Just finished reading this book…really enjoyed it…

 

Extract from Amazon.com

The brain has been the last “terra incognita” of the body for medical exploration, largely because its matter is so different from that of the rest of the body. In 1986 the eminent evolutionary biologist John Maynard Smith identified the problem of how the brain works as one of the two outstanding problems in biology (along with how a simple egg develops into a complex adult organism). Most of us have experienced some apparently inexplicable quirk of the mind, such as selective memory loss. Without obvious “hard wiring”, anatomical “labels” or other guiding features, medical scientists have struggled to identify its parts, their functions and connections to the mind. Not that this has stopped curiosity; there is anthropological evidence dating back some thousands of years for crude but sometimes successful attempts to open the skull and get at the brain.

Rita Carter is an award-winning medical writer. (Medical Journalists’ Association prize for outstanding contribution). In Mapping the Mindshe explores the landscape of the brain and its connections with the mind. We should all be enthralled by this adventure for “it is giving us greater understanding about one of the oldest and most fundamental of mysteries–the relationship between the brain and mind”. Carter introduces the subject with the historical background of anatomical discoveries and emerging theories of brain/mind connections. The famous tragic story of the 19th-century American railway worker, Phineas Gage, is here. An iron rod blasted through poor Phineas’s skull. It entered below his left eye and exited through his skull roof, removing a large chunk of his forebrain. Amazingly, Phineas survived but his personality was radically changed, as was reported by his doctor, John Harlow.

 

In this fascinating and well-illustrated book, Rita Carter shows just how far we have travelled in our understanding since the mid-19th century world of Dr Harlow and gives a sense of how far we still have to travel. As she says: “The world within our heads is more marvellous than anything we can dream up”. The last few decades have seen a revolution in non-invasive brain mapping thanks to the scientific miracles of Magnetic Resonance Imaging and associated technologies. It is now possible to see which part of the brain responds to specific stimulation in real time.
