Beyond the peak–Tactile temporal discrimination does not correlate with individual peak frequencies in somatosensory cortex

TJ Baumgarten, A Schnitzler, J Lange - Frontiers in Psychology, 2017 - frontiersin.org
The human sensory systems constantly receive input from different stimuli. Whether these
stimuli are integrated into a coherent percept or segregated and perceived as separate …

10 Hz tACS over somatosensory cortex does not modulate supra-threshold tactile temporal discrimination in humans

MA Wittenberg, M Morr, A Schnitzler… - Frontiers in …, 2019 - frontiersin.org
Perception of physical identical stimuli can differ over time depending on the brain state.
One marker of this brain state can be neuronal oscillations in the alpha band (8–12 Hz). A …

Individual alpha frequency predicts perceived visuotactile simultaneity

D Migliorati, F Zappasodi, MG Perrucci… - Journal of cognitive …, 2020 - direct.mit.edu
Temporal encoding is a key feature in multisensory processing that leads to the integration
versus segregation of perceived events over time. Whether or not two events presented at …

Somatosensory temporal discrimination threshold involves inhibitory mechanisms in the primary somatosensory area

L Rocchi, E Casula, P Tocco, A Berardelli… - Journal of …, 2016 - Soc Neuroscience
Somatosensory temporal discrimination threshold (STDT) is defined as the shortest time
interval necessary for a pair of tactile stimuli to be perceived as separate. Although STDT is …

Alpha oscillations and temporal binding windows in perception—A critical review and best practice guidelines

JM Schoffelen, UG Pesci, U Noppeney - Journal of Cognitive …, 2024 - direct.mit.edu
An intriguing question in cognitive neuroscience is whether alpha oscillations shape how
the brain transforms the continuous sensory inputs into distinct percepts. According to the …

The phase of prestimulus alpha oscillations affects tactile perception

L Ai, T Ro - Journal of neurophysiology, 2014 - journals.physiology.org
Previous studies have shown that neural oscillations in the 8-to 12-Hz range influence
sensory perception. In the current study, we examined whether both the power and phase of …

Percept of the duration of a vibrotactile stimulus is altered by changing its amplitude

EM Francisco, JK Holden, RH Nguyen… - Frontiers in Systems …, 2015 - frontiersin.org
There have been numerous studies conducted on time perception. However, very few of
these have involved tactile stimuli to assess a subject's capacity for duration discrimination …

Sensory drive modifies brain dynamics and the temporal integration window

G Karvat, N Ofir, AN Landau - Journal of Cognitive Neuroscience, 2024 - direct.mit.edu
Perception is suggested to occur in discrete temporal windows, clocked by cycles of neural
oscillations. An important testable prediction of this theory is that individuals' peak …

Resting BOLD fluctuations in the primary somatosensory cortex correlate with tactile acuity

LM Haag, S Heba, M Lenz, B Glaubitz, O Höffken… - Cortex, 2015 - Elsevier
Sensory perception, including 2-point discrimination (2ptD), is tightly linked to cortical
processing of tactile stimuli in primary somatosensory cortices. While the role of cortical …

Neural timing signal for precise tactile timing judgments

S Kuroki, J Watanabe… - Journal of …, 2016 - journals.physiology.org
The brain can precisely encode the temporal relationship between tactile inputs. While
behavioural studies have demonstrated precise interfinger temporal judgments, the …
