N. Pitsikas is Associate Professor of Pharmacology in the Medical School of the University of Thessaly at Larissa. His research interests are focused in the field of Behavioural Pharmacology. In particular, he investigates the role of nitric oxide, of 5-HT2c and 5-HT6 receptors in cognition, anxiety and schizophrenia. He also studies the psychotomimetic effects of different N-methyl-D-aspartate (NMDA) receptor antagonists and the role exerted by agonists and antagonists of the metabotropic mGlu2/3 receptor in cognition, anxiety, schizophrenia and obsessive compulsive disorder. Finally, he studies the role exerted by the plant Crocus Sativus and its extracts in the treatment of different pathologies of the central nervous system
He is involved in a vast number of research programs either as scientific responsible or as a team member. He has different scientific collaborations both in Greece (University of Ioannina, Agricultural University of Athens, Biomedical Research Foundation, Academy of Athens) and with foreign scientific research centers in Italy and in USA.
