The neural processing of taste

Although there have been many recent advances in the field of gustatory neurobiology, our knowledge of how the nervous system is organized to process information about taste is still far from complete. Many studies on this topic have focused on understanding how gustatory neural circuits are spatially organized to represent information about taste quality (e.g., "sweet", "salty", "bitter", etc.). Arguments pertaining to this issue have largely centered on whether taste is carried by dedicated neural channels or a pattern of activity across a neural population. But there is now mounting evidence that the timing of neural events may also importantly contribute to the representation of taste. In this review, we attempt to summarize recent findings in the field that pertain to these issues. Both space and time are variables likely related to the mechanism of the gustatory neural code: information about taste appears to reside in spatial and temporal patterns of activation in gustatory neurons. What is more, the organization of the taste network in the brain would suggest that the parameters of space and time extend to the neural processing of gustatory information on a much grander scale

Socioecology of the canine population in the province of El Jadida, Morocco

Understanding the socioecology of domestic dog populations is essential for effective disease control, especially canine rabies. In Morocco, since 1986, the control efforts and plans put in place by the government have failed to eradicate this disease; this is because the management of the canine population was not taken into account during the establishment of these plans. It is against the background that this study was designed to estimate the dog population and determine its socioecological characteristics, as well as investigate the attitude of the inhabitants towards the dogs. A stratified random sampling was conducted using a structured questionnaire from May to December 2016. A total of 1931 households were interviewed, comprising 27.4% in urban areas and 72.6% in rural areas. A total of 3719 dogs were counted alongside a human population of 11302 for a dog : human ratio of 1 : 2.42 in rural areas and 1 : 46.58 in urban areas. The majority of dogs (92%) in rural areas were not vaccinated against rabies. In urban areas, about 88.5% were vaccinated against rabies. In addition, 78.5% of dogs in rural areas were free roaming, with more than 53% of births being abandoned by their owners, resulting in a large stray and feral dog population and increasing the potential for continued transmission of rabies virus. There was strong association between breed and rabies vaccination (
