Here we describe the standard protocol for the detection of β-galactosidase activity in early whole mouse embryos and the method for paraffin sectioning and counterstaining. This is an easy and quick procedure to monitor gene expression during development that can also be applied to tissue sections, organs or cultured cells.

This study presents a novel transcranial direct current stimulation (tDCS) protocol combined with cognitive stimulation to address post-stroke hemispatial neglect. Initial data from a pilot patient ensure the procedure's feasibility and suggest potential efficacy, providing a foundation for a future parallel, triple-blind, controlled clinical trial.
