Glutamate and GABA are the main information carrying neurotransmitters in the brain. Their action is modulated by a further series of small molecules called neuromodulators. The major neuromodulators in the brain are acetylcholine (both muscarinic and nicotinic), dopamine, norepinephrine, epinephrine and serotonin. These have an enormous range of functions in a wide variety of brain mechanisms. This book attempts to give a general overview of this field with a section devoted to each of these. Each section starts with anatomy, both structural and functional. The various types of receptors for...

In the 18th Century a movement arose that believed that human problems could all be solved by the exercise of science and reason. This has led to enormous benefits for humankind. However, two malignant forces are threatening this advance. The first is composed of romantic intellectual and political movements-in particular fascism and communism-that arose out of the writings of philosophers and other intelligentsia in the 19th Century. The second is the epidemic of nihilism sweeping the world today. This book examines the roots of these threats to Civilization.

The present day is witnessing an explosion of our understanding of how the brain works at all levels, in which complexity is piled on complexity, and mechanisms of astonishing elegance are being continually discovered. This process is most developed in the major areas of the brain, such as the cortex, thalamus, and striatum. The Claustrum instead focuses on a small, remote, and, until recently, relatively unknown area of the brain. In recent years, researchers have come to believe that the claustrum is concerned with consciousness, a bold hypothesis supported by the claustrum's...
