Principles of Neural Science, Fifth Edition (Principles of Neural Science (Kandel)) : Medicine & Health Science Books @ aracer.mobi Editorial Reviews. About the Author. McGraw-Hill authors represent the leading experts in their The book Principles of Neural Science by Kandel et. al. has been a fantastic compliment to the class I'm currently enrolled in at Iowa State.
Abulcasis , Averroes , Avicenna , Avenzoar , and Maimonides , active in the Medieval Muslim world, described a number of medical problems related to the brain. The Golgi stain first allowed for the visualization of individual neurons.
Luigi Galvani 's pioneering work in the late s set the stage for studying the electrical excitability of muscles and neurons.
In the first half of the 19th century, Jean Pierre Flourens pioneered the experimental method of carrying out localized lesions of the brain in living animals describing their effects on motricity, sensibility and behavior. In Emil du Bois-Reymond demonstrated the electrical nature of the nerve signal,  whose speed Hermann von Helmholtz proceeded to measure,  and in Richard Caton found electrical phenomena in the cerebral hemispheres of rabbits and monkeys.
The procedure used a silver chromate salt to reveal the intricate structures of individual neurons. In parallel with this research, work with brain-damaged patients by Paul Broca suggested that certain regions of the brain were responsible for certain functions.
At the time, Broca's findings were seen as a confirmation of Franz Joseph Gall 's theory that language was localized and that certain psychological functions were localized in specific areas of the cerebral cortex. Carl Wernicke further developed the theory of the specialization of specific brain structures in language comprehension and production. Modern research through neuroimaging techniques, still uses the Brodmann cerebral cytoarchitectonic map referring to study of cell structure anatomical definitions from this era in continuing to show that distinct areas of the cortex are activated in the execution of specific tasks.
Schmitt , and Stephen Kuffler as having played critical roles in establishing the field. During the same period, Schmitt established a neuroscience research program within the Biology Department at the Massachusetts Institute of Technology , bringing together biology, chemistry, physics, and mathematics.
The first freestanding neuroscience department then called Psychobiology was founded in at the University of California, Irvine by James L. For example, in , Alan Lloyd Hodgkin and Andrew Huxley presented a mathematical model for transmission of electrical signals in neurons of the giant axon of a squid, which they called " action potentials ", and how they are initiated and propagated, known as the Hodgkin—Huxley model.
In —, Richard FitzHugh and J. In , Bernard Katz modeled neurotransmission across the space between neurons known as synapses. Beginning in , Eric Kandel and collaborators examined biochemical changes in neurons associated with learning and memory storage in Aplysia. Such increasingly quantitative work gave rise to numerous biological neuron models and models of neural computation. As a result of the increasing interest about the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientist during the 20th century.
For example, the International Brain Research Organization was founded in ,  the International Society for Neurochemistry in ,  the European Brain and Behaviour Society in ,  and the Society for Neuroscience in This has allowed neuroscientists to study the nervous system in all its aspects: how it is structured, how it works, how it develops, how it malfunctions, and how it can be changed. For example, it has become possible to understand, in much detail, the complex processes occurring within a single neuron.
Neurons are cells specialized for communication. They are able to communicate with neurons and other cell types through specialized junctions called synapses , at which electrical or electrochemical signals can be transmitted from one cell to another.
Many neurons extrude a long thin filament of axoplasm called an axon , which may extend to distant parts of the body and are capable of rapidly carrying electrical signals, influencing the activity of other neurons, muscles, or glands at their termination points. A nervous system emerges from the assemblage of neurons that are connected to each other.
The vertebrate nervous system can be split into two parts: the central nervous system defined as the brain and spinal cord , and the peripheral nervous system. In many species — including all vertebrates — the nervous system is the most complex organ system in the body, with most of the complexity residing in the brain. The human brain alone contains around one hundred billion neurons and one hundred trillion synapses; it consists of thousands of distinguishable substructures, connected to each other in synaptic networks whose intricacies have only begun to be unraveled.
At least one out of three of the approximately 20, genes belonging to the human genome is expressed mainly in the brain.
Ultimately, neuroscientists would like to understand every aspect of the nervous system, including how it works, how it develops, how it malfunctions, and how it can be altered or repaired. Analysis of the nervous system is therefore performed at multiple levels, ranging from the molecular and cellular levels to the systems and cognitive levels. The specific topics that form the main foci of research change over time, driven by an ever-expanding base of knowledge and the availability of increasingly sophisticated technical methods.
Improvements in technology have been the primary drivers of progress.
Developments in electron microscopy , computer science , electronics , functional neuroimaging , and genetics and genomics have all been major drivers of progress. Molecular and cellular neuroscience[ edit ] Main articles: Molecular neuroscience and Cellular neuroscience Photograph of a stained neuron in a chicken embryo Basic questions addressed in molecular neuroscience include the mechanisms by which neurons express and respond to molecular signals and how axons form complex connectivity patterns.
At this level, tools from molecular biology and genetics are used to understand how neurons develop and how genetic changes affect biological functions. The morphology , molecular identity, and physiological characteristics of neurons and how they relate to different types of behavior are also of considerable interest.
Questions addressed in cellular neuroscience include the mechanisms of how neurons process signals physiologically and electrochemically. These questions include how signals are processed by neurites and somas and how neurotransmitters and electrical signals are used to process information in a neuron.
