Ongoing neuronal population activity dynamics in the neocortex - representational drift in experiment and model

Published in Johann Wolfgang Goethe-Universität Frankfurt am Main, 2022

PhD thesis on representational drift in neocortical populations, investigating mechanisms through both experimental data and computational modeling.

Learning-induced biases in the ongoing dynamics of sensory representations predict stimulus generalization

Published in Cell Reports, 2022

We show that learning-induced plasticity in representations of sound stimuli in mouse auditory cortex weaves into ongoing representational drift.

A stable sensory map emerges from a dynamic equilibrium of neurons with unstable tuning properties

Published in Cerebral Cortex, 2023

Despite stability in topographic maps, individual neurons undergo substantial reformatting. We show sensory maps are maintained by drifting subpopulations of neurons.

Statistical learning and representational drift: A dynamic substrate for memories

Published in Current Opinion in Neurobiology, 2025

We propose that statistical learning maintains stable representational similarities despite continuous neuronal drift, providing a dynamic substrate for memory formation and stability.

Homeostasis of a representational map in the neocortex

Published in Nature Neuroscience, 2025

We show how homeostatic mechanisms in auditory cortex protect representational maps after neuron loss, with recovery driven by plasticity in initially unresponsive neurons.

Representational drift reflects ongoing balancing of stochastic changes by Hebbian learning

Published in Proceedings of the National Academy of Sciences, 2026

We show that representational drift results from an interplay between Hebbian plasticity and stochastic synaptic changes.

Towards Circuit Mechanisms of the Creative Process

Published in Creativity Research Journal, 2026

Published in bioRxiv, 2026

We show that random connectivity in neural networks preserves representational similarity despite ongoing activity drift.
