Local Inhibitory Dynamics Underpin Temporal Integration and Functional Segregation between Barrels and Septa in the Mouse Barrel Cortex

Ali Özgür Argunşah, Tevye Jason Stachniak, Jenq‐Wei Yang, Linbi Cai, Alexander van der Bourg, Rahel Kästli, Theofanis Karayannis

The paper identifies local inhibitory dynamics in mouse barrel cortex that support temporal integration and functional segregation between barrels and septa during whisker stimulation.

Adolescent Astrocyte Dysregulation Impairs Prefrontal Interneuron Maturation and Adult Cognition

Johanna Furrer, Viktor Beilmann, Anna Cavaccini, Eliane Boesch, Sina M. Schalbetter, Ali Özgür Argunşah, Sarai Fischer, Aurelia Portmann, Olga Krzyzaniak, Felipe Velasquez Moros, Luca Ravotto, Theofanis Karayannis, Bruno Weber, Tina Notter

This study shows that abnormal astrocyte activity during adolescent prefrontal cortex development leads to synaptic loss, interneuron dysfunction, and cognitive deficits.

Learning reorganizes dendritic and stabilizes axonal initial segment inhibitory synapses in CA1 pyramidal neurons

H. Klimmt, David Kappel, A.F. Ulivi, Ali Özgür Argunşah, Bhargavi Murthy, S. Somatakis, Rosa-Eva Huettl, Stefan Remy, Alessio Attardo

The paper tracks inhibitory synapses in CA1 pyramidal neurons over time and shows learning induces reorganization of dendritic synapses and stabilization of axonal initial segment synapses.

The Temporal Pattern of Synaptic Activation Determines the Longevity of Structural Plasticity at Single Dendritic Spines

Ali Özgür Argunşah, Inbal Israely

The study investigates how naturalistic synaptic activity patterns affect structural plasticity in hippocampal dendritic spines, finding that temporal structure and NMDAR activity determine plasticity longevity.

Post-mitotic Prox1 expression controls the final specification of cortical VIP interneuron subtypes

Tevye Jason Stachniak, Rahel Kästli, Olivia Hanley, Ali Özgür Argunşah, Elianne Grietje Theodora van der Valk, George Kanatouris, Theofanis Karayannis

This study shows that Prox1 regulates the final specification of VIP interneuron subtypes by controlling Elfn1 function in post-mitotic stages.

Developmental Divergence of Sensory Stimulus Representation in Cortical Interneurons

Rahel Kästli, Rasmus Vighagen, Alexander van der Bourg, Ali Özgür Argunşah, Asim Iqbal, Fabian F. Voigt, Daniel S. Kirschenbaum, Adriano Aguzzi, Fritjof Helmchen, Theofanis Karayannis

The paper identifies a developmental transition in VIP+ and SST+ interneurons in the mouse barrel cortex around P14, where their responses to multi-whisker stimuli diverge and their thalamic inputs shift.
