What is the BOLD response

The BOLD Response • Changes in cerebral blood flow (CBF) drive the BOLD changes -Temporal characteristics of the CBF changes dominate the BOLD temporal response (Hoge RD, et al. Magn. Reson. Med. 1999; 42:849-863.) BOLD and CBF changes with graded hypercapnia and visual stimulation (Miller KL, et al. Human Brain Mapping 2001; 13:1-12. The BOLD response is clearly an essential component of normal brain function (Girouard & Iadecola 2006, Mogi & Horiuchi 2011, Schroeter et al. 2007), yet its relationship to neuronal metabolism is less clear The BOLD response during Stroop task-like inhibition paradigms: Effects of task difficulty and task-relevant modality.

BOLD contrast blood flow blood volume oxygen utilization structural lesions (compression) autoregulation (vasodilation) cerebrovascula consumption accompanied by a large change of oxygenated blood flow Ratio of oxygenated blood to deoxy increases with neuronal activity Results in decreased magnetic susceptibility and increased fMRI signal BOLD= Blood oxygenation level dependent signal (BOLD) CEA/SHFJ 26/09/04 4/4 Deconvolution of the BOLD response showed that the estimation of the neural response is relatively accurate for low temporal frequencies (up to 0.16 Hz). Increasing temporal frequency strongly increased the residuals. For stimulation frequencies >0.21 Hz, reconstruction of the neural response was no longer possible

The overall BOLD response (blue) is a moving average of the individual HRFs outlined in black, red, and green. The vertical black lines on the x-axis represent impulse stimuli. Figure created by Bob Cox of AFNI. Putting it all together: Animations of each Case The most common functional imaging signal is the blood-oxygen-level dependent signal (BOLD), which primarily corresponds to the concentration of deoxyhemoglobin Blood oxygenation level dependent (BOLD) imaging is the standard technique used to generate images in functional MRI (fMRI) studies, and relies on regional differences in cerebral blood flow to delineate regional activity. Blood flow in the brain is highly locally controlled in response to oxygen and carbon dioxide tension of cortical tissue The regional BOLD response generated from a brief peripheral stimulus (such as a flashing light or pin prick) is known as the Hemodynamic Response Function (HRF). The HRF typically demonstrates a small initial dip, followed by a tall peak, and then a variable post-stimulus undershoot.
