This thesis examines the impact of polymorphisms in SLC6A4 and CYP450 on SSRI pharmacodynamics and pharmacokinetics, explores their potential for guiding personalized antidepressant therapy, and discusses the ethical and practical …

A Two-Phase Hippocampal Code Linking Time And Distance Estimation To Action, Raphael Heldman

Electronic Theses and Dissertations 2020 - Present

A critical component of spatial navigation is the ability to estimate elapsed time or distance traveled. How the brain generates such estimates and links them to behavior remains unclear. In this thesis, we identify a previously unrecognized population coding strategy for time or distance in hippocampal CA1, a region critical for navigation and memory. Using novel behavioral paradigms in head-fixed mice combined with electrophysiological recordings, we show that this code is carried by two functionally distinct subpopulations of pyramidal neurons, termed PyrUp and PyrDown, whose firing rates evolve in opposite directions during navigation. Both populations exhibit a common two-phase dynamic: …
