“The more we probe the brain’s workings, the more we realise that our conscious minds are really just a summary of what our brains get up to all the time – without “us” having any idea. As Eagleman puts it, “The conscious you, which is the part that flickers to life when you wake up in the morning, is the smallest bit of what’s happening in your head….It’s like a broom closet in the mansion of the brain.”
