Abstract
Interneurons are the main controller of the excitatory/inhibitory balance, sensory tuning and plasticity. Yet, it is unclear how their activity is regulated at the molecular level to shape complex network functions and behaviour. During my talk, I will present a mechanism essential to the temporal processing capabilities of the cortical and striatal networks. I will show that the ETV1/Er81 transcription factor is required for normal circuit activity and time-locked responses to sensorimotor inputs in awake mice. I will demonstrate that ETV1/Er81 fine-tunes interneuron activity and that specific ablation of the transcription factor in cortical and striatal interneurons leads to prominent changes in their molecular, morphological, and electrophysiological features. Finally, I will discuss how this cell type-specific molecular control of interneuron activity drives mouse behaviour in health and disease.
