Deja vu’s lesser-known opposite: why do we experience jamais vu?

There’s a sensation many of us might have experienced: when
something routine or recognisable suddenly feels strange and
unfamiliar. It’s known as jamais vu, or ‘never seen’. Research into
this odd feeling recently won an Ig Nobel prize, which is awarded
to science that makes you laugh, then think. Ian Sample speaks to
Ig Nobel recipient Dr Akira O’Connor about why he wanted to study
jamais vu, what he thinks is happening in our brains, and what it
could teach us about memory going right, and wrong. Help support
