It is common to distinguish between “holist” and “reductionist” views of brain function, where the former envisions the brain as functioning as an indivisible unit and the latter as a collection of distinct units that serve different functions. Opposing reductionism, a number of researchers have pointed out that cortical network architecture does not respect functional boundaries, and the neuroanatomist V. Braitenberg proposed to understand the cerebral cortex as a “great mixing machine” of neuronal activity from sensory inputs, motor commands, and (...) intrinsically generated processes. In this paper, we offer a contextualization of Braitenberg’s point, and we review evidence for the interactions of neuronal activity from multiple sensory inputs and intrinsic neuronal processes in the cerebral cortex. We focus on new insights from studies on audiovisual interactions and on the influence of respiration on brain functions, which do not seem to align well with “reductionist” views of areal functional boundaries. Instead, they indicate that functional boundaries are fuzzy and context dependent. In addition, we discuss the relevance of the influence of sensory, proprioceptive, and interoceptive signals on cortical activity for understanding brain-body interactions, highlight some of the consequences of these new insights for debates on embodied cognition, and offer some suggestions for future studies.

Respiratory rhythms sustain biological life, governing the homeostatic exchange of oxygen and carbon dioxide. Until recently, however, the influence of breathing on the brain has largely been overlooked. Yet new evidence demonstrates that the act of breathing exerts a substantive, rhythmic influence on perception, emotion, and cognition, largely through the direct modulation of neural oscillations. Here, we synthesize these findings to motivate a new predictive coding model of respiratory brain coupling, in which breathing rhythmically modulates both local and global neural (...) gain, to optimize cognitive and affective processing. Our model further explains how respiratory rhythms interact with the topology of the functional connectome, and we highlight key implications for the computational psychiatry of disordered respiratory and interoceptive inference.

Background: Community-based education (CBE) involves educating the head (cognitive), heart (affective), and the hand (practical) by utilizing tools that enable us to broaden and interrogate our value systems. This article reports on the use of virtue ethics (VE) theory for understanding the principles that create, maintain and sustain a socially accountable community placement programme for undergraduate medical students. Our research questions driving this secondary analysis were; what are the goods which are internal to the successful practice of CBE in medicine, (...) and what are the virtues that are likely to promote and sustain them? -/- Methods: We conducted a secondary theoretically informed thematic analysis of the primary data based on MacIntyre’s virtue ethics theory as the conceptual framework. -/- Results: Virtue ethics is an ethical approach that emphasizes the role of character and virtue in shaping moral behavior; when individuals engage in practices (such as CBE), goods internal to those practices (such as a collaborative attitude) strengthen the practices themselves, but also augment those individuals’ virtues, and that of their community (such as empathy). We identified several goods that are internal to the practice of CBE and accompanying virtues as important for the development, implementation and sustainability of a socially accountable community placement programme. A service-oriented mind-set, a deep understanding of community needs, a transformed mind, and a collaborative approach emerged as goods internal to the practice of a socially accountable CBE. The virtues needed to sustain the identified internal goods included empathy and compassion, connectedness, accountability, engagement [sustained relationship], cooperation, perseverance, and willingness to be an agent of change. -/- Conclusion: This study found that MacIntyre’s virtue ethics theory provided a useful theoretical lens for understanding the principles that create, maintain and sustain CBE practice.

Methodological critique of the sociological theory "spontaneous cooperation" to explain the revolution in Germany in 1989. This approach represented the german sociologists Dieter Opp and Detlef Pollack. The author reconstructs the two statements. Opp's approach is logically inconsistent. This approach is also unfit for scientific prediction, but Opp says the possibility of prediction is a necessary criterion for a scientific theory. Pollack's systemtheoretical approach ignores the really existing organized resistance of the subversive groups in Leipzig, for example the "Working (...) group for human rights" or the "Working group for Justice". Miracle or surprise chance are scientifically anacceptable models to explain a revolution. Both economically and politically offered the capitalist welfare state more for the workers than the socialism. So people noticed socialism as a system with more work for less prosperity and without civil rights, as a system of "exploitation by inefficiency" (Elsenhans). The author describes the revolution as a result of very effective collaboration between people, who willing to take risks and wanted to emigrate from the GDR to West, and the subversive groups, that could organize the revolutionary resistance. - This is a possible interpretation of the revolution from the interaction of transition-theory and voice-and-exit-theory (Hirschman).

Der akademischen Philosophie wird manchmal nachgesagt, sie suche Antworten auf Fragen, die außer Philosophen niemanden umtreiben. In diesem Band sind »zwölf philosophische Antworten« auf Fragen versammelt, die sich jeder irgendwann einmal stellt und über die professionelle Philosophen lediglich etwas schärfer und gründlicher nachdenken. Die Autoren dieses Bandes greifen pointiert, allgemeinverständlich und mit philosophischem Vertiefungsanspruch aktuelle Kontroversen auf. Sie erheben dabei den Anspruch, philosophisch argumentativ sowohl dem Zeitgeistrelativismus als auch der Dominanz empirischer Wissenschaften entgegenzutreten. Es ist keineswegs „alles bloß Ansichtssache“; denn (...) Toleranz ist nicht einfach nur achselzuckendes Wegschauen. Um zu einer klugen und begründeten Orientierung zu kommen, bedarf es auch nicht der einseitigen Zuflucht zu heute populären Antwortinstanzen wie der Religion, der Neurobiologie oder der Ökonomie. In der Tradition der philosophischen Aufklärung ist weiterhin auf den nachdenkenden Menschen zu setzen, der in der Philosophie vertiefende Anregungen erhält, um sich zu aktuellen Kontroversen ein begründetetes Urteil zu bilden. Über das Handwerk des Philosophen – Meinen, Glauben und Wissen – Rechte und Pflichten, Werte und Normen – Fairness als Prinzip – Zur Verteidigung der Freiheit als Dilemma – Zum Streit über das Lebewesen Mensch – Das Geist-Körper-Problem und die Hirnforschung – Das Schuldprinzip und die Willensfreiheit – Die Wissenschaft zwischen Natur und Kultur – Grenzen des wirtschaftlichen Denkens – Das Wahrheitsproblem in der Mediengesellschaft – Religion im Streit der Meinungen Mit Beiträgen von Simone Dietz, Heiner Hastedt, Detlef Horster, Peter Janich, Geert Keil, Corinna Mieth, Herbert Schnädelbach und Anke Thyen.

How compatible is a medical training with a future role in public office? Potentially very compatible and advantageous, particularly with regard to public policy issues, argues Dr Michael L Riordan.

Essay by Dr. Michael L. Riordan, the founder of Gilead Sciences, on the comparative utility of a medical versus legal education as preparation for public office.

This paper investigates the historical origin and ancestors of typicality, which is now a central concept in Boltzmannian Statistical Mechanics and Bohmian Mechanics. Although Ludwig Boltzmann did not use the word typicality, its main idea, namely, that something happens almost always or is valid for almost all cases, plays a crucial role for his explanation of how thermodynamic systems approach equilibrium. At the beginning of the 20th century, the focus on almost always or almost everywhere was fruitful for developing measure (...) theory and probability theory. It was apparently Hugh Everett III who first mentioned typicality in physics in 1957 while searching for a justification of the Born rule in his interpretation of quantum mechanics. The historically closest concept before these developments is moral certainty, which was invented by the medieval French theologian Jean Gerson, and it became a standard concept at least until the Age of Enlightenment, when Jakob Bernoulli proved the Law of Large numbers.
