Topic: learning strategies

How do animals adapt in a dynamic world? Sometimes, our expectations about the world are drastically violated, such as when we accidentally bite into spoiled food. In these circumstances, we must adjust or face further harm. A classical experimental paradigm to study this behavior is reversal learning, where the values of stimuli are suddenly reversed, for example from positive to negative. Here we investigate how computational models of neural circuits can express the many behavioral strategies empirically observed in reversal learning. We report that simply introducing more neurons in a neu

Metabolic cost for the nervous system is very high due to the complexity of neuronal morphology and the processes to sustain neuronal transmission and synaptic plasticity. Cognitive functions underlying complex behaviors further increase brain energy demands. Despite the interest given to brain metabolism during the last years, how modification of metabolism might contribute to cognitive dysfunctions in brain disorders is not clear. Thus, we aim to identify the key metabolic pathways activated during complex cognitive functions. In this study, we will focus on metabolic pathways activated by d
