Using dual-site calcium imaging to evaluate coordination of task relevant spatial representations in hippocampus and cingulate cortex
How do different brain regions interact to support complex cognitive functions? This webinar will showcase novel methodology for performing dual-site MiniScope recordings of calcium activity from neuronal ensembles in the hippocampus and cingulate cortex as rats perform a spatial cognitive control task. We'll also discuss the development of a dual-MiniScope cable commutator, building upon our existing multi-purpose commutators, enabling tangle-free recordings during this freely-behaving task.
Garrett Blair is a postdoc in Dr. André Fenton's lab, having earned his PhD in Psychology from UCLA (‘21) where he pioneered the application of calcium imaging in the hippocampus (Blair et al. eLife 2023; Guo, Blair et al. Sci. Adv. 2023) and anterior cingulate cortex (Hart, Blair et al. JNeuro. 2020) of freely behaving rats. Today, Garrett is studying how the hippocampus and cingulate cortex collectively represent task-relevant information by recording from both regions during a spatial navigation task.
