Written by one of the world’s leading neuroscientists, Making Up the Mind is the first accessible account of experimental studies showing how the brain creates our mental world.
- Uses evidence from brain imaging, psychological experiments and studies of patients to explore the relationship between the mind and the brain
- Demonstrates that our knowledge of both the mental and physical comes to us through models created by our brain
- Shows how the brain makes communication of ideas from one mind to another possible

Threatening forms. They were in continuous motion, animated, as if driven by an inner restlessness.18 18 The psychological effects of LSD were discovered by accident in 1943. A small amount of the drug soaked through the fingers of research chemist Albert Hoffman during a routine synthesis. During the following weeks he explored the effects of the drug and kept detailed notes, such as those cited here and in the previous extract. 36 Seeing through the Brain’s Illusions I noticed that the.
Began to think my eyes had played me a trick; so I resumed my search in as nearly as possible the same position as before, and having succeeded, was turning to come away when lo! and behold! there sat the little old lady as distinct as ever, with her funny little cap, dark dress, and hands folded demurely over her white handkerchief. This time I turned round quickly and marched up to the apparition. Which vanished as suddenly as before. 58 Seeing through the Brain’s Illusions So the effect.
Most active. If we are using our ears, then the most active part of the brain will be two regions at the side where neurons receive messages directly from the ears (see Figure CP2, color plate section). When the neurons in this region are active, there will also be greater local supply of blood. This relationship between brain activity and local changes in blood flow was known to physiologists for more than 100 years, but it was not possible to detect the changes in blood flow until brain scanners.
Become more variable. This was a sign of the brain’s automatic tendency to imitate the actions of others. But if a robot arm was making the movements, then this did not interfere with the observer’s movements. The brain does not automatically imitate a robot arm, because the movements of this arm are subtly wrong; we see them as mechanical rather than biological. The robot arm is not perceived as an agent with goals and intentions. When a robot arm moves, my brain sees only movements, not.
The blood supply to the back of his brain. It was possible to hear the change in blood flow in the visual area of his brain as he opened and closed his eyes. 10 Prologue A few nerve cells with their fibers nerve cell bodies connecting fibers Figure p.4 Cortex and cells The cortex under the microscope showing three different aspects of nerve cells.
