An Evaluation of the Accuracy of Classical Models for Computing the Membrane Potential and Extracellular Potential for Neurons
Aslak Tveito,Aslak Tveito,Karoline Horgmo Jæger,Glenn T. Lines,Łukasz Paszkowski,Joakim Sundnes,Joakim Sundnes,Andrew G. Edwards,Andrew G. Edwards,Tuomo Māki-Marttunen,Geir Halnes,Gaute T. Einevoll,Gaute T. Einevoll +12 more
TL;DR: The present work explores the accuracy of the classical models (a) and (b) by comparing them to more accurate models available where the potentials inside and outside the neurons are computed simultaneously in a self-consistent scheme.

Efficient computation of steady states in large-scale ODE models of biochemical reaction networks
Glenn T. Lines,Łukasz Paszkowski,Leonard Schmiester,Daniel Weindl,Paul Stapor,Jan Hasenauer,Jan Hasenauer +6 more
TL;DR: This paper uses Newton’s method - like some previous studies - and develops several improvements to achieve robust convergence and shows that the method works robustly in this setting and achieves a speed up of up to 100 compared to using ODE solves.

Efficient computation of adjoint sensitivities at steady-state in ODE models of biochemical reaction networks
Polina Lakrisenko,Paul Stapor,Stephan Grein,Łukasz Paszkowski,Dilan Pathirana,Fabian Fröhlich,Glenn T. Lines,Daniel Weindl,Jan Hasenauer +8 more
TL;DR: A new gradient computation method is proposed that facilitates the parameterization of large-scale models based on steady-state measurements that can be combined with existing gradient computation methods for time-course measurements.
