Offline hippocampal reactivation during dentate spikes supports flexible memory

Stephen B. McHugh, Vítor Lopes‐dos‐Santos, Manfredi Castelli, Giuseppe P. Gava, Sophie E. Thompson, Shu K. E. Tam, Katja Hartwich, Brook A. L. Perry, Robert A. Toth, Timothy Denison, Andrew Sharott, David Dupret

This study shows that dentate spikes (DSs) during sleep reactivate memory-related neuronal patterns, supporting flexible memory, and are distinct from sharp-wave ripples (SWRs) in their structure and function.

Organizing the coactivity structure of the hippocampus from robust to flexible memory

Giuseppe P. Gava, Laura Lefèvre, Tabitha Broadbelt, Stephen B. McHugh, Vítor Lopes‐dos‐Santos, Demi Brizee, Katja Hartwich, Hanna T. Sjoberg, Pavel V. Perestenko, Robert Toth, Andrew Sharott, David Dupret

The paper shows that forming a robust memory restricts hippocampal coactivity, impairing flexible memory formation, and that optogenetic suppression during robust memory formation restores flexibility.

Spread of pathological human Tau from neurons to oligodendrocytes and loss of high-firing pyramidal neurons in ageing mice

Tim J. Viney, Barbara Sárkány, A. Tugrul Ozdemir, Katja Hartwich, Judith V. Schweimer, David M. Bannerman, Péter Somogyi

This study investigates how human pTau affects hippocampal neurons and network activity in tauopathy model mice, finding pTau accumulation in pyramidal neurons and spread to oligodendrocytes, with preserved neuronal coordination despite neurodegeneration.
