Dynamic touch.

A variety of recent experiments are reported, showing that in this kind of touching, which is closely connected with the states of muscles, the nervous system cleverly exploits the physics of rotations.

When action is not enough: Tool-use reveals tactile-dependent access to Body Schema

Armed With Information: Cognition and Consciousness and the Octopus Nervous System

On Proprioception in Action: Multimodality versus Deafferentation

Recent research on proprioception reveals that it relies on a systematically distorted model of bodily dimensions. This generates a puzzle about proprioception in action control: action requires

Somatosensory Loss Influences the Adoption of Self-Centered Versus Decentered Perspectives

The deafferented patients rely on strategies that are more prone to interindividual differences, which highlights the crucial role of somatosensory information in adopting self-centered spatial perspectives.

The importance of the sense of touch in virtual and real environments

Providing users with inadequate somesthetic feedback in virtual environments might impair their performance, just as major somesthetic loss does.

Timing of bimanual movements and deafferentation: implications for the role of sensory movement effects

The results of the present study support another hypothesis, namely that bimanual timing profits from the averaging of different central control signals that relate to each effector’s movements.

A Psychological Approach to Human Voluntary Movements , " and Response of the Author

F. Mechsner (2004) bases his argument for ihe primacy of perception on a simplitled interpretation of phase transition findings. The authors show that attention to the details of phase transition

The Effect of Chronic Deafferentation on Mental Imagery: A Case Study

The results suggest that kinaesthetic afferent signals from the body periphery play a crucial role in enabling and maintaining central sensorimotor representations and hence the ability to incorporate kinesthetic information into the imagery processes.

Does Proprioception Influence Human Spatial Cognition? A Study on Individuals With Massive Deafferentation

The main finding of this study is that proprioception can influence the time necessary to use spatial representations while other factors such as visuo-spatial abilities can influenceThe capacity to form accurate spatial representations.



Localization without content. A tactile analogue of 'blind sight'.

We examined the ability of a patient, who had a cerebral lesion involving the left posterior hemisphere, to identify and to localize stimuli applied to her "deafferented" right upper limb. We

The control of hand movements in a case of hemianaesthesia following a parietal lesion.

A 46-year-old patient with a lesion limited to the left retrorolandic area without involvement of the prerolandic motor strip was examined and the role of somatosensory cortex in conveying kinesthetic input to the motor areas and the importance of vision in substituting for kinaesthetic loss are discussed.

The perceptions of force and of movement in a man without large myelinated sensory afferents below the neck.

It is concluded that a crude sense of effort remains which may have a peripheral origin and differences in movement ability between this subject and others with similar if less pure sensory neuropathies are ascribed to rehabilitation.

Cognitive Versus Sensorimotor Encoding of Spatial Information

The study of spatially oriented behaviour has been dominated by the trenchant opposition between behaviourist and cognitivist theories, which stresses the need for both clarifying concepts and domains and attempting to translate them in neural terms.

Manual motor performance in a deafferented man.

It is shown that a man deafferented by a severe peripheral sensory neuropathy could produce a very wide range of preprogrammed finger movements with remarkable accuracy, involving complex muscle synergies of the hand and forearm muscles.

Motor control in humans with large-fiber sensory neuropathy.

Proprioceptive afferent inputs are important for accurate postural maintenance and the fine control of movement in patients with a large-fiber sensory neuropathy associated with impaired position, vibration and cutaneous sensation.

Postural changes accompanying voluntary movements. Normal and pathological aspects.

The possibility is examined that a "repertoire" of postural adjustments exists and the possible sites of the repertoire are discussed as well as the level at which the parallel or "sequential" control of posture and movement might be organized.

Rapid elbow flexion in the absence of proprioceptive and cutaneous feedback.

It is concluded that the central nervous system can generate a sequence of commands to accelerate and decelerate a limb in the absence of peripheral feedback, however, information from the moving limb is required to adjust the magnitude and time of onset of deceleration.
