The barrel area is a unique specialization of the cerebral cortex, shared by many species of rodents and some marsupials, in which the somatotopic map of the body surface receives direct morphological expression. Here, the homogeneous sheet of layer IV granule cells seen in most mammals is fractured into large archipelagos, each representing one of the larger subdivisions of the contra lateral half-body. Within these larger domains are smaller aggregates of granule cells that contain the concentrated terminations of thalamocortical fibers bear ing messages emanating from constellations of receptors located in finer subdi visions of a body part. These smaller aggregates are particularly well-defined in the representation of the face, where they form a one-to-one representation of the sinus hairs or vibrissae and where they have been given the name barrels. The first inklings of the unique structure of the parietal cortex of rodents came in the study of Droogleever-Fortuyn (1914), who remarked on the pres ence in it of clouds of granule cells 0. 5-1 mm in diameter, which he thought were in some way associated with concentrations of nerve fibers. Little attention, however, was paid to his observations. Lorente de N 6 (1922) later observed dense focal concentrations of afferent fiber ramifications in Golgi preparations of the mouse cortex, calling them glomeruli, and these can now be seen as the structures that form the hearts of the barrels and around which the granule cells concentrate."

As the 2020s began, protestors filled the streets, politicians clashed over how to respond to a global pandemic, and new scrutiny was placed on what rights US citizens should be afforded. Newly revised and expanded to address immigration, gay rights, privacy rights, affirmative action, and more, The Bill of Rights in Modern America provides clear insights into the issues currently shaping the United States. Essays explore the law and history behind contentious debates over such topics as gun rights, limits on the powers of law enforcement, the death penalty, abortion, and states' rights. Accessible and easy to read, the discerning research offered in The Bill of Rights in Modern America will help inform critical discussions for years to come.

nerve; subsequently, however, they concluded that the recordings had been from aberrant cells of the cochlear nucleus lying central to the glial margin of the VIII nerve (GALAMBOS and DAVIS, 1948). The first successful recordmgs from fibres of the cochlear nerve were made by TASAKI (1954) in the guinea pig. These classical but necessarily limited results were greatly extended by ROSE, GALAMBOS, and HUGHES (1959) in the cat cochlear nucleus and by KATSUKI and co-workers (KATSUKI et at. , 1958, 1961, 1962) in the cat and monkey cochlear nerve. Perhaps the most significant developments have been the introduction of techniques for precise control of the acoustic stimulus and the quantitative analysis of neuronal response patterns, notably by the laboratories of KIANG (e. g. GERSTEIN and KIANG, 1960; KIANG et at. , 1962b, 1965a, 1967) and ROSE (e. g. ROSE et at. , 1967; HIND et at. , 1967). These developments have made possible a large number of quanti tative investigations of the behaviour of representative numbers of neurons at these levels of the peripheral auditory system under a wide variety of stimulus conditions. Most of the findings discussed herein have been obtained on anaesthetized cats. Where comparative data are available, substantially similar results have been obtained in other mammalian species (e. g. guinea pig, monkey, rat). Certain significant differences have been noted in lizards, frogs and fish as would be expect ed from the different morphologies of their organs of hearing (e. g.

Featuring both MCQs and EMQs, two of the key components of many postgraduate surgical examinations, this 2003 book is designed to be an accessible self-learning tool, and is the ideal companion to Fundamentals of Surgical Practice by Aljafri Majid and Andrew Kingsnorth. The questions provided are typical of those that appear in the MRCS/AFRCSEd and similar examinations and detailed answers, along with explanatory notes to assist the reader, are provided throughout. Each section is also further divided to reflect the topics covered in Fundamentals of Surgical Practice, and the answers are cross-referenced throughout to relevant sections of this key text, further enhancing the learning experience of the reader, who is able instantly to locate detailed information on the topic of interest.

Intelligence, surveillance and reconnaissance (ISR) is a high-demand Department of Defense mission performed by unmanned aircraft systems (UAS) at the tactical and theater levels. Coordinating UAS aircraft through cooperative control offers the advantages of persistence, distributed and adaptable sensor coverage, and reduced revisit time on points of interest. The purpose of this thesis is to apply systems engineering principals to the problem of developing a flexible, common control system for cooperative UAS surveillance at the tactical level. The AFIT team developed a concept of operations (CONOPS) encompassing various users and surveillance tasks. The team then used the scenarios in the CONOPS to build a conceptual architecture.
