‘Breaking down the walls’: therapeutic bypassing of the blood-brain barrier

By Samrah Siddiqi Often naively thought of as the wall which protects our brains, the blood-brain barrier (BBB) is a complex physiological barrier comprising a multitude of endothelial cells lining blood vessels.

The voiceless narration of a life: what is it like to not have an inner monologue?

By Effie Eshetu “Please be quiet, I can’t hear myself think!” This colloquial saying sounds completely logical to most of us. However, to others, upon a little dissection, it may seem semantically dissonant, and even nonsensical. This is because some individuals actually cannot, regardless of how quiet the room is, hear themselves think (Epting, 2020).Continue reading “The voiceless narration of a life: what is it like to not have an inner monologue?”
