Neuropsychological Approaches to Visually-Induced Vection: an Overview and Evaluation of Neuroimaging and Neurophysiological Studies
2020
Abstract Moving visual stimuli can elicit the sensation of self-motion in stationary observers, a phenomenon commonly referred to as vection. Despite the long history of vection research, the neuro-cognitive processes underlying vection have only recently gained increasing attention. Various neuropsychological techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have been used to investigate the temporal and spatial characteristics of the neuro-cognitive processing during vection in healthy participants. These neuropsychological studies allow for the identification of different neuro-cognitive correlates of vection, which (a) will help to unravel …
Suppression of extinction with TMS in humans: from healthy controls to patients.
2006
We review a series of studies exemplifying some applications of single-pulse and paired-transcranial magnetic stimulation (TMS) in the study of spatial attention and of its deficits. We will focus primarily on sensory extinction, the failure to consciously perceive a contralesional sensory stimulus only during bilateral stimulation of homologous surfaces. TMS studies in healthy controls show that it is possible either to interfere or modulate the excitability of the parietal cortex during sensory (i.e. tactile and visual) attentional tasks, thus reproducing a condition of virtual extinction. TMS studies in patients with unilateral (mainly right) brain damage show that the modulation of the …
Contribution of the Temporal Dominance of Sensations (TDS) method to the sensory description of subtle differences in partially dealcoholized red win…
2009
Abstract In this study, effect of partial alcohol reduction on the sensory modification of red wines was investigated. A Merlot and a Syrah wine were partially dealcoholized using reverse osmosis technique to span a range of three different alcohol contents (14–10%) by grape variety. Preliminary triangle tests indicated the existence of very slight differences between the dealcoholized wines of the study. Therefore, adapted descriptive methodologies had to be used. In a first step, wines were described with a comparative sensory profile by 16 trained panellists on 15 sensory attributes. Then, the same panellists profiled the wines with the TDS technique, which consists in identifying and ra…

Psychomotor disadaptation syndrome
2020
Psychomotor disadaptation syndrome (PDS) was first described by the Geriatrics School of Dijon (France), three decades ago, under the name «psychomotor regression syndrome». Over time, the original clinical features remained unchanged. However, progress has been made in its pathophysiology understanding and care, hence the new name, PDS, appeared in the 1990s. The PDS is also called sub-cortico-frontal dysfunction syndrome since the 2000s. It corresponds to a decompensation of posture, gait and psychomotor automatisms, related to an alteration of the postural and motor programming, which is a consequence of sub-cortico-frontal lesions. The clinical features of PDS associate backward disequi…
Sensible et communication: du cognitif au symbolique
2016
International audience; Les sensations prennent sens sur le fond identitaire du rapport à soi et aux autres. Du symbolique au sensoriel, l’inscription sociale et culturelle des situations de communication (normes, rites, codes, processus culturalisés) contribue à préfigurer un monde de sensations et d’émotions à partir d’images et de valeurs préexistantes.Chacun se représente aisément la vie sensible, sa réalité, son imaginaire, mais tout se complique dès qu’il faut définir en propre le sensible. Terme difficilement traduisible qui compose avec le sensoriel, le discours, les formes, comme avec les mots, les moments ou les émotions.Le sensible marque le passage de l’incantation à l’incarnati…

"Over the last hill": Wilfred Owen's "Spring Offensive"
2021
Being the poet’s last completed piece, “Spring Offensive” makes France Wilfred Owen’s last poetic landscape. The article explores the ways in which “Spring Offensive” continuously crosses and blurs the borders between the French landscape and the poet’s English heritage; it also emphasizes the sensuousness of the landscape and of the war experience, so that the bodies of the soldiers and nature fuse and interact. “Spring Offensive” thus comes to reflect Owen’s search for balance, a search of which the French landscape becomes the natural yet symbolic representation.
