Parad 1 and 2: Language paradigm 1 and 2 respectively; Ex 1 and Ex 2: days from stroke onset; NIHSS NIH stroke scale at the first examination time (Ex 1) and at the second examination time (Ex 2); TTP: time to peak expressed in seconds and Ampl: Peak Amplitude of BOLD.; AH: affected hemisphere, UH: unaffected hemisphere; CBFV: mean MCA cerebral blood flow velocity expressed in cm/s; Mx index: correlation coefficient between CBFV and arterial blood pressure; Mean (SD): mean values (Standard deviation); in the bottom raw p values for comparison of each measure from Ex 1 to Ex 2 are reported, and evidenced in bold in case of statistical significance.
