Selective averaging of rapidly presented individual trials using fMRI

A major limitation in conducting functional neuroimaging studies, particularly for cognitive experiments, has been the use of blocked task paradigms. Here we explored whether selective averaging techniques similar to those applied in event‐related potential (ERP) experiments could be used to demonstrate functional magnetic resonance imaging (fMRI) responses to rapidly intermixed trials. In the first two experiments, we observed that for 1‐sec trials of full‐field visual checkerboard stimulation… 

Quantifying learning-dependent changes in the brain: Single-trial multivoxel pattern analysis requires slow event-related fMRI.

A trial-by-trial similarity analysis of fMRI and pupil dilation responses during discriminant aversive conditioning revealed clear single-trial learning curves in conditions with intermediate and long intervals, indicating that rapid event-related designs are not suited for single- Trial pattern analysis.

Event‐related fMRI: Comparison of conditions with varying BOLD overlap

The data support the view that BOLD overlap leads to largely linear signal changes and task‐related increases in the BOLD response were detected equally well with substantial BOLD overlaps as with mostly nonoverlapping BOLD responses.

Detection power, temporal response, and spatial resolution of IRON fMRI in awake, behaving monkeys at 3 Tesla

Preliminary data suggests multi-shot EPI with navigators may be useful in improving image stability at higher resolution for IRON fMRI, which can employ short echo times to minimize phase variations, while achieving maximum efficiency by increasing the MION dose.

Paradigm‐dependent modulation of event‐related fMRI activity evoked by the oddball task

Although ER‐fMRI is relatively insensitive as a technique to small variations in the timing of stimulus‐evoked responses, it is remarkably sensitive to consequences such variations have for the topographic location and amplitude of neural responses to stimuli.

Modulation of task-related neural activity in task-switching: an fMRI study.

BOLD Correlates of Trial-by-Trial Reaction Time Variability in Gray and White Matter: A Multi-Study fMRI Analysis

The results highlight the importance of modeling trial-by-trial RT in fMRI analyses and raise the possibility that RT variability may provide a powerful probe for investigating the previously elusive white matter BOLD signal.

Delayed effects of attention in visual cortex as measured with fMRI




Detection of cortical activation during averaged single trials of a cognitive task using functional magnetic resonance imaging.

These findings suggest that single-trial paradigms will be able to exploit the high temporal resolution of fMRI and provide experimental flexibility and time-resolved data for individual brain regions on a trial-by-trial basis.

Linear Systems Analysis of Functional Magnetic Resonance Imaging in Human V1

Results from three empirical tests support the hypothesis that fMRI responses in human primary visual cortex (V1) depend separably on stimulus timing and stimulus contrast, and the noise in the fMRI data is independent of stimulus contrast and temporal period.

Empirical Analyses of BOLD fMRI Statistics

An implementation of a general linear model for autocorrelated observations in which the voxel-wise false-positive rates in fMRI "noise" datasets were stabilized and brought close to theoretical values is described.

Late Onset of Anterior Prefrontal Activity during True and False Recognition: An Event-Related fMRI Study

Event-related analyses of time course data show a relatively late onset and sustained duration for anterior prefrontal signal changes compared to signal changes in other activated regions, consistent with the idea that anterior prefrontal regions participate in postretrieval monitoring processes.

Distortion of ERP averages due to overlap from temporally adjacent ERPs: analysis and correction.

A set of algorithms is presented for estimating and removing the residual distortion due to response overlap from recorded ERP averages, collectively termed the Adjacent Response (Adjar) Technique, which can alleviate many of the overlap-related problems that arise when short ISIs are used, thereby enhancing the power of the ERP technique.

Differential activation of the prefrontal cortex in successful and unsuccessful memory retrieval.

It is concluded that the prefrontal cortex, especially in the right hemisphere, is more active when a retrieval attempt succeeds than when it fails, consistent with the idea that the cortex supports processes that operate selectively on the products of memory retrieval.

The attempt to understand the neural underpinnings of cognition began in earnest, almost a century and a half ago, with the discovery that the left cerebral hemisphere of humans was related to

Lateralized human brain language systems demonstrated by task subtraction functional magnetic resonance imaging.

The results demonstrate the lateralized anatomy of semantic linguistic systems in contrast to non-linguistic auditory sensory processors and introduce a task subtraction technique adapted for functional MRI as a noninvasive measure of language lateralization.

Transient brain activity used in magnetic resonance imaging to detect functional areas

The results suggest that the delineation of transient ROIs, by targeting a period ∼7 s after transient neural activity, can be useful for fMRI studies of cognitive functions.
