Serotonergic modulation of learning and plasticity

We are currently studying how serotonin influence learning, and through which neural mechanisms. We are interested in understanding the involvement of specific serotonergic pathways in learning, reward and punishment and neuroplasticity (synaptic and intrinsic plasticity). To this end, we use a combination of behavioural tests (fear conditioning and appetitive conditioning), pharmacology, optical tools and slice electrophysiology)
