Synergistic augmentation of rhythmic myogenic contractions of human stomach by arginine vasopressin and adrenaline: Implications for the induction of nausea

British Journal of Pharmacology, Volume 179, Issue 24, Page 5305-5322, December 2022., 2022
Background and Purpose Nausea is associated with the hormonal secretion of vasopressin and adrenaline, although their actions in inducing nausea is poorly understood. Here, we have investigated their actions on human stomach muscle. Experimental Approach Muscle strips were suspended in tissue baths and neuronal‐/non‐neuronally‐mediated contractions ...

Central correlates of placebo effects in nausea differ between men and women

Brain and Behavior, Volume 12, Issue 8, August 2022., 2022
In the present study, EEG characteristics during anticipated and acute nausea were investigated in an experimental nausea paradigm in 45 men and 45 women. Compared with no treatment, the placebo intervention reduced the expected intensity of nausea inall participants, which was associated with increased ACC and PFC activity.

Visual and vestibular reweighting after cyber- and space-sickness. [PDF]

Exp Physiol
Abstract Sensory conflicts are widely recognized as the primary drivers of motion sickness (MS), though the underlying integrative processes remain poorly understood. This study investigated sensory reweighting following exposure to two different sensory conflict paradigms. Visual and vestibular reflexes were assessed before and after sensory conflict.

Electroencephalographic response to transient adaptation of vestibular perception

The Journal of Physiology, Volume 600, Issue 15, Page 3517-3535, 1 August 2022., 2022
Abstract figure legend Three‐panelled figure showing an overview of study methods and major findings. Left: side view graphic of rotating chair that was used to deliver asymmetric, whole‐body rotation around an Earth vertical axis. Below in blue is a sample stimulus profile of the asymmetric chair oscillations (not to scale).

Cauliflower mosaic virus protein P6‐TAV plays a major role in alteration of aphid vector feeding behaviour but not performance on infected Arabidopsis

Molecular Plant Pathology, Volume 22, Issue 8, Page 911-920, August 2021., 2021
The viral protein P6, a major determinant of symptoms in infected plants, affects aphid behaviour in a way that could be favourable for transmission of cauliflower mosaic virus. Abstract Emerging evidence suggests that viral infection modifies host plant traits that in turn alter behaviour and performance of vectors colonizing the plants in a way ...

Inhibition of vection by red [PDF]

Attention, Perception, & Psychophysics, 2010
We investigated the effects of colors on vection induction. Expanding optical flows during one's forward self-motion were simulated by moving dots. The dots and the background were painted in equiluminant red and green. Experiments 1 and 2 showed that vection was weaker when the background was red than when the background was green.

Identifying Objective EEG Based Markers of Linear Vection in Depth

Frontiers in Psychology, 2016
This proof-of-concept study investigated whether a time-frequency EEG approach could be used to examine vection (i.e., illusions of self-motion). In the main experiment, we compared the event-related spectral perturbation (ERSP) data of 10 observers ...

Spatiotemporal boundaries of linear vection [PDF]

Perception & Psychophysics, 1995
Thresholds for the perception of linear vection were measured. These thresholds allowed us to define the spatiotemporal contrast surface sensitivity and the spatiotemporal domain of the perception of rectilinear vection (a visually induced self-motion in a straight line).

Stronger vection in junior high school children than in adults.

Frontiers in Psychology, 2014
Previous studies have shown that even elementary school-aged children (7 and 11 years old) experience visually induced perception of illusory self-motion (vection) (Lepecq et al., 1995, Perception, 24, 435–449) and that children of a similar age (mean ...
