Spontaneous Slow Hemodynamic Oscillations are Impaired in Cerebral Microangiopathy

Journal of Cerebral Blood Flow & Metabolism (2005) 25: 1675-1684. doi:10.1038/sj.jcbfm.9600159

Following the publication of this article, the authors discovered the following error: Table 3 reports correlations between the power spectral density of spontaneous slow hemodynamic oscillations, severity of cerebral microangiopathy, as assessed with magnetic resonance imaging scans, and neuropsychological deficits. The correlation analysis was not perrformed for very-low-frequency oscillations (VLFOs) for stimulation and rest separately, as indicated in Table 3. Instead, correlation values are shown for the difference of VLFOs between stimulation and rest (stimulation—rest) for oxy- and deoxy-hemoglobin separately, as it is described in Results section.
