While non-caloric artificial sweeteners (NAS) are used as food additives, it’s unclear whether animals perceive NAS as positive or negative percept. Here, Musso and colleagues show in Drosophila that NAS is a negative percept, encoded in a new type

How does the concerted activity of neuronal populations shape behavior? Impediments to address this question are primarily due to critical experimental barriers. An integrated perspective on large scale neural information processing requires an in vi

Delayed Dopamine Signaling of Energy Level Builds Appetitive Long-Term Memory in Drosophila

Autor: Paul Tchénio, Thomas Preat, Pierre-Yves Musso

Publikováno v: Cell Reports, Vol 10, Iss 7, Pp 1023-1031 (2015)

SummarySensory cues relevant to a food source, such as odors, can be associated with post-ingestion signals related either to food energetic value or toxicity. Despite numerous behavioral studies, a global understanding of the mechanisms underlying t

Fluorescence in situ hybridization (ISH) could be a powerful tool for analyzing the dynamics of memory phases if a semi-quantitative measurement of mRNA levels could be performed with a cellular resolution. While such a method does not yet exist, we

Recently, different approaches have been implemented to detect single molecules with an optical dipole out of the sample plane. Principles to solve this problem of general interest have been laid but no detailed analysis has been performed to date. T
