Insular cortex activity and the evocation of laughter

Wattendorf, Elise ; Westermann, Birgit ; Lotze, Martin ; Fiedler, Klaus ; Celio, Marco R.

In: Journal of Comparative Neurology, 2015, p. -

The insular cortex is fundamentally involved in the processing of interoceptive information. It has been postulated that the integrative monitoring of the bodily responses to environmental stimuli is crucial for the recognition and experience of emotions. Because emotional arousal is known to be closely coupled to functions of the anterior insula, we suspected laughter to be associated primarily...

Aging causes a reorganization of cortical and spinal control of posture

Papegaaij, Selma ; Taube, Wolfgang ; Baudry, Stéphane ; Otten, Egbert ; Hortobágyi, Tibor

In: Frontiers in Aging Neuroscience, 2014, vol. 6, p. 28

Classical studies in animal preparations suggest a strong role for spinal control of posture. In humans it is now established that the cerebral cortex contributes to postural control of unperturbed and perturbed standing. The age-related degeneration and accompanying functional changes in the brain, reported so far mainly in conjunction with simple manual motor tasks, may also affect the...

Neurocognitive aspects of translation

Annoni, Jean-Marie ; Lee-Jahnke, Hannelore ; Sturm, Annegret

In: Meta, 2012, vol. 57, no. 1, p. 96-107

La traduction est au centre de différents domaines cognitifs, telles la pédagogie, la linguistique, la pragmatique, les neurosciences et la cognition sociale. Les modèles actuels de la traduction reflètent ce caractère interdisciplinaire. Récemment, les neurosciences ont découvert des mécanismes cérébraux en relation avec le bilinguisme, et il serait logique de transférer ce savoir à...

Dissociated lateralization of transient and sustained blood oxygen level-dependent signal components in human primary auditory cortex

Lehmann, Christoph ; Herdener, Marcus ; Schneider, Peter ; Federspiel, Andrea ; Bach, Dominik R. ; Esposito, Fabrizio ; di Salle, Francesco ; Scheffler, Klaus ; Kretz, Robert ; Dierks, Thomas ; Seifritz, Erich

In: NeuroImage, 2007, vol. 34, no. 4, p. 1637-1642

Among other auditory operations, the analysis of different sound levels received at both ears is fundamental for the localization of a sound source. These so-called interaural level differences, in animals, are coded by excitatory–inhibitory neurons yielding asymmetric hemispheric activity patterns with acoustic stimuli having maximal interaural level differences. In human auditory cortex, the...
