Perceptual awareness of near-threshold tones scales gradually with auditory cortex activity and pupil dilation [Research Data]
Jul 3, 2024
Doll, Laura; Dykstra, Andrew; Gutschalk, Alexander, 2024, "Perceptual awareness of near-threshold tones scales gradually with auditory cortex activity and pupil dilation [Research Data]", https://doi.org/10.11588/data/CCOAS7, heiDATA, V1
Abstract: Negative-going responses in sensory cortex co-vary with perceptual awareness of sensory stimuli. Given that this awareness negativity has also been observed for undetected stimuli, some have challenged its role for perception. To address this question, we combined magne...
A role for retro-splenial cortex in the task-related P3 network [Research Data]
Dec 13, 2023
Das, Diptyajit; Shaw, Marnie E.; Hämäläinen, Matti S.; Dykstra, Andrew R.; Doll, Laura; Gutschalk, Alexander, 2023, "A role for retro-splenial cortex in the task-related P3 network [Research Data]", https://doi.org/10.11588/data/YB9SQI, heiDATA, V1
Objective: The P3 is an event-related response observed in relation to task-relevant sensory events. Despite its ubiquitous presence, the neural generators of the P3 are controversial and not well identified. Methods: We compared source analysis of combined magneto- and electroen...
Auditory cortex activity related to perceptual awareness versus masking of tone sequences [research data]
Jan 5, 2021
Gärtner, Kai; Gutschalk, Alexander, 2021, "Auditory cortex activity related to perceptual awareness versus masking of tone sequences [research data]", https://doi.org/10.11588/data/Y8UEOY, heiDATA, V1
ABSTRACT: Sequences of repeating tones can be masked by other tones of different frequency. When these tone sequences are perceived, nevertheless, a prominent neural response in the auditory cortex is evoked by each tone of the sequence. When the targets are detected based on the...
