Constructive memory & generalization: New preprint

Our new preprint on constructive memory for temporal relations and generalization is now on bioRxiv.

Poster at virtual CNS 2021

The 2021 annual meeting of the Cognitive Neuroscience Society will take place online and I am excited to present a poster there.

Deforming the metric of cognitive maps distorts memory

Environmental boundaries anchor cognitive maps that support memory. However, trapezoidal boundary geometry distorts the regular firing patterns of entorhinal grid cells, proposedly providing a metric for cognitive maps. Here we test the impact of …

The hippocampus constructs interval-scale sequence memories and generalizes temporal structure across sequences

The hippocampus constructs sequence memories that generalize temporal relations across sequences

Interval-scale sequence memories in the hippocampus generalize temporal structure across sequences

Cognitive maps for spatial and temporal memory

The hippocampal-entorhinal region forms cognitive maps of space and stimulus relations in general. In this talk, I will address how cognitive maps underlie human spatial and temporal memory. First, I will show that boundary geometry distorts spatial …

Piecing together cognitive maps one dimension at a time

In this issue of Neuron, Park et al. (2020) show that the brain forms unified cognitive maps of relational knowledge. The hippocampal-entorhinal region and medial prefrontal cortices spontaneously combine multiple, distinct rank orders to …

The spontaneous formation of two-dimensional cognitive maps: Preview in Neuron

I had the pleasure of writing a Preview for Neuron for a recent paper by Erie Boorman’s group. It’s out now!
