This is a very readable account by someone with a brain tumour, about what it is like to be on the receiving end of various brain scanning techniques. Harry Stawson has a tumour in his right temporal lobe. He is left handed. The surgeons need to find out where the “eloquent” areas of his cortex – the parts responsible for language – reside in his slightly non-standard brain.
We tend to regard brain-scanning as a rather dry and academic topic, full of long biological words that are difficult to revise. This short article brings it down to earth in a very humane way.
You will have to go to a proper library to track down this issue of the London Review of Books.

In biopsych we learn that speech production and speech recognition are highly localised. Neuropsychologist Jack Gallant has peered into the brains of volunteers while they listen to podcasts, and finds that speech comprehension is actually much more interesting than the textbook would lead you to believe.
“when you’re listening to someone tell an interesting story, an enormous swath of your brain is being activated.”
This is Your Brain on Podcasts.
Read. This. Book.
This one is in my top three psychology books for A level students to read this year. It is exciting because it sketches out some future directions that cognitive neuroscience is going to take in the coming years and decades.
When Galileo pointed his telescope at the night sky, he saw for the first time the machinery of planetary motion. This laid the foundations for our modern understanding of astronomy. The same is happening today in brain science. The ongoing improvement in brain scanning is driving new understanding of how the brain actually works. This book is a guide to the road ahead.
Not only that, but the first few chapters are a brilliant primer on the basics of neuroscience and biopsychology, and will be great revision for this part of the exam.
A really interesting read, and very accessible.
“A connectome is the totality of connections between the neurons in a nervous system.”
“In the nineteenth century, the American psychologist William James wrote eloquently of the stream of consciousness, the continuous flow of thoughts through the mind. But James failed to note that every stream has a bed. Without this groove in the earth, the water would not know in which direction to flow. Since the connectome defines the pathways along which neural activity can flow, we might regard it as the streambed of consciousness.
The metaphor is a powerful one. Over a long period of time, in the same way that the water of the stream slowly shapes the bed, neural activity changes the connectome. The two notions of the self – as both the fast-moving, ever-changing stream and the more stable but slowly transforming streambed – are thus inextricably linked. This book is about the self as the streambed, the self in the connectome – the self that has been neglected for too long.”
Multi tasking is not actual multi tasking. It is switching attention from one task to another very quickly. Our brains are bad at doing this, and the more we do it the less well we perform. It is better to concentrate on one thing at a time. This book explains why, and gives practical strategies based on sound scientific psychology that will help you to concentrate better and to remember more.
It explains why we find decisions harder if there are too many choices, and how to tackle that problem. It gives practical advice on how not to forget things, how not to run out of time, and how to use logic to make tough decisions, and not to be swayed by irrational emotions.
It also puts forward some ideas for education. What is the point of learning stuff when we can just google everything? The book explores what we should be learning, when everything is just a click away.
Really readable and packed with excellent (and commendably scientific) background psychology.
The “Silent Land” in question is the brain. Paul Broks is a neuropsychologist, who spends his days talking to and helping people with brains damaged by stroke, injury, or other trauma. They are altered – the same person, but permanently changed. Broks helps these people and their families come to terms with the injuries, and at the same time speculates on how the Silent Land can give rise to our humanity.
The book is a series of case studies: frank and humane discussions with brain damaged people, very readable, and not at all technical. By looking at how focussed damage to particular brain areas gives rise to specific cognitive deficits, Broks addresses the questions of localisation of function in the brain, and asks the larger question: how does this dark and tangled web of synapses and neurons in our skull conjure up a person?
