Automatic segmentation of chronic stroke lesion from magnetic resonance images (MRI) is motivated by the increasing need for reproducible and repeatable endpoints in clinical trials. The task is non-trivial, due to a number of confounding factors, including heterogeneous lesion intensity, irregular ...
Neural stem cells (NSCs) play vital roles in brain homeostasis and exhibit a broad repertoire of potentially therapeutic actions following neurovascular injury. One such injury is stroke, a worldwide leading cause of death and disability. Clinically, ext
a, Magnetic resonance imaging (MRI) overlayed by PET from a 58-year-old male participant with a right hemisphere stroke lesion. The ipsilesional motor-associated cortical regions are identified as: primary motor (M1), fuchsia; primary somatosensory (S1), green; pre-supplementary area (pre-SMA...
Another limitation lies in the concurrent use of rTMS and regular physiotherapy in our patient population. Both interventions have been shown to modulate recovery, even in chronic stroke [88]. Consequently, the effects observed in our study cannot be solely attributed to rTMS but rather to the co...

Lesion overlap maps of all adults with stroke (n = 11; One had no brain MRI data and was not included in the lesion analysis) showed that the highest lesion overlap was in the insula (n = 8) (see Fig. 5A). When overlaying the MRIs of adults with stroke that exhibited posi...
