The mechanisms involved in the food perception and selection remain poorly explored in many invertebrates including Drosophila melanogaster. Although our knowledge on these processes has rapidly increased, less is known about the mechanism of deciding or changing in the food preferences of Drosophila. This study explores how the type of media in Drosophila food affect male and female Drosophila...
The effect of long-term feeding on Bt-maize by collembolans in the laboratory is virtually unestablished. That is why the aim of the present study was to test whether the reproduction, fecal pellet production or food preference of the collembolan F. candida is affected when fed on Bt-maize for several consecutive generations. The collembolans were fed with Bt-maize for 0, 6, 16 and 22 months an...
An elderly female developed anarthria with prominent emotionality over an 18month period before specialist neurological assessment. Although tongue electromyography was normal, her corticobulbar signs were consistent with amyotrophic lateral sclerosis (ALS), a pattern that, in the absence of functional impairment outside of speech and swallowing, is appropriately termed progressive bulbar palsy...
Food preference is best understood as the interaction between taste and postingestive feedback, determined by an animal's physiological condition and to a food's chemical characteristics. Taste (as well as smell and sight) enables animals to discriminate among foods and provides hedonic sensations associated with eating. Postingestive feedback calibrates taste in accord with a food's homeostati...
Many animals have the ability to acquire food preferences from conspecifics via social signals. For example, the coincident detection of a food odor by canonical olfactory sensory neurons (OSNs) and agonists of the specialized OSNs expressing the receptor guanylyl cyclase GC-D (GC-D+ OSNs) will promote a preference in recipient rodents for similarly odored foods. It has been hypothesized that t...
Objective: The impact of different weaning methods on food preferences and body mass index (BMI) in early childhood is not known. Here, we examine if weaning methoddbaby-led weaning versus traditional spoon feedingdinfluences food preferences and health-related outcomes. Design, setting and participants: Parents (n1⁄4155) recruited through the Nottingham Toddler laboratory and relevant internet...
The Otsuka Long-Evans Tokushima Fatty (OLETF) rat, an outbred strain of Long- Evans Tokushima Otsuka rat (LETO) that lacks CCK-1 receptor expression, is hyperphagic and develops obesity and type-2 diabetes. The present study sought to assess how OLETF rats alter intake, preference, and conditioned preference of palatable solutions after acute food deprivation. Our results show that after 24 h c...
One of the key tasks in the study of the recommendation system is to model the dynamics aspect of a person’s preference, i.e. to give sequential recommendations. Markov Chain (MC), which is famous for its capability of learning a transition graph, is the most popular approach to address the task. In previous work, the recommendation system attempts to model the short-term dynamics of the person...
