Konstantina Kilteni presents Why you cannot tickle yourself: action prediction influences on somatosensory perception
On 2024-11-21 11:00:00 at G205, Karlovo náměstí 13, Praha 2
Please come to the seminar by Konstantina Kilteni, currently PI of her ERC
Grant
"Ticklish Human".
Self-generated touch feels less intense and less ticklish than the same touch
applied externally. Motor control theories suggest that cerebellar internal
models predict somatosensory reafference, attenuating or even canceling the
perception of the actual touch. Despite this influential theoretical framework,
little is known about the details of this predictive attenuation phenomenon. I
will present a series of findings from psychophysical and neuroimaging
experiments suggesting that somatosensory attenuation is a byproduct of the
brain's predictions and depends on a learned internal model linking specific
actions to their somatosensory outcomes.
