We believe that research into the human brain is the flip side of research into Artificial Intelligence. As the two will one day coincide, the more we know about both the better. So when Nature Briefing, that go-to Record for all things new and scientific, puts out not one but two (two, folks!) stories on the human brain, we felt it our solemn duty to bring you them both.
We have always believed that scaring people into doing things is counter-productive in the long term. Our worse fears are confirmed by this piece called Stress stops the Brain Joining the dots.
Acute stress makes it difficult to connect memories of past experiences with fresh information — a process crucial for making deductions. This could explain why people struggle to show insight under pressure. During psychological tests that involved making links between indirectly related pictures, brain imaging showed altered activity in the hippocampi of people who had been through a stressful mock interview compared with those of people who’d had to complete a simpler task, which suggests that their brains hadn’t inferred connections between the images as strongly.

Every epoch casts reality in its own image The Victorians though that everything in the world worked like a steam engine. Around 1910 they thought all was electric circuits. And Cold war people put us all down as computers. Every picture of the brain is an analogue, an attempt only as this piece The Brian is no machine makes clear.
In The Brain, In Theory, neuroscientist Romain Brette makes the case to move away from the predominant model of the brain, which treats the organ like a computer. Brette argues that engineering metaphors are often vague and misleading, and attempts to breathe life back into brain science by focusing on the study of the nervous system on biology. “Brette’s take-down of the field’s dominant theoretical frameworks is systematic,” writes neuroscientist Àlex Gómez-Marín in his review. “The book is intense and intricate. One can get lost in it, but it is worth the adventure.”
So our advice is study both of the above with close attention, gentle reader. It’s a no-brainer!
