Bold Aspirations

MEG versus BOLD MR imaging: functional imaging, the next generation?

Blood oxygen level–dependent functional MR (BOLD fMR) imaging, long accepted as a powerful research technique in the cognitive sciences and neurosciences, recently has gained acceptance as a clinical tool. Clinical applications of BOLD imaging have focused primarily on the preoperative locali-zation of the motor, sensory, and language centers of the brain in anticipation of tumor or vascular ma...

BOLD impulse response functions and baseline-dependent response adaptation

INTRODUCTION It is well known that the BOLD impulse response functions (IRFs) show some degree of variability – primarily represented by either a presence or absence of a delayed undershoot – across different stimuli and/or regions. However a mechanistic basis of the BOLD-IRF variability is unknown. We hypothesized that BOLD-IRFs could be different due to the system’s variable adaptive properti...

Interpreting the BOLD signal.

The development of functional magnetic resonance imaging (fMRI) has brought together a broad community of scientists interested in measuring the neural basis of the human mind. Because fMRI signals are an indirect measure of neural activity, interpreting these signals to make deductions about the nervous system requires some understanding of the signaling mechanisms. We describe our current und...
