Within, but not between hands interactions in vibrotactile detection thresholds reflect somatosensory receptive field organization
Detection of a tactile stimulus on one finger is impaired when a concurrent stimulus (masker) is presented on an additional finger of the same or the opposite hand. This phenomenon is known to be finger-specific at the within-hand level. However, whether this specificity is also maintained at the between hand level is not known. In four experiments, we addressed this issue by combining a Bayesi...
متن کاملHands.
Hands are awesome. Hands are marvelous in every sense of the word, and are as important to us collectively and individually as are our intellects. Hands are the difference between thinking and doing. There may be other creatures in this world that have intelligence, but if they don’t have hands, they cannot act on that intelligence. They cannot make things and place things. Without hands, they ...
متن کاملAcquired prosopagnosia with spared within-class object recognition but impaired recognition of degraded basic-level objects.
We present a new case of acquired prosopagnosia resulting from extensive lesions predominantly in the right occipitotemporal cortex. Functional brain imaging revealed atypical activation of all core face areas in the right hemisphere, with reduced signal difference between faces and objects compared to controls. In contrast, Herschel's lateral occipital complex showed normal activation to objec...
متن کاملDirect coupling of haptic signals between hands.
Although motor actions can profoundly affect the perceptual interpretation of sensory inputs, it is not known whether the combination of sensory and movement signals occurs only for sensory surfaces undergoing movement or whether it is a more general phenomenon. In the haptic modality, the independent movement of multiple sensory surfaces poses a challenge to the nervous system when combining t...
