Prenatal nicotine exposure evokes alterations of cell structure in hippocampus and
somatosensory cortex.
The sway-referenced platform tilts with the patient's sway, thereby altering
somatosensory input.
The brains of Old World macaque monkeys clearly have a large number of auditory, visual, and
somatosensory areas.
This test, previously described in detail elsewhere (2,35,39), measures the contribution and interaction of the visual,
somatosensory and vestibular systems during postural responses to a set of six changing sensory conditions, by measures of postural sway and response strategy.
The analysis of AP sway characteristics in this study has provided insight concerning the role of visual and
somatosensory inputs in balance control.
Maintenance of balance usually involves the integration of visual, vestibular,
somatosensory and proprioceptive sensory inputs.
The team suspected that when people try to tickle themselves, the cerebellum ruins the fun by sending urgent messages to the
somatosensory cortex warning that a sensation is on its way.
Furthermore, if the basal ganglia in part perform a comparator function between efferent motor plan and proprioreceptive feedback, the high gain of the
somatosensory response seen with passive movements may turn off motor activity prematurely in the belief that the active movement had already reached target parameters of amplitude and velocity.
The percentage of women, depression severity, level of general psychopathology and distress, and somatic symptom reporting (SCL-90), as well as the tendency to
somatosensory amplification and three forms of somatic symptom attributions, were significantly higher in alexithymic patients than in non-alexithymic patients.
Thus,
somatosensory information was degraded, forcing the brain to reweight mainly on the visual and vestibular systems.
Characteristics of synaptic connections between rodent primary
somatosensory and motor cortices.
By its nature, TMSR changes the way the brain processes motor control and
somatosensory input; however the detailed brain mechanisms have never been investigated before and the success of TMSR prostheses will depend on our ability to understand the ways the brain re-maps these pathways.
