Excerpt from Synopsis of Lectures Upon Diseases of the Nervous System: Delivered at the College of Physicians and Surgeons, Medical Department of Columbia University, New York
The simplest form of a nervous system consists of a single mass of gray matter with a sensory and a motor nerve.
The mass of gray matter receives impulses sent from the surface by the sensory fibre, acts in response to the impulse, and the action is transmitted to a motor mechanism by the motor nerve.

Excerpt from Synopsis of Lectures Upon Diseases of the Nervous System: Delivered at the College of Physicians and Surgeons, Medical Department of Columbia University, New York
Examples. The nervous system of a frog experimentally deprived of its hemispheres, capable of automatic acts of swimming. The automatic act of respiration in man. In man the facial, laryngeal, intercostal, thoracic, and diaphragmatic respiratory muscles act in definite succession and rhythm in the act of breathing; and this act is presided over by a single centre in the medulla controlling the lower medullary and spinal centres.
The highest type of nervous system is the complex type. There are the lower centres as in the simple type. There are higher centres controlling the lower centres, as in the compound type. There is a supreme mass controlling both the others.
This is the form found in all vertebrates, and the degree of evolution in the highest or supreme mass determines the place of the animal in the scale of intelligence.
In man the supreme mass is the cerebral cortex, the next lower or automatic centres are the optic thalami and basal ganglia, including gray masses in the cerebral axis; the lowest or reflex centres are the cranial nerve nuclei in the cerebral axis and the gray matter of the spinal cord segments.
These distant gray masses are joined with one another in all possible combinations by means of the white nerve tracts, which pass in all directions around and within them.
The human nervous system consists of a peripheral system and a central system.
The peripheral system comprises all the nerves.
The central system includes:
First. The spinal cord and cranial nerve nuclei.
Secondly. The cerebellum; gray masses of the medulla, pons, and crura cerebri; corpora quadrigemina, optic thalami, and corpora striata.
Thirdly. The cerebral cortex.

Paperback. Condición: New. Print on Demand. This book explores diseases of the nervous system, providing a comprehensive examination of neurological conditions. The author presents a detailed analysis of the structure and functions of the central nervous system, tracing the evolution of this intricate system through different stages of complexity. The book delves into the composition of neurones, the primary elements of the nervous system, and their roles in transmitting impulses and controlling various bodily functions. It goes on to explore the peripheral nerves, their structure, and the impact of injuries or trauma on their function. The book also covers multiple sclerosis, highlighting the various forms of this chronic disease that affects the brain and spinal cord. Furthermore, the author discusses the causes, symptoms, and diagnosis of anterior poliomyelitis, a viral infection that can lead to paralysis, as well as the pathology and clinical features of syringomyelia, a rare condition characterized by a cavity within the spinal cord. The book concludes with an examination of amyotrophic lateral sclerosis, a progressive disease affecting the motor system, providing valuable insights into its diagnosis and management. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
