The use of the masseteric nerve as donor nerve represents a single-stage alternative to the criterion standard two-stage procedure of cross-facial nerve grafting and free muscle transfer in facial paralysis. We provide a detailed description to safely perform this technique with a gracilis muscle transfer and discuss indications and limitations.

This video demonstrates an in vivo imaging-based assay to determine proteostasis decline due to aging. The assay uses Caenorhabditis elegans expressing polyglutamine YFP-fusion protein in body wall muscles to measure the age-associated aggregation of polyglutamine and induction of proteotoxicity, leading to paralysis.

Inducing Paralysis in a Mouse Model via Transfer of Aquaporin-4-Specific Th17 Cells

This video demonstrates the procedure of inducing paralysis by transferring activated Th17 cells targeting aquaporin-4 into a mouse model. In the central nervous system, the activated Th17 cells interact with aquaporin-4-expressing astrocytes, triggering an immune response that leads to tail and limb paralysis in the mouse.

FAQs
The inhibition normally limits the influence of dream-related neural activity on skeletal muscles. If that restraint is incomplete, motor signals can reach the muscles instead of remaining functionally blocked. This provides a physiological explanation for why actions associated with dream content may appear as physical movements, making the mechanism important for interpreting sleep behavior.
The brainstem initiates inhibitory signaling during REM sleep, while pathways in the spinal cord transmit that inhibition toward motor neurons. Reduced motor-neuron activity helps keep skeletal muscles from carrying out movement. Muscle paralysis absence can therefore arise when this brainstem-to-spinal inhibitory system does not sufficiently suppress motor output during REM-related brain activity.
Typical REM sleep combines dream-related activity with strong skeletal-muscle inhibition, creating a separation between what the brain is experiencing and what the body performs. When that inhibition is absent or incomplete, the separation becomes less effective. Movements can then accompany a state that ordinarily restricts physical action, offering a useful contrast for studying REM physiology.
Dream enactment becomes understandable when signals associated with dream-related activity reach skeletal muscles during REM sleep. Rather than being fully contained by inhibitory pathways, those signals can produce observable movement. This connection links subjective dream activity with physical behavior and gives psychologists a mechanism for examining how sleep-related mental events may influence motor expression.
It provides a way to investigate REM sleep behavior through the relationship between neural inhibition, dream-related activity, and movement. Studying the failure of temporary motor suppression can clarify why some behaviors occur during REM sleep and can help researchers connect brain-state mechanisms with observable actions relevant to psychological sleep research.
The phenomenon highlights that conscious or dream-like experience and physical movement are normally regulated through partly separable systems. REM sleep can support dream-related activity while inhibitory circuits restrict motor output. When that restriction fails, the resulting movements expose how the brain usually keeps internal experience from directly producing skeletal-muscle action.
