Your brain is a tough nut to crack. Psychologists have been trying to understand what’s inside our heads for over a century (which actually isn’t very long, as science goes), and there are still gaping cavities at the roots of our models. We have a pretty good understanding of how each of our senses work – how we see, touch, feel, hear and smell – but not so much how we generate consciousness – our sense of being. We have some sound models of what happens when we try to remember something, but no definitive picture of how those memories are created, or encoded, in the first place. This, in the face of our understanding of the rest of the Universe – of black holes, of distant worlds, of our own genetic code and so on – seems a bit disappointing.
It’s so disheartening in fact, that there’s even a school of thought that says we might never be able to fully understand the brain. There’s just too much navelgazing going on; in other words, our brains might be too limited to ever really understand how they do what they do.
I’m mentioning all this, not because I’m having another existential crisis (I save those for the holidays) but because May is Mental Health Awareness month around the world. This inspired us to devote a whole issue’s worth of features to the subject. But as we debated which stories we could fit on our pages, it became clear just how much we still don’t understand about what happens when our minds – the product of our brains – get ill. That said, this issue has taught me one thing for sure: that we’re happier and healthier when we’re together (p58), which is nice. So in that spirit, we hope you enjoy the issue and find someone to share it with.
