Excessive release of inflammatory/pain mediators from peripheral sensory afferents renders nerve endings hyper-responsive, causing central sensitization and chronic pain. Herein, the basal release of proinflammatory calcitonin gene-related peptide (CGRP) was shown to increase the excitability of trigeminal sensory neurons in brainstem slices via CGRP1(More)
Paraganglia resembling the carotid body have been described in the superior laryngeal nerve (SLN) of the rat and the aim of the present study was to determine if this tissue is chemosensitive. We developed a novel isolated SLN preparation superfused with HEPES-buffered Tyrode solution at 35 degrees C in vitro. A glass suction microelectrode was used to(More)
Image segmentation can be viewed as the process of classifying regions in a picture into groups with common properties (e.g., texture). A difficulty arising is that a common texture can be classified differently when viewed at different scales and rotated viewpoints. The paper presents a feature vector based on the DT-CWT (dual-tree complex wavelet(More)
Pro-inflammatory cytokines are known to be elevated in several neuropathological states that are associated with learning and memory impairments. We have previously demonstrated the inhibition of long-term potentiation (LTP), a recognised model for memory, in the dentate gyrus region of the rat hippocampus, by interleukin-18. We have also previously shown(More)
Widespread use of digital imagery has resulted in a need to manage large collections of images. Systems providing query by example (QBE) capability offer improved access to contents of image libraries by retrieving matches to a query image. Texture is an important feature to consider in the matching process. However, standard approaches often employ a(More)
The reliance of many video processing techniques on motion estimation requires a good motion confidence measure, in order to ensure that unreliable estimations are not accepted into a system. This paper proposes a new measure of motion confidence based on phase information from Fourier transform of a video frame. Using the measure, blocks associated with(More)
We investigate the problem of robust video transmission over packet loss networks. A resilient video coding framework is important to ensure quality video over these networks. We propose a combination of multiple description coding and an optimized packetization method to constitute the error resilient codec. Multiple description coding technique utilizes(More)
In this paper, we propose some extensions of an efficient gradient-based image registration method called the inverse compositional algorithm. Specifically, these extensions include cumulative multi-image registration and incorporations of illumination change and lens distortion correction. By combining these extensions, we propose efficient cumulative(More)
