Randomized Controlled Trial Comparative Study Clinical Trial
CAP variables and arousals as sleep electroencephalogram markers for primary insomnia.
Polysomnographic (PSG) measures consistently reflect poor sleep quality and effective treatment in insomniac patients. ⋯ PSG investigation extended to CAP variables and EEG arousals can be an important procedure for the diagnosis of primary insomnia and evaluation of treatment efficacy.

Comparative Study
The prognostic value of evoked responses from primary somatosensory and auditory cortex in comatose patients.
To evaluate somatosensory and auditory primary cortices using somatosensory evoked potentials (SEPs) and middle latency auditory evoked potentials (MLAEPs) in the prognosis of return to consciousness in comatose patients. ⋯ The prognostic value of SEPs and MLAEPs in comatose patients depends on the cause of coma. Measurement of response amplitudes is informative. Abolition of cortical SEPs and/or cortical MLAEPs precludes post-anoxic comatose patients from returning to consciousness (100% specificity). In any case, the presence of short latency cortical somatosensory or auditory components is not a guarantee for return to consciousness. Late components should then be recorded.

To investigate the effect of conditioning painful stimulation on the early somatosensory magnetic fields (SEF) of test stimulation, in order to clarify the location of the gating effect of pain on tactile response. ⋯ The finding suggested that the touch gate might lie in the thalamus or SI.

Randomized Controlled Trial Comparative Study Clinical Trial
Effects of TMJ anesthesia and jaw gape on jaw-stretch reflexes in humans.
To study the roles of afferent sensory inputs in the temporomandibular joint (TMJ) and of muscle length in the modulation of the jaw-stretch reflex in humans. ⋯ Blocking the afferent sensory input (including the mechanoreceptors) from the TMJ seems to have no influence on the sensitivity of the human jaw-stretch reflex. Instead, muscle spindles are the most likely receptors to be responsible for the reflex modulation that was observed in the present study.
