How to infer grid-cell-like coding from right entorhinal fMRI: estimate a hidden grid orientation, test hexadirectional modulation out-of-sample, and rule out confounds.

A voxel-level fMRI demo: generate synthetic Right EC BOLD, decode population phi with train/test GLM, and compare recovered orientation against ground truth.

Experimental work shows that grid fields are not rigidly universal: trapezoids and other environmental deformations can stretch, rotate, and locally warp the grid pattern.

A theory-only demo showing the firing map generated by three-wave interference and the corresponding spatial autocorrelogram.

Extend the oscillatory-interference picture to multiple waves by fixing the movement direction and projecting velocity onto each preferred direction through cos(theta_i).

A first note on oscillatory interference when motion is aligned with a wave's preferred direction, and why the resulting firing spacing becomes a cell-specific constant.

A first dynamic demo: steer a rat through a 2x2 arena, watch phase-driven waves evolve, and accumulate a fading grid-cell firing map.
