of the defect predominantly perceived and on the physicochemical levels. However, sensory analysis is time-consuming and requires an official sensory panel, which can only evaluate a low number of samples per day...

How complex is the memory structure that honeybees use to navigate? Recently, an insect-inspired parsimonious spiking neural network model was proposed that enabled simulated ground-moving agents to follow learned routes. We adapted this model to flying insects and evaluate the route following performance in three different worlds with gradually decreasing object density. In addition, we propose an extension to the model to enable the model to associate sensory input with a behavioral context, such as foraging or homing...
