Blocking Assay:Article Title: Robustly measuring vascular reactivity differences with breath-hold: normalising stimulus-evoked and resting state BOLD fMRI data. Article Snippet: Article history: Received 27 April 2010 Revised 6 July 2010 Accepted 26 July 2010 Available online 1 August 2010 Inter-subject differences in local cerebral blood flow (CBF) and cerebral blood volume (CBV) contribute to differences in BOLD signal reactivity and, therefore, unmodelled variance in group level fMRI analyses.. A simple way of elevating blood CO2 concentrations to characterise subject differences in vascular reactivity is through breath-holds but two aspects of this measure are often neglected: (1) breath-holds are usually modelled as blocks even though CO2 accumulates over time and (2) increases in CO2 differ between subjects.. This study demonstrates that the BOLD breath-hold response is best modelled by convolving the end-tidal CO2 trace with a standard haemodynamic response function and including its temporal derivative.
