HodgkinHuxley models and Markov equivalents
Hodgkin & Huxley did some incredible work in the 1930s50s on ion currents flowing through biological membranes. Despite not knowing what an ion channel was, they managed to work out an incredibly accurate predictive mathematical model for the currents that … Continue reading

Short and rich voltageclamp protocols
This is a quick post to tell you all about Kylie’s new paper on sinusoidalwave based voltage clamp protocols that has been published in the Journal of Physiology, and there’s an associated commentary from Ele Grandi. In the paper, some … Continue reading

Ablation, scars and insights from parameter lumping
This is quite a long post elaborating on a bit of work I’ve been doing with Greg Morley and his group, which was published in Scientific Reports. I hope it provides an accessible introduction to a fairly complicated set of experiments … Continue reading
Is your model really ‘comprehensive’?
I’ve noticed more and more papers using the phrase “comprehensive model”. This phrase grates every time, and this post is about why. I thought this might just be me getting old and grumpy, so I plotted the mentions of the … Continue reading

Hypotheses on hypotheses on …
(Subtitle: building on foundations of unknown shakiness?) In a lot of fields, a new mathematical model is constructed for each problem, and the model is an encoding of the quantitative rules of the hypothesis you are testing. The model is … Continue reading
