Neuroscientist Robert Martone tells us,

A new study, published in the journal Social Cognitive and Affective Neuroscience(SCAN), explores how a specific brain region helps knit together memories of the present and future self. Injury to that area leads to an impaired sense of identity. The region—called the ventral medial prefrontal cortex (vmPFC)—may produce a fundamental model of our self and place it in mental time. In doing so, this study suggests, it may be the source of our sense of self.

This is nonsense, of course. A kitten has a sense of self if you try holding on to its tail. But so does a fly if you try holding onto its wing. Does the fly really have a ventral medial prefrontal cortex (vmPFC)? Is vmPFC really necessary to a sense of injury to self?

We live in a strange world but it is not so strange as all that.
