Endogenous Peptides and Learning and Memory Processes presents the role of pituitary and central nervous system peptidergic systems in the modulation of memory and learning. This book discusses the various experimental findings concerning the role of peptides in attention, memory, conditioning, opiate tolerance, and amnesia. Organized into five parts encompassing 26 chapters, this book starts with an overview of the possible chemical relationship between melanocyte-stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH). This text then discusses the complex behavioral activities of ACTH involving processes that serve the adaptive abilities of the organism, such as memory, learning, ...
First published in 1982. During the past fifty years, dramatic changes have occurred in the use of laboratory animals to study learning and memory. Yet the basic reasons for this research, diverse as they are, have not changed. At one extreme is the need for relatively direct application of findings with animal models to medical or educational problems of humans; at the other extreme, the quest for understanding animal behavior for its own sake. It is probably fair to say that no chapters in this book represent either of these extremes, although in each case the author’s purposes can be said to be like those of some scientists working in this area fifty years ago. In contrast to this continuity of purpose, the approach that scientists now take in this area of study is really quite different from that of most or all scientists in the 1930s.
A study was made to determine the effects of vestibular damage or previous vestibular stimulation on the spontaneous activity of the rat during rotation. Unilateral destruction of the labyrinth through intratympanic injections of streptomycin sulfate decreased the sensitivity of unrestrained rats to rotation, as measured by the maintenance of high levels of spontaneous locomotor activity during rotation. Repeated exposure to rotation produced a similar threshold shift in undamaged rats. Normal control animals showed a marked decrement in activity while rotated. Rats were extremely resistant to streptomycin sulfate injected systemically; neither morphological damage to hair cells nor changes in the response to vestibular stimulation was found following a total dosage of 10,000 mg of the drug. The findings demonstrated that the spontaneous activity levels provide a sensitive behavioral measure of the effects of vestibular stimulation on the rat. (Author).
Over the past century, educational psychologists and researchers have posited many theories to explain how individuals learn, i.e. how they acquire, organize and deploy knowledge and skills. The 20th century can be considered the century of psychology on learning and related fields of interest (such as motivation, cognition, metacognition etc.) and it is fascinating to see the various mainstreams of learning, remembered and forgotten over the 20th century and note that basic assumptions of early theories survived several paradigm shifts of psychology and epistemology. Beyond folk psychology and its naïve theories of learning, psychological learning theories can be grouped into some basic ca...
Conditioned taste aversion is arguably the most important learning process that humans and animals possess because it prevents the repeated self-administration of toxic food. It has not only profoundly influenced the content and direction of learning theory, but also has important human nutritional and clinical significance. In addition to its direct relevance to food selection, dietary habits, and eating disorders, it is significant for certain clinical populations that develop it as a consequence of their treatment. The study of conditioned taste aversions has invigorated new theory and research on drug conditioning and addictions, as well as on conditioned immunity. There has also been a ...
