OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Oscillation in Physiology: the How and the Why
Please note change of series location to Sherrington Library
The concept of equilibrium is powerful and long dominant in the sciences; in physiology, the equilibrium paradigm is embodied in the principle of homeostasis, an equilibrium state that is enforced by negative feedback loops. But physiological quantities are, in fact, not in static equilibrium. Oscillation is another critical form of behavior, seen in both normal physiology and in pathophysiology.
We will review examples of oscillation in normal physiology: gene expression, embryology, hormone regulation, neuronal bursting. We will focus on how mathematical modeling can isolate and identify the mechanisms responsible for the oscillatory behavior.
We will also discuss the why of oscillation: what is the functional role, if any, of these oscillatory processes?
There are also a number of examples of pathological oscillation in physiology and medicine, ranging from muscle tremors to cardiac early-afterdepolarizations to ventricular fibrillation to punctate patterning in arterial calcification. In these cases, mathematical modeling shows us how to design therapeutic interventions and develop new categories of pharmacology.
