Grid cells and cortical representation
… Lines in left and middle panels indicate two axes of the grid pattern (which define grid
orientation); crosses in the panel on the right indicate grid phase (x–y location of grid fields). c | …

Path integral methods for the dynamics of stochastic and disordered systems
We review some of the techniques used to study the dynamics of disordered systems
subject to both quenched and fast (thermal) noise. Starting from the Martin–Siggia–Rose/Janssen–…

Ising model for neural data: model quality and approximate methods for extracting functional connectivity
Y Roudi, J Tyrcha, J Hertz - Physical Review E, 2009 - APS
We study pairwise Ising models for describing the statistics of multineuron spike trains,
