Hello Lara; A brief review can be found in Science Magazine, 365(6458): 1087. 13 Sept. 2019. Best regards, Jim Des Lauriers

Many years ago, Morgan (1894) proposed that "In no case is an animal activity to be interpreted in terms of higher psychological processes if it can be fairly interpreted in terms of processes which stand lower in the scale of psychological evolution and development." The application of Morgan’s Canon to research on comparative cognition is not intended as insistence on a simplistic interpretation of all behavior; it is intended to inquire whether the cognitive interpretation is necessary. When used appropriately, it is meant to encourage researchers to think of simpler explanations and by so doing, to consider how one would test the hypothesis that the simpler explanation is not adequate to account for the observed results. The process of ruling out alternative explanations for behavior is especially difficult when attempting to assess the emotions of an animal, but if we are to progress in our understanding of animal behavior, it is particularly important to heed Morgan’s advice.

Hi Lara,

In a paper about 25 years ago, german neurobiologists recorded in honey bees brain surface evoked electrical potentials similar to dream activity in mamals.

There are also quitre lot of work done in isnects concerning sleeping activity (e.g. The Journal of Experimental Biology 211, 2408-2416 , Differences in the sleep architecture of forager and young honeybees (Apis mellifera) in which you may find soem reference).

There is also some work done in gustation (insects) about hedonic perception (in flies and bees). My colleague Frederic Marion Poll (he is on RG) did some experiments withe the hedonic perception in Drosophila.

Do not know if it helps

Regards,

Denis Thiery
