Siamo lieti di annunciare che Giorgio Cuzzola, nostro ex studente di Neurobiologia, è tra i dieci finalisti del Premio Nazionale di Divulgazione Scientifica Giancarlo Dosi 2019 sezione video. Giorgio si è laureato con lode in neurobiologia nella sessione di ottobre, e da oltre un anno realizza video di divulgazione scientifica per ragazzi, spaziando tra la biologia e le neuroscienze. Nel suo ultimo video, ad esempio, spiega il funzionamento semplificato della memoria,…

Animals rely on the relative timing of events in their environment to form and update predictive associations, but the molecular and circuit mechanisms for this temporal sensitivity remain incompletely understood. Here, the auhtors show that olfactory associations in Drosophila can be written and reversed on a trial-by-trial basis depending on the temporal relationship between an odor cue and dopaminergic reinforcement. Through the synchronous recording of neural activity and behavior, the authors…

Widefield imaging of calcium dynamics is an emerging method for mapping regional neural activity but is currently limited to restrained animals. Here Scott and collegues describe cScope, a head-mounted widefield macroscope developed to image large-scale cortical dynamics in rats during natural behavior. cScope provides a 7.8 × 4 mm field of view and dual illumination paths for both fluorescence and hemodynamic correction and can be fabricated at low cost using readily…
