Neural bases of the non-conscious perception of emotional signals
Department of Psychology, University of Torino
Cognitive and Affective Neuroscience Lab, Tilburg University
Only a fraction of sensory input gives rise to conscious perception. A visual stimulus may go undetected because it is filtered out by attentional selection (attentional unawareness) or because its sensory processing is insufficient to generate a conscious perception even when we are paying attention to it (sensory unawareness). Compelling evidence shows emotional stimuli may be processed without being consciously perceived, thereby inducing congruent behavioral and neurophysiological responses in the unaware observer.
In the present talk I will discuss some original studies investigating the psychophysiological responses associated to non-conscious emotion perception, the neurofunctional systems sustaining such processing, and the underlying brain networks and anatomical connections.
The commonalities and differences between sensory and attentional unawareness for emotions are described, with a specific focus on neuro-pathological conditions that selectively induce sensory or attentional unawareness, such as cortical blindness and "blindsight" or hemispatial neglect, respectively.

I nostri giovani ricercatori aggiornano i colleghi sulle loro ricerche. Appuntamento ogni due venerdì.
Il nostro gruppo di ricerca guidato da Luca Bonfanti ha individuato una riserva di neuroni “immaturi” in zone inedite del cervello: si aprono nuovi scenari per compensare la scarsa capacità del cervello di rigenerarsi. Lo studio è stato pubblicato sul Journal of Neuroscience di dicembre.
