Andrea Mele is Associate Professor of Psychobiology at the Department of Biology and Biotechnology of Sapienza University of Rome.
He graduated in Biology at Sapienza in 1987. He worked as a Postdoctoral Fellow at the National Institute of Mental Health, in Bethesda, with Agu Pert and Robert M. Post, focusing on the effects of drug of abuse on the dopaminergic system.
Neural circuits in learning and memory
We are interested in the neural mechanisms underlying memory, at a molecular and neural circuit level. Our approach combines pharmacological, molecular, and behavioral analyses to understand the temporal dynamic of memory stabilization.
Learning and memory are two of the most important capabilities of our mind. They allow the acquisition of new knowledge and the retention and reconstruction of this knowledge over time. Our group has demonstrated that complex associative learning and memory requires the activation not only of medial temporal lobe associated brain structure but also that of different components of the striatal complex (Ferretti et al., 2010). Using a comparative approach we investigated molecular processes underlying memory formation in the hippocampus and in the striatal complex demonstrating striking differences between the two brain regions suggesting that memory consolidation depends on molecular processes with a complex spatiotemporal dynamic (Capitano et al., 2016a; Capitano et al., 2016b). We are currently working on the functional relationship between the hippocampus and the striatum in learning and memory and how these circuits support different form of learning.
We aim to discover the neural circuits and molecular mechanisms that support learning and memory in health and disease. In the long term our findings could help the refinement of theoretical models, and may be insightful for developing new theories on the biological mechanisms underlying learning and memory as well as for the development of new therapeutic strategies for mental illness.
