چکیده
Figure 3. Left: Fitted RRFs for the average timecourse of 9 subjects (color) compared with the RRF in response to a single deep breath [1] (black), plotted as %BOLD versus scan volume. Center: Manual alteration of the a2 parameter of the original RRF [1] (2a2 and 3a2, black lines) suggests this parameter explains much of the difference in response dynamics. Right: Boxplots of fitted parameter values for nine subjects compared with the original parameter values (green). Figure 4. Below: CVR (%BOLD) and temporal parameter maps for one subject.

Blood pressure changes induced by arterial blood withdrawal influence bold signal in anesthesized rats at 7 Tesla: implications for pharmacologic mri.
Functional magnetic resonance imaging (fMRI) using the blood oxygenation level-dependent (BOLD) contrast is now increasingly applied for measuring drug effects on brain activity. A possible confound in pharmacologic fMRI (phMRI) is that the BOLD signal may be sensitive to systemic cardiovascular or respiratory parameters, which can themselves be modulated by a drug. To assess whether abrupt cha...
متن کاملAdvances in High-Field BOLD fMRI
This review article examines the current state of BOLD fMRI at a high magnetic field strength of 7 Tesla. The following aspects are covered: a short description of the BOLD contrast, spatial and temporal resolution, BOLD sensitivity, localization and spatial specificity, technical challenges as well as an outlook on future developments are given. It is shown that the main technical challenges o...
متن کاملRapid Communication Spatial dependence of the nonlinear BOLD response at short stimulus duration
Most functional magnetic resonance imaging studies use linear models to predict the measured response by convolution of an impulse response with the stimulus profile. Using very short visual presentation times ( 2 s), deviation from the linear model in the measured BOLD data from the human brain was found for the response integral, amplitude, and width. In this study, high temporal and spatial ...

متن کاملImaging brain function in humans at 7 Tesla.
This article describes experimental studies performed to demonstrate the feasibility of BOLD fMRI using echo-planar imaging (EPI) at 7 T and to characterize the BOLD response in humans at this ultrahigh magnetic field. Visual stimulation studies were performed in normal subjects using high-resolution multishot EPI sequences. Changes in R(*)(2) arising from visual stimulation were experimentally...
