Sotiris Masmanidis

The Masmanidis is interested in understanding the neural basis of simple reward-guided behaviors such as Pavlovian conditioning. They primarily study neural dynamics of corticostriatal circuits, and try to understand how these dynamics are regulated by external inputs and local microcircuits, and their behavioral function. Their approach relies on using silicon microprobe electrode arrays to record the activity of large populations of neurons. They combine large-scale recordings with optogenetic perturbations to determine the contribution of specific circuits on neural dynamics and information processing, and to establish causal links between neural activity and behavior.
