Functional imaging studies of neurologically intact adults have demonstrated that the right posterior cerebellum is activated during verb generation, semantic processing, sentence processing, and verbal fluency. Studies of patients with cerebellar damage converge to show that the cerebellum supports sentence processing and verbal fluency. However, to date there are no patient studies that investigated the specific importance of the right posterior cerebellum in language processing, because: case studies presented patients with lesions affecting the anterior cerebellum, and group studies combined patients (...) with lesions to different cerebellar regions, without specifically reporting the effects of right posterior cerebellar damage. Here we investigated whether damage to the right posterior cerebellum is critical for sentence processing and verbal fluency in four patients with focal stroke damage to different parts of the right posterior cerebellum. We examined detailed lesion location by going beyond common anatomical definitions of cerebellar anatomy, and employed a recently proposed functional parcellation of the cerebellum. All four patients experienced language difficulties that persisted for at least a month after stroke but three performed in the normal range within a year. In contrast, one patient with more damage to lobule IX than the other patients had profound long-lasting impairments in the comprehension and repetition of sentences, and the production of spoken sentences during picture description. Spoken and written word comprehension and visual recognition memory were also impaired, however, verbal fluency was within the normal range, together with object naming, visual perception and verbal short-term memory. This is the first study to show that focal damage to the right posterior cerebellum leads to language difficulties after stroke; and that processing impairments persisted in the case with most damage to lobule IX. We discuss these results in relation to current theories of cerebellar contribution to language processing. Overall, our study highlights the need for longitudinal studies of language function in patients with focal damage to different cerebellar regions, with functional imaging to understand the mechanisms that support recovery.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 97 Unity and Reform: Selected Writings of Nicholas de Cusa. Edited by John P. Dolan. (Notre Dame, Indiana: University of Notre Dame Press, 1962. Pp. viii -I- 260. $6.50.) This volume was designed to serve both the cause of historical instruction and the cause of "unity and reform" as it has been stimulated by the present ecumenical movement and Council. Professor Dolan's Introduction emphasizes the practical aspects (...) of the Bishop's career, especially his efforts to combat the disintegration of the Respublica Christiana of the fifteenth century. He explains the Bishop's achievements, both ecclesiastical and philosophical, in terms of the problems of his own time. However, the reader soon discovers in the narrative of the Introduction as well as in the selections from Cusanus's works that the current revival of interest in this theologian and philosopher is due to the important bearing which he has on the Catholic efforts toward reunion and reform today. Only Book III of Learned Ignorance is included; then follow in their entirety Concerning Wisdom, The Vision of God or the Icon, Concerning Concord in Religious Belief (De Pace Fidei); and to illustrate Nicholas of Cusa's interest in mathematics and physics, the volume concludes with a dialogue on experiments in weighing. Hrne~a~T W. Sca~NEm~tt Claremont, California La cosmologie de Giordano Bruno. By Paul-Henri Michel. (Paris: Editions Hermann, 1962. Pp. 341.) Malgr~ les excellents travaux d~j~ publi~s (ceux d'Emile Namer, d'Augusto Guzzo et d'autres ~minents sp~cialistes bruniens), Giordano Bruno demeure une figure historique la lois tr~s c~l~bre et bien myst~rieuse au demeurant. L'exceUent ouvrage de Paul-Henri Michel rendra ainsi les plus grands services aux historiens de la pens~e qui se penchent avec curiosit~ sur la d~concertante p~iode de transition qui s~pare les philosophes de la Renaissance de l'av~nement en Europe d'attitudes proprement modernes devant la r~alit~ ext~rieure et l'homme. S'appuyant sans cesse sur les textes originaux de Bruno lui-mdme, pourvu d'un index complet, le bel ouvrage du Pr. Michel ne d~cevru passes lecteurs ~xudits. Comme il se dolt, rauteur commence par faire le point sur l'homme Bruno, s'attachant faire la distinction qui s'impose entre l'histoire et la l~gende--car la k~gende s'est empar ~e de ce philosophe, consid~r~ volontiers comme un athfie materialiste total ayant voulu d~truire la religion catholique, attitude louse ou vilipendfie selon clue Bruno sera vu comme un h~r~tique pervers ou, au contraire, comme un glorieux martyr de la "librepens ~" rationaliste.

Mais la majeure paxtie du volume est consacr~e ~ un expos~ m~thodique du syst~me du monde, telle clue l'~tude minutieuse de tousles textes accessibles permet de le structurer. En dix chapitres, l'auteur passe minutieusement--mais toujours d'une mani~re remarquablement logique et claire--les grandes articulations autour desquelles tourne toute la cosmologie brunienne: Le monde comme objet de connaissance, Cosmogonic, Ens mobile, LAme du Monde, La mati~re et l'univers infini, Le systkme solaire, Les mondes innombrables, L'univers vivant, Temps et dternit~.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:378 HISTORY OF PHILOSOPHY these churches to deal reasonably with frontier conditions and popular prejudices is common knowledge, but it is often forgotten that their founder and guide during the critical days of growth was also an exponent of the late Scottish Enlightenment. To make this careful analysis of Campbell's philosophy, as an extraordinary specimen of empirical method, is a welcome achievement by an experienced empiricist. The volume also (...) contains a Foreword by President Perry E. Gresham of Bethany College, and a comprehensive bibliography of Campbell's writings compiled by Claude E. Spencer. HERBERT W. SCHNEIDER Claremont, Cali]ornia Hegel's First American Followers, The Ohio Hegelians: J. B. Stallo, Peter Kau]mann, Moncure Conway, August WiUich. By Loyd D. Easton. (Athens, Ohio: Ohio University Press, 1966. Pp. lx + 353. $7.00.) This expansion of the theme outlined in Professor Easton's article of 1962 gives us fulllength accounts of the careers and ideas of four picturesque characters of the Ohio River Valley during the 19th century. The four had little in common except Hegel, and even him they did not really share, for they interpreted him differently and used him for different interests. The author is somewhat generous in calling them "Hegelians" and "followers" of Hegel, for like practically all those Americans who have been influenced by Hegel, they followed him at a safe distance and not very long. But this diversity makes Easton's account all the more fascinating. He portrays not only four characters but also the culture of Cincinati and its environment. J. B. Stallo is better known among American historians and philosophers than the other three, and deservedly so, for he was more philosophical. But he gains in stature here, noteworthy not only for his philosophy of nature but also as a prominent citizen, judge of a Superior Court, and political leader of a large German community. Stallo had two very different careers: the early Catholic student and teacher of Oken's philosophy of nature, mixed liberally with Schelling's similar system and with Hegel's Encyclopedia and his Phenomenology. Emerson was probably right in getting out of Stallo's General Principles an idea of "nature's rhythmic unfolding" rather than an idea of historical dialectic. Then came the later Stallo (after 1855), a convert from Catholicism and transcendentalism to empiricism, and a devoted follower of Ernst Mach. It is this later Stallo, author in 1881 of The Concepts and Theories oJ Modern Physics, who is better known, and who used the term "relativity" to indicate that physics deals not with things-in-themselves but with the data given to observers. Peter Kaufmann is an excellent representative of those pietists who, when they came to the open spaces and free manners of America, made serious attempts to give their religious "perfectionism" a practical social embodiment in utopian, communal economies. He became a teacher in the Rappite "Community of Equality and Social Harmony" and after a few years founded his own "Society of Germans at Teutonia." The members of this society agreed to devote their communal surplus to the education of orphans, the conversion of Indians, the spreading of the Gospel to "the four corners of the earth", and publishing a weekly Herald o] Better Times. After four years of this Society he moved northward to Canton, Ohio, where he settled down comfortably as a publisher and promoter of public education. His major publication, The Temple oJ Truth, incorporated some ideas on dialectic taken from Hegel. He continued his contacts with many utopian communities and urged his fellow citizens to help in making the United States of America "a saviour nation of the rest of mankind." Moncure Conway, a native of Virginia and graduate of Dickinson College, became an itinerant Methodist minister. But in 1853 the Harvard Divinity School made a Unitarian of him and an enthusiast for the higher criticism of Strauss and the transcendentalism of Hegel. In 1858 his wife introduced him to her home town, Cincinnati, and there he became BOOK REVIEWS 379 the minister of a very influential and liberal congregation. In 1860 he began publication in Cincinnati of The Dial, successor to the New England transcendentalist journal, and used its... (shrink)

A model for the trapping of animals with a circular pitfall is formulated. The model's assumptions are: The animals move independently according to the same Brownian motions. The boundary of the pitfall acts as an absorbing or elastic barrier. Initially a fixed number of animals is independently homogeneously distributed over a finite study area, or the initial positions follow a homogeneous planar Poisson process. The model depends on three free parameters: the motility of the animals, their reaction to the pitfall, (...) the initial density.It appears that the catches in disjoint time intervals are multinomially or independently Poisson distributed. The parameters of these distributions are obtained by solving certain partial differential equations. (shrink)
