Anaesthetic depth also modulates receptive fields and sizes of representations in the somatosensory cortex of rats (Erchova et al., 2002), and affects modulation of receptive field sizes by nucleus interpolaris (but not principalis) in the ventroposterior medial subdivision of the ventroposterior nucleus (Friedberg et al., 1999).
Consistent with previous investigations of motor representations in the cortex, there was considerable variation in the site of peak activity during the knee task in people with and without knee OA [ 17, 33, 34].
Although it is established that the face representation in the cortex can widen after traumatic loss of the hand, our results indicate that hand loses cortical activity after a relatively small loss of facial movements.
It is probable that in sensory areas of the brain, the skin is served by a large number of neurons, the muscles with fewer, and the viscera with least, the visceral representation in the cortex being very small compared with that of the somatic tissues.
Although brain imaging has demonstrated object-category specific representations in the occipitotemporal cortex, the crucial question of how the brain acquires this knowledge has remained unresolved.
Inhibition of motor representations in the motor cortex during voluntary movement selection could actively interfere with tremor-related firing in the cerebello-thalamo-cortical circuit, causing an immediate arrest of the tremor.
The articulatory-feature-specific effects found in our "virtual lesion" study suggest that it is possible to suppress excitability of motor representations in the M1 cortex selectively using sub-threshold low-frequency rTMS (Möttönen & Watkins, 2009).
The amplitude of anterior shift in the motor cortex representation of the knee in knee OA was related to the quality of performance of the task (more anterior representation was related to poorer performance) and was specific to the knee; organisation of the ankle or hand representations in the motor cortex did not differ when an identical task was performed at these segments.
(2007) proposed that the nature of the task (attention) modifies the stimulus representations in the auditory cortex.
