Subliminal modulation of voluntary action experience: A neuropsychological investigation
Human voluntary actions are often associated with a distinctive subjective experience termed 'sense of agency'. This experience could be a reconstructive inference triggered by monitoring one's actions and their outcomes, or a read-out of brain processes related to action preparation, or some hybrid of these. Participants pressed a key with the right index finger at a time of their own choice, ...
متن کاملHigh-resolution BOLD fMRI measurements of local orientation-dependent contextual modulation show a mismatch between predicted V1 output and local BOLD response
The blood oxygenation level-dependent (BOLD) functional MRI response to suppressive neural activity has not been tested on a fine spatial scale. Using Gabor patches placed in the near periphery, we precisely localized individual regions of interest in primary visual cortex and measured the response at a range of contrasts in two different contexts: with parallel and with orthogonal flanking Gab...
متن کاملCharacterization of the BOLD Hemodynamic Response Function at 7T: towards separation of vasculature and parenchyma
Introduction A limitation of T2weighted BOLD fMRI is the confounding contribution of signal from the larger vasculature. An improved BOLD specificity to parenchyma can be achieved at high field strengths such as 7T due to increased contrast-to-noise ratio, and reduced contribution of intravascular signal as compared to lower field strengths. Moreover, at 7T high spatial and temporal resolution ...
متن کاملReal-time automated spectral assessment of the BOLD response for neurofeedback at 3 and 7T.
Echo-planar imaging is the dominant functional MRI data acquisition scheme for evaluating the BOLD signal. To date, it remains the only approach providing neurofeedback from spatially localized brain activity. Real-time functional single-voxel proton spectroscopy (fSVPS) may be an alternative for spatially specific BOLD neurofeedback at 7T because it allows for a precise estimation of the local...
متن کاملInitial experience with BOLD imaging of the kidneys at 7T
MOTIVATION Functional renal imaging is an area of growing interest [1]. BOLD imaging of the kidneys is one of the functional techniques explored. This technique has the potential to study changes in blood flow and oxygenation in the hypoxic renal medulla. Depending on the amount of hypoxia in the medulla, the BOLD contrast between renal cortex and medulla changes. This change in contrast can be...
