Tracking rats’ vocal responses to palatable food

Caption

The researchers wanted a more direct, non-invasive way to assess how much an animal enjoys food, beyond simply measuring food intake. While recording rats during chocolate feeding, they noticed that the rats produced a characteristic vocalization while eating. This led them to investigate whether these calls carried information about how much they enjoyed the food.
