"Cognitive flexibility: Behavioral modeling, interneuron-specific correlates and network-level mechanisms"
Cognitive flexibility refers to the ability to adjust to changing environmental demands and to focus on momentary relevant information. This talk surveys first how working memory and reinforcement learning mediates cognitive flexibility. Then, we show how inhibitory brain cells contribute to these mechanisms and shape how different brain areas communicate during successful behavioral adaptation. This talk identifies the brain cell- and the network-level mechanisms underlying cognitive flexibility.
The presentation will address a fundamental open question about the neural mechanisms underlying cognitive flexibility by proposing a comprehensive research approach that studies the computational level (though behavioral modeling), the implementational level (by describing cell specific mechanisms underlying successful flexible behavior) and representational level (by describing how brain network activity indexes cognitive variables). The objective is to show that such a multi-level investigation is needed to answer the fundamental open questions.
