Computed membrane action potentials for shocks of 5.5, 6.0, 6.45, 6.6 and 7.5 mV. The three weakest decay back towards rest; the two strongest produce full spikes of about 105 mV.

Three stacked line charts. Top: an action potential rising to about 105 mV, decaying, and undershooting before it returns to rest. Middle: sodium conductance peaking near 33 and falling away while potassium conductance rises more slowly and decays later. Bottom: the m, h and n gating variables crossing over during the impulse.

A 1952 model, fitted to one kind of experiment, predicted four things that it had never been shown. This is effectively the case for mechanistic modelling.

The M.Res. is finished, a poster got picked apart in the most useful way, and the next thing is going to need more maths.

A short overview of LLMs I gave at lab meeting — what they are, how they got here, and where they’re useful or dangerous in a research workflow.

First lab-meeting walkthrough of the calibrated platelet Ca²⁺ model — good questions, some surprising offers of follow-up work.
