 Project objective

Memory formation and extinction are fascinating aspects of brain functions. Observation of ex vivo and in vitro experiments provided a framework for understanding associative memory-related plasticity. However, memories are generated via local neuronal interactions within the context of their global networks, and understanding their formation requires in vivo studies in naturalistic conditions, which remain technically challenging. Here, I will use a functional calcium imaging approach to investigate memory formation and extinction in behaving honeybees. I will adopt the honeybee as a model system because of the accumulated knowledge on associative learning, the availability of a behavioural read-out for both appetitive and aversive memory formation, and its robustness, which allows for long-lasting imaging experiments. I will focus on its olfactory system because of the optical accessibility, and its analogy with the vertebrate one. Previous works have established the methods for honeybee brain imaging analysis in vivo during appetitive and aversive conditioning. Within this project, I will perform long-term imaging experiments in behaving animals, while monitoring the process of short and long-term memory formation and extinction in the three main neuropils of the olfactory system: the antennal lobe (the primary odour processing centre), the mushroom bodies (possibly dedicated to odour recognition), and the lateral horn (involved in odour valence evaluation). My specific goals are (1) characterizing the morphological and functional changes induced by associative learning throughout these neuropils, (2) highlighting the functional dynamics of a stimulus representation during short and long-term memory formation and extinction, and (3) comparing the memory engram of positive and negative associations. This project will provide important insight on the neural correlates of memory formation and extinction in a behaving animal.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "MEM-ENTO" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
