Investigating neural correlates of stimulus repetition using fMRI
… effects in the human brain. However the Blood-Oxygenation Level-Dependent (BOLD) signal measured by fMRI is far removed from the electrical activity recorded from single cells in animal studies of repetition effects. Despite that, there have been many claims about the neural mechanisms …

Bridging Mri Reconstruction Across Eras: From Novel Optimization Of Traditional Methods To Efficient Deep Learning Strategies
… over conventional methods. Furthermore, the blood oxygenation level dependent (BOLD) signal analysis of our proposed method provided meaningful sensitivities, with similar activation patterns and extent to the expected baselines.

Cardiorespiratory fitness as a modulator of hippocampal subfield structure and function in cognitive aging
… humans. Age-related impairment in hippocampally-dependent cognition emphasizes the importance of identifying modulators of hippocampal plasticity. Critically, studies in older adults have demonstrated that greater cardiorespiratory fitness (CRF) is associated with greater volume of the …

Correcting the variations of bold signal due to susceptibility-induced magnetic field gradients and its application
… magnetic resonance imaging (fMRI) using blood oxygenation level dependent (BOLD) signals is a tool that is currently used in many cognitive neuroscience studies. However, many studies do not consider susceptibility-induced magnetic field gradients. Susceptibility-induced magnetic field …
