I have always been catched by the concept of “neural plasticity”, i.e., the capability of the brain to adapt its structure and function to adjust its output to variations in the input, either in physiological conditions (e.g., learning and memory), or in pathology (e.g., a brain lesion). Indeed, understanding the basic physiology regulating neural plasticity, and how external factors and molecules can modify it, is a fundamental question in neurobiology.
In this regard, my current scientific interests are
i. establishing a map of plasticity at the single-synapse level in response to behavioral stimuli that trigger learning and memory;
ii. defining the molecular fingerprint of synapses actively undergoing plasticity processes
iii. finding strategies to manipulate synaptic plasticity in a non-invasive manner
I am tackling these problems using a combination of electrophysiology, imaging and biochemistry, with the hope of translating the findings to pathological contexts in which synaptic plasticity and neural circuit function are altered, such as Alzheimer’s disease and autism spectrum disorders.
