Months-long stability of the head-direction system

Sofía Skromne Carrasco, Guillaume D Viejo, Adrien Peyrache

The paper shows that the head-direction system in mice maintains stable neuronal code and environment-specific mappings over several months.

Nature · Feb 11, 2026Peer-reviewedNeuroscience

The head-direction signal is generated by multiple attractor-like networks

Guillaume D Viejo, Sofía Skromne Carrasco, Adrien Peyrache

This study shows that thalamic coherence in HD neurons can emerge from local processes rather than relying on LMN input during non-REM sleep.

Precise coupling of the thalamic head-direction system to hippocampal ripples.

Guillaume D Viejo, Adrien Peyrache

The paper shows that head-direction cells in the anterior thalamus are stably aligned before hippocampal ripples, while other thalamic cells show diverse, cell-specific coupling to the hippocampus.

Brain-state invariant thalamo-cortical coordination revealed by non-linear encoders

Guillaume D Viejo, Thomas Cortier, Adrien Peyrache

The paper uses gradient boosted trees to analyze neuronal data and reveals brain-state invariant coordination in thalamo-cortical circuits during wakefulness and sleep.
