An expert system to simulate fuzzy phenomena in cardiac electrophysiology

Mathematical and Computer Modelling, 1988
To simulate fuzzy phenomena in clinical cardiac electrophysiology an expert system has been combined with a classical mathematical model of the cardiac conduction system. Rules describing the fuzzy phenomenon that should be simulated should be stored in the knowledge base of the expert system.

Mixed-mode oscillations in pyramidal neurons under antiepileptic drug conditions. [PDF]

PLoS ONE, 2017
Subthreshold oscillations in combination with large-amplitude oscillations generate mixed-mode oscillations (MMOs), which mediate various spatial and temporal cognition and memory processes and behavioral motor tasks.
