1 It has been hypothesized that craniovascular 5-HT receptors mediating dilatation of cranial vessels undergo sensitization on decreased serotonergic transmission in migraine. This study analysed the effect of chemical lesion of the 5-HT system in the brain with 5,7-dihydroxytryptamine (5,7-DHT) on 5-HT receptor-mediated dilator responses to(More)
Low brain serotonin levels and high circulating levels of corticosterone are features of migraine. The 5-HT7 receptor was shown to mediate dilator responses to the 5-HT1B/1D and 5-HT7 receptor agonist, 5-carboxamidotryptamine in the middle meningeal artery of rats. Here we analyzed the effect of serotonin depletion and chronic corticosterone treatment on(More)
This work presents a search planning system for a rolling robot to find a source of infra-red (IR) radiation at an unknown location. Heat emissions are observed by a low-cost home-made IR passive visual sensor. The sensor capability for detection of radiation spectra was experimentally characterized. The sensor data were modeled by an exponential model to(More)
In this paper design, integration and functional evaluation of reconfigurable Klann based four legged robot platform is reported. Here a four legged platform generating six useful gaits is implemented. The design process, mechanical assembly, electronic control and transformation mechanism for various scenarios is reported. The designed platform is able to(More)
One of the key benefits of reconfigurable legged robots is their ability to move in a non-continuous way enabling it to provide better mobility over rough and irregular terrains. Legged robots should maintain it stability during rest and motion with minimum number of legs while maintaining its functionality during various gait generation and its resultant(More)
