A neurologist looks at mind and brain: "the enchanted loom".

For a long time, before we developed an appreciation of the neuroanatomy and neurophysiology of the brain, there was uncertainty as to the nature and source of the human mind. Philosophers linked the mind to mythical "humors" that controlled the human body, and others speculated that the mind was associated with "life-force" or soul. Few felt that there was a relation between the human mind and brain, but they had to wait for the Age of Enlightenment and scientific discovery in the 18th and 19th centuries to establish a clear association between the two.

Neurologic conditions: assessing medical fitness to drive.

Clinicians are often asked to make an assessment on whether a patient is medically fit to drive, even though few have been formally trained in this area. Driving is a complex task that requires having adequate operational, cognitive and higher executive functions that work together. These functions can be compromised to a greater or lesser extent in neurological disorders, such as stroke, traumatic brain injury, peripheral neuropathy, dementia, Parkinson's disease and epilepsy.
