Book Description
Monakow (1882) recognized in the medial geniculate body (MGB) a medial or "magnocellular", and a lateral, "principal" or parvicellular part. The latter was further subdivided by Cajal (1902) in a dorsal and a ventral lobe. Monakow's division was adopted by Rioch (11:)29) and has been widely used. Morest (1964), in a Golgi study in the cat, used Cajal's scheme and further subdivided the ventral division into several subnuclei. Morest considered Cajal's suprageniculate nucleus as apart of the MGB. The cortical projections of the MGB in the cat were studied by Woollard and Harpman (1939) and Ades (1941) with the Marchi method and, more recently, by Wilson and Gragg (1969) using the Nauta method. While all these studies show MGB projections to the first auditory area (AI) as electrophysiologically defined (Woolsey, 1960), there is disagreement as to the existence and extent of MGB projections to other cortical areas (All, AIll, Ep, Ea and SF of Woolsey, 1960) where auditory activity has been electrophysiologically demonstrated. These studies did not disclose topical relationships between the different subdivisions of the principal MGB and the various cortical projection areas.

Book Description
In the operation of reasoning, the mind does nothing but run over its objects, as they are supposed to stand in reality, without adding any thing to them or diminishing any thing from them. If I examine the Ptolomaic and Copernican systems, I endeavour only, by my inquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relation that they bear towards each other in the heavens. To this operation of the mind, therefore, there seems to be always a real, though often unknown standard, in the nature of things; nor is truth or falsehood variable by the various apprehensions of mankind.

The Anatomical Organization of the Suprasylvian Gyrus of the Cat

Pages : 63
Book Description
In recent years, the suprasylvian gyrus of the cat has attracted the attention of many neurophysiologists and experimental psychologists and the variety of their interests is reflected in the number of morphological and functional sub divisions which have been made of it. Some of these subdivisions are shown in Fig. 1. Workcrs concerned with t. hc visual system havc made studies of the third visual area (awa to) on the medial aspect. of thc gyrus, and of the latcral supra sylvian area on the lateral aspeet, both of which contain representations of the retina (Clare and Bishop, 1954; Hubel and Wiesel, 1965, 1969; Wright, 1969). However, the full extent of these areas and particularly of the latter, is still not known. Other workers have investigated the extent of the gyrus activated by somatic sensory (Darian. Smith, Isbister, Mok and Yokota, 1966) or auditory (Woolsey, 1961) stimuli. A third field of incrcasing interest is the study of the "polysensory areas" of the cortex, two of which are situated in the middle supra sylvian gyrus. In these areas, in animals anaesthetized with chloralose, conver gence upon single neurons of auditory, somatic and visual impulses has been demonstrated (see ego Thompson, Johnson and Hoopes, 1963; Dubner and Rut ledge, 1964, 1965; Dubner, 1966; Bignall, 1967) and it has been proposed that these areas play an important part in the central processing of sensory information (Buser and Bignall, 1967; Thompson, 1967).
Functional Organization of the Cat's Dorsal Lateral Geniculate Nucleus

ISBN: 0387270833
Category : Science
Languages : en
Pages : 720
Book Description
Connecting the auditory brain stem to sensory, motor, and limbic systems, the inferior colliculus is a critical midbrain station for auditory processing. Winer and Schreiner's The Inferior Colliculus, a critical, comprehensive reference, presents the current knowledge of the inferior colliculus from a variety of perspectives, including anatomical, physiological, developmental, neurochemical, biophysical, neuroethological and clinical vantage points. Written by leading researchers in the field, the book is an ideal introduction to the inferior colliculus and central auditory processing for clinicians, otolaryngologists, graduate and postgraduate research workers in the auditory and other sensory-motor systems.
The Auditory Cortex

ISBN: 1441900748
Category : Science
Languages : en
Pages : 711
Book Description
There has been substantial progress in understanding the contributions of the auditory forebrain to hearing, sound localization, communication, emotive behavior, and cognition. The Auditory Cortex covers the latest knowledge about the auditory forebrain, including the auditory cortex as well as the medial geniculate body in the thalamus. This book will cover all important aspects of the auditory forebrain organization and function, integrating the auditory thalamus and cortex into a smooth, coherent whole. Volume One covers basic auditory neuroscience. It complements The Auditory Cortex, Volume 2: Integrative Neuroscience, which takes a more applied/clinical perspective.
