Alpha tACS on Parieto-Occipital Cortex Mitigates Motion Sickness Based on Multiple Physiological Observation
Summary
Transcranial alternating current stimulation (tACS) targeting alpha oscillations in the brain
Area of Science:
- Neuroscience
- Neuromodulation
- Sensory Integration
Background:
- Motion sickness (MS) affects about one-third of the population, linked to sensory integration dysfunction.
- Transcranial alternating current stimulation (tACS) modulates brain activity via neural oscillations.
- The application of tACS for motion sickness treatment remains unexplored.
Purpose of the Study:
- Investigate brain oscillation changes during motion sickness stimuli.
- Explore the potential of tACS to alleviate motion sickness symptoms.
Main Methods:
- 19 subjects exposed to Coriolis stimuli to induce motion sickness.
- Random assignment to tACS or sham stimulation groups.
- EEG, ECG, and GSR recorded; alpha power changes analyzed.
Main Results:
- Significant decrease in parieto-occipital alpha power observed in subjects with motion sickness symptoms.
- tACS group showed improved behavioral performance and normalized alpha oscillations compared to sham.
- Alpha oscillations in the parieto-occipital region are critical for sensory integration.
Conclusions:
- Alpha oscillations in the parieto-occipital lobe are crucial for sensory integration.
- Alpha tACS applied to the parieto-occipital region shows potential for mitigating motion sickness.

01:15Equilibrium and Balance
4.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:28Major Somatic Sensory Pathways
939
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

01:29The Vestibular System
39.5K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:22Pathophysiology of Vomiting
382
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...
