Blind individuals’ enhanced ability to sense their own heartbeat is related to the thickness of their occipital cortex
Stroh, A-L; Radziun, D; Korczyk, M; Crucianelli, L; Ehrsson, HH; Szwed, M (bioRxiv, 2024-02-28)Blindness is associated with heightened sensory abilities, such as improved hearing and tactile acuity. Moreover, recent evidence suggests that blind individuals are better than sighted individuals at perceiving their own ... -
Interoception as independent cardiac, thermosensory, nociceptive, and affective touch perceptual submodalities.
Crucianelli, L; Enmalm, A; Ehrsson, HH (2022-07)Interoception includes signals from inner organs and thin afferents in the skin, providing information about the body's physiological state. However, the functional relationships between interoceptive submodalities are ... -
Limits of cross-modal plasticity? Short-term visual deprivation does not enhance cardiac interoception, thermosensation, or tactile spatial acuity.
Radziun, D; Crucianelli, L; Ehrsson, HH (2022-02)In the present study, we investigated the effect of short-term visual deprivation on discriminative touch, cardiac interoception, and thermosensation by asking 64 healthy volunteers to perform four behavioral tasks. The ... -
Modeling affective touch pleasantness across skin types at the individual level reveals a reliable and stable basic function.
Crucianelli, L; Chancel, M; Ehrsson, HH (2022-12-01)Touch is perceived most pleasant when delivered at velocities known to optimally activate the C-tactile afferent system. At the group level, pleasantness ratings of touch delivered at velocities in the range between 0.3 ... -
The perception of affective and discriminative touch in blind individuals
Radziun, D; Crucianelli, L; Korczyk, M; Szwed, M; Ehrsson, HH (Elsevier, 2023-02-24)Enhanced tactile acuity in blindness is among the most widely reported results of neuroplasticity following prolonged visual deprivation. However, tactile submodalities other than discriminative touch are profoundly ... -
The Role of the Skin in Interoception: A Neglected Organ?
Crucianelli, L; Ehrsson, HH (2023-01)In the past 2 decades, interoception has received increasing attention in the fields of psychology and cognitive science, as well as neuroscience and physiology. A plethora of studies adopted the perception of cardiac ... -
Subcortical contributions to the sense of body ownership
Crucianelli, L; Reader, AT; Ehrsson, HH (Oxford University Press, 2023-10-17)The sense of body ownership (i.e., the feeling that our body or its parts belong to us) plays a key role in bodily self-consciousness and is believed to stem from multisensory integration. The development of experimental ... -
Thermosensation and emotion: Thermosensory accuracy in a dynamic thermal matching task is linked to depression and anxiety symptomatology.
Crucianelli, L; Radziun, D; Ehrsson, HH (2023-11-14)Interoception is related to the generation of bodily feelings and the awareness of ourselves as 'sentient beings', informing the organism about its bodily needs to guarantee survival. Previous studies have reported links ... -
Visuo-thermal congruency modulates the sense of body ownership.
Crucianelli, L; Ehrsson, HH (2022-07-22)Thermosensation has been redefined as an interoceptive modality that provides information about the homeostatic state of the body. However, the contribution of thermosensory signals to the sense of body ownership remains ...
