Inner speech has been shown to vary in form along several dimensions. Along condensation, condensed inner speech forms have been described, that are supposed to be deprived of acoustic, phonological and even syntactic qualities. Expanded forms, on the other extreme, display articulatory and auditory properties. Along dialogality, inner speech can be monologal, when we engage in internal soliloquy, or dialogal, when we recall past conversations or imagine future dialogues involving our own voice as well as that of others addressing us. (...) Along intentionality, it can be intentional (when we deliberately rehearse material in short-term memory) or it can arise unintentionally (during mind wandering). We introduce the ConDialInt model, a neurocognitive predictive control model of inner speech that accounts for its varieties along these three dimensions. ConDialInt spells out the condensation dimension by including inhibitory control at the conceptualization, formulation or articulatory planning stage. It accounts for dialogality, by assuming internal model adaptations and by speculating on neural processes underlying perspective switching. It explains the differences between intentional and spontaneous varieties in terms of monitoring. We present an fMRI study in which we probed varieties of inner speech along dialogality and intentionality, to examine the validity of the neuroanatomical correlates posited in ConDialInt. Condensation was also informally tackled. Our data support the hypothesis that expanded inner speech recruits speech production processes down to articulatory planning, resulting in a predicted signal, the inner voice, with auditory qualities. Along dialogality, covertly using an avatar’s voice resulted in the activation of right hemisphere homologues of the regions involved in internal own-voice soliloquy and in cerebellar deactivation, consistent with internal model adaptation. Switching from first-person to third-person perspective resulted in activations in precuneus and parietal lobules. Along intentionality, compared with intentional inner speech, mind wandering with inner speech episodes was associated with greater bilateral inferior frontal activation and decreased activation in left temporal regions. This is consistent with the reported subjective evanescence and presumably reflects condensation processes. Our results provide neuroanatomical evidence compatible with predictive control and in favor of the assumptions made in the ConDialInt model. (shrink)

Despite the occasional upsurge of climate change scepticism amongst conservative politicians and journalists, there is a near-consensus amongst scientists that current levels of atmospheric greenhouse gas are sufficient to alter global weather patterns to possibly disastrous effect. Like the hole in the ozone layer as described by Bruno Latour, global warming is a ‘hybrid’ natural-social-discursive phenomenon. And science fiction seems to occupy a critical location within this nature/culture nexus. This paper takes as its subject matter what Daniel Bloom dubs ‘cli-fi’. (...) It seeks to describe how a genre defined in relation to science finds itself obliged to produce fictional responses to problems actually thrown up by contemporary scientific research. It argues against the view that ‘catastrophic’ SF is best understood as a variant of the kind of ‘apocalyptic’ fiction inspired by the Christian Book of Revelation, or Apokalypsis, on the grounds that this tends to downplay the historical novelty of SF as a genre defined primarily in relation to modern science and technology. And it examines the narrative strategies pursued in both print and audio-visual SF texts that deal with anthropogenic climate change. (shrink)

Preoperative mapping of language and declarative memory functions in temporal lobe epilepsy patients is essential since they frequently encounter deterioration of these functions and show variable degrees of cerebral reorganization. Due to growing evidence on language and declarative memory interdependence at a neural and neuropsychological level, we propose the GE2REC protocol for interactive language-and-memory network mapping. GE2REC consists of three inter-related tasks, sentence generation with implicit encoding and two recollection memory tasks: recognition and recall. This protocol has previously been validated (...) in healthy participants, and in this study, we showed that it also maps the LMN in the left TLE. Compared to healthy controls, left TLE showed widespread inter- and intra-hemispheric reorganization of the LMN through reduced activity of regions engaged in the integration and the coordination of this meta-network. We also illustrated how this protocol could be implemented in clinical practice individually by presenting two case studies of LTLE patients who underwent efficient surgery and became seizure-free but showed different cognitive outcomes. This protocol can be advantageous for clinical practice because it is short and easy to perform; allows brain mapping of essential cognitive functions, even at an individual level; engages language-and-memory interaction allowing to evaluate the integrative processes within the LMN; provides a more comprehensive assessment by including both verbal and visual modalities, as well as various language and memory processes. Based on the available postsurgical data, we presented preliminary results obtained with this protocol in LTLE patients that could potentially inform the clinical practice. This implies the necessity to further validate the potential of GE2REC for neurosurgical planning, along with two directions, guiding resection and describing LMN neuroplasticity at an individual level.

In an illusion, if what has been said in the earlier part of this section is right, the essential thing is the presence to the mind of some false proposition, which may be affirmed or denied according as we are or are not deceived. But what precisely is this false proposition in each case? And, a second question, on what grounds do we entertain it?

The following discussion arises out of reflection upon a number of related topics. One of these is the problem of perception, and in particular of perceptual illusion. Another is the use which has been made, e.g. by Bradley, of the distinction between appearance and reality as a guiding principle of metaphysical inquiry. But the immediate occasion of the present inquiry is the attempt to discover what Kant in particular has to say upon these and similar problems. It is for this (...) reason that I have given the paper its title, and not because I wish to pose as an expert in Kantian scholarship. What contribution I can make to Kantian studies is only that of the outsider whose questions may perhaps suggest to the experts lines of inquiry which their very familiarity with Kant's ways of expressing himself may have led them to overlook. But the aim of the paper is not so much to discover what Kant meant as to formulate a particular view which may have been Kant's in such a way that we can judge whether it is true or not. The decision on that point, however, falls outside the scope of the present discussion. (shrink)

La musique a exercé depuis les temps les plus reculés une telle fascination sur l’esprit humain que l’homme n’a eu de cesse de créer des instruments nouveaux, de les perfectionner, de travailler sa voix pour lui donner la plus parfaite expression, de rechercher de nouvelles harmonies, de se laisser guider par son inspiration afin de concevoir les plus belles oeuvres. Mais d’où vient cette inspiration qui permit à certains êtres de léguer à l’humanité des chefs-d'oeuvre qui, plusieurs siècles après leur (...) naissance, continuent à élever notre âme? Et quel est, ou quel devrait être, le rôle véritable de la musique? C’est ce que nous découvrirons en lisant ces lignes. Les articles de cette oeuvre collégiale, conçue dans le cadre de l’Université Rose-Croix Internationale, apportent un éclairage original et vécu sur le rôle de la musique dans le domaine spécifique de la spiritualité. Ils explorent l’apport de musiciens de génie et se penchent également sur le comportement de l’auditeur, qui ne peut être purement passif s’il veut bénéficier pleinement des influences les plus subtiles de la musique. Par ailleurs, ces articles analysent l’importance de l’interprétation, qui est essentielle, tant pour la transmission que pour la réception de l’oeuvre musicale. (shrink)
