Neurological marginalia: purposes and practicalities

Marginalia, or apostils, are defined as notes, comments or other markings made in the margins of a book or document. As a reader who has habitually added markings and comments to such documents over many years, I offer some thoughts on the purposes of marginalia added to neurological texts. I also include some practical recommendations on how readers might construct marginalia. Rather than merely personalising a text, marginalia may have the capacity to foster systematic reading and critical thinking and may facilitate the process of writing.
