I'm curently reading The River of Conciousness by Oliver Sacks.
Sacks is best known for his books: The Man Who Mistook His Wife For A Hat and Awakenings which was the basis for the 80's movie of the same name.
This book was outlined by him a few weeks before his death and consists of his musings on the evolution of the regions of the human brain which govern our perception of reality including time and movement. He branches into case studies of people with perceptual issues resulting from brain trauma, such as than inability to perceive objects in three dimensions or objects in motion as anything more than still images suddenly appearing in space.
It's pretty interesting for the most part
