Bruxism and autonomic activity

Masseter EMG activity during sleep and sleep bruxism.

The masseter muscle is involved in the complex and coordinated oromotor behaviors such as mastication during wakefulness. The masseter electromyographic (EMG) activity decreases but does not disappear completely during sleep: the EMG activity is generally of low level and inhomogeneous for the duration, amplitude and intervals. The decreased excitability of the masseter motoneurons can be deter...

Bruxism and nocturnal groaning.

Sleep bruxism (SB) is a sleep-related movement disorder, characterized by tooth grinding and/or clenching. The causes of SB range from psychosocial factors to an excessive sleep arousal response. Some studies showed that SB episodes during sleep are under the influences of transient activity of the brainstem arousal. Nocturnal groaning (NG) is a parasomnia characterized by an expiratory monoton...

Links between autonomic activity and implicit learning.

The somatic marker hypothesis posits that autonomic activity occurring in response to specific stimuli aids in implicit learning, the learning of information without explicit awareness of what has been learned. This study investigated whether respiratory sinus arrhythmia (RSA), a measure of autonomic nervous system activity, predicted changes in implicit learning. The interaction of resting RSA...
