Anhedonia, a transdiagnostic symptom prevalent in depressive and psychotic disorders, poses a significant challenge for pharmacological intervention due to its association with impaired motivation. Understanding how psychotropic drugs can modulate this pathological domain and elucidating the molecular mechanisms underlying such effects are crucial endeavors in psychiatric research. In this study, we aimed to investigate the pro-motivational properties of lurasidone in a rat (Sprague Dawley males) model of anhedonia and to unravel the interplay between lurasidone and the brain regions critical for reward processing.

December 2024
Department of Psychology, University of Milan-Bicocca.
Interpersonal coordination processes facilitate interpersonal synchrony through a continuous mutual adaption and corepresentation of self and others' actions. Such a process has been found to enhance prosocial behaviors, affiliation, and trust. While research has investigated the general underlying cognitive and social mechanisms that facilitate interpersonal synchrony, much less is known about how interpersonal impairments influence it in various psychopathological conditions-such as borderline personality disorder (BPD).
