Quantitative aspects of brain perfusion dynamic induced by BOLD fMRI Aspectos quantitativos da dinâmica perfusional do cérebro induzida pelo BOLD fMRI

The increase of relative cerebral blood flow (rCBF) may contribute for a change in blood oxygenation level dependent signal (BOLD). The main purpose of this study is to investigate some aspects of perfusional alterations in the human brain in response to a uniform stimulation: hypercapnia induced by...
