Functional decoupling of BOLD and gamma‐band amplitudes in human primary visual cortex
- Biology, PsychologyHuman brain mapping

It is demonstrated that increased amplitude of gamma‐band oscillations as measured with MEG is not sufficient to drive the subsequent BOLD response, and functional decoupling is demonstrated.

The relationship between blood oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI) and magnetoencephalography (MEG) metrics were explored using low-level visual stimuli known to elicit a rich variety of neural responses, providing further evidence that the relationship between the fMRI-BOLD response and cortical neural activity is complex.

Spatiotemporal Frequency and Direction Sensitivities of Human Visual Areas Measured Using fMRI
- Biology, PsychologyNeuroImage
- 2000
Visual areas V1, V2, V3, and V3A showed more direction sensitivity at low spatial frequencies, while VP, V4, andV5 had the highest drifting versus counterphasing ratios for higher spatial frequencies.

The resemblance between the BOLD response to the stimulus presentation frequency and the base‐line power spectra at the same frequencies suggests that the same underlying mechanism could be responsible for both curves and that the base-line fMRl power spectrum is probably due to base‐ line electrical activity in the brain.

This study demonstrates how SAM, spatial normalization, and intersubject averaging enable group MEG studies to be performed and represents an important advance in the use of MEG as a cognitive neuroimaging technique and also allows mutual cross-validation with fMRI.

The responses of simple cells were measured as a function of the contrast and the frequency of sine-wave grating patterns in order to explore the effect of contrast on the spatial and temporal phase transfer functions and on the spatiotemporal receptive field.

It is concluded that areas 17 and 18 act in parallel to process different aspects of the visual information relayed from the retina via the lateral geniculate complex.

The results indicate highly correlated changes in the strength of the EEG signal averaged over two occipital electrodes and the BOLD signal within the occipitals lobe as a function of flash frequency for 7/8 subjects (average linear correlation coefficient of 0.76).
