It is proposed that the CS evokes EPSPs at sensory input synapses onto LA pyramidal neurons, and that the US strongly depolarizes these same LA neurons, which induce LTP-like changes that store memories during fear conditioning.

Computer simulations and mathematical analysis demonstrated how a postsynaptic neuron can detect location-dependent synchrony among inputs from such theta cells, and thereby mimic the spatial tuning properties of place, grid, or border cells.
Conversion of a phase‐ to a rate‐coded position signal by a three‐stage model of theta cells, grid cells, and place cells
A three‐stage network model is described, which formalizes the computational steps that are necessary for converting phase‐coded position signals (represented by theta oscillations) into rate‐coded positions signals ( represented by grid cells and place cells).
Memory consolidation of Pavlovian fear conditioning: a cellular and molecular perspective
Scale-Invariant Memory Representations Emerge from Moiré Interference between Grid Fields That Produce Theta Oscillations: A Computational Model
It is shown that grid fields can combine with one another to form moiré interference patterns, referred to as “moiré grids,” that replicate the hexagonal lattice over an infinite range of spatial scales.
Anticipatory time intervals of head-direction cells in the anterior thalamus of the rat: implications for path integration in the head-direction circuit.
A neural circuit mechanism is proposed to account for the firing behavior observed in the anterior thalamus of freely moving rats, and how this circuit might serve as a functional component of a neural system for path integration of the rat's directional heading is discussed.

Investigation of neural pathways that relay information about the UCS to the amygdala by recording neurons in the amygdala and periaqueductal gray of rats during fear conditioning found UCS-evoked responses in both amygdala and PAG were inhibited by expectation.
