Theoretical studies suggest that the medial entorhinal cortex might perform some of the essential underlying computations by means of a unique, periodic synaptic matrix that could be self-organized in early development through a simple, symmetry-breaking operation.

Recording neuron ensembles in the rat medial prefrontal cortex to study memory trace reactivation during SWS following learning and execution of cross-modal strategy shifts found that learning influenced which patterns were most strongly encoded and successively reactivated in the hippocampal/prefrontal network.

The results demonstrate that during sleep spindles, the cortex is functionnaly “deafferented” from its hippocampal inputs, based on processes of cortical origin, and presumably mediated by the strong recruitment of inhibitory interneurons.
Hippocampal sharp wave bursts coincide with neocortical "up-state" transitions.
Low-density neuronal ensemble recordings in rats reveal the interaction between synchronized activity in the hippocampus and neocortex, which highlights the interplay in the hippocampal/neocortical loop and may reflect joint memory trace reactivation inthe hippocampus and in the neocortex.

It is shown here, with data from three experiments, that multimodal, local sensory cues can change the directional properties of CA1 pyramidal cells, inducing bidirectionality in a significant proportion of place cells, hence decreasing the orthogonality of hippocampal output.
Oscillations in the prefrontal cortex: a gateway to memory and attention
Light sleep versus slow wave sleep in memory consolidation: a question of global versus local processes?
Attractor neural networks storing multiple space representations: A model for hippocampal place fields
A recurrent neural network model storing multiple spatial maps, or ``charts'', is analyzed, and results suggest a quantitative parallel between theories of hippocampal function in different animal species, such as primates and rodents.
Neural responses to facial expression and face identity in the monkey amygdala.

Neurons were selective for a particular facial expression by either increasing or decreasing their firing rate compared with the firing rates elicited by the other expressions, suggesting global activation in the amygdala might be larger to threatening faces than to neutral or appeasing faces.
