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

Translation is at the centre of many cognitive domains such as pedagogy, linguistic, pragmatic, neurosciences, and social cognition. This multi-domain aspect is reflected in the current models of translation. Recently, cognitive neurosciences have unraveled some brain mechanisms in the bilingualism domain, and it is quite logical to transfer such knowledge to the field of translation as well as...

Exploration of the neural correlates of ticklish laughter by functional magnetic resonance imaging

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

In: Cerebral Cortex, 2013, vol. 23, no. 6, p. 1280-1289

The burst of laughter that is evoked by tickling is a primitive form of vocalization. It evolves during an early phase of postnatal life and appears to be independent of higher cortical circuits. Clinicopathological observations have led to suspicions that the hypothalamus is directly involved in the production of laughter. In this functional magnetic resonance imaging investigation, healthy...

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...
