Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The autonomic nervous system (ANS) controls the activity of the body's internal organs and regulates changes in their activity depending on the current environment. The vagus nerve, which innervates many of the internal organs, is an important part of the system. When our brain senses danger, vagal tone is inhibited, leading to a set of changes in the body designed to make us more prepared to fight or...

2025
By pairing negatively or positively valenced experiences with individual social targets, we developed behavior tasks for examining the identity recognition of C57BL/6 mice. These tasks allow for the study of mechanisms of social memory of individual social targets in healthy and disease-related mouse models with impaired social cognition.

Zebrafish are emerging as a valuable model of dietary lipid processing and metabolic disease. Described are protocols of lipid-rich larval feeds, live imaging of dietary fluorescent lipid analogs, and quantification of food intake. These techniques can be applied to a variety of screening, imaging, and hypothesis driven inquiry techniques.
FAQs
Convolutional neural networks process image pixels to identify visual features associated with food. Their analysis can emphasize characteristics such as color, texture, and shape, allowing a model to distinguish among foods or ingredients after learning from labeled training data. In engineering applications, this feature extraction supports automated analysis instead of requiring every image to be interpreted manually.
A system may either classify the food content of an image or locate multiple items within the same image. Classification assigns food-related categories, whereas locating items addresses where different foods appear in the image. This distinction matters for mixed meals and food inventory or restaurant systems, where recognizing several components can be more useful than assigning one overall label.
Mixed dishes, occlusion, variable lighting, and uncertain portion size can all reduce the reliability of food image recognition. Occlusion hides visual evidence, lighting changes the appearance of color and texture, and mixed dishes make separate identification difficult. These conditions guide improvements in dataset design, model accuracy, and practical deployment rather than representing only software concerns.
Development begins with labeled food images that provide examples for machine-learning training. A model then learns visual features from the image pixels and is used to classify foods or locate multiple items. Engineers evaluate the resulting recognition performance under practical conditions, including mixed dishes, occlusion, and variable lighting, before considering deployment in an application.
Supported applications include dietary assessment, nutrition tracking, food inventory, quality inspection, and restaurant automation. The same recognition capability can therefore serve consumer-facing tracking tools as well as operational systems that examine food items. The appropriate application depends on whether the system needs food identification, analysis of several items, or automated inspection within a larger engineered workflow.
It can identify foods, ingredients, or meal components and may support analysis of multiple items in one image. However, recognizing a food does not automatically resolve its portion size, especially when visual evidence is obscured or dishes are mixed. This limitation is important for dietary assessment and nutrition tracking, where practical usefulness depends on both identification and reliable interpretation.
