SA1 and RA afferent responses to static and vibrating gratings.
SA1 and RA afferent fibers differ both in their ability to convey information about the fine spatial structure of tactile stimuli and in their frequency sensitivity profiles. In the present study, we investigated the extent to which the spatial resolution of the signal conveyed by SA1 and RA fibers depends on the temporal properties of the stimulus. To that end, we recorded the responses evoked...
متن کاملSA1 and RA receptive fields, response variability, and population responses mapped with a probe array.
Twenty-four slowly adapting type 1 (SA1) and 26 rapidly adapting (RA) cutaneous mechanoreceptive afferents in the rhesus monkey were studied with an array of independently controlled, punctate probes that covered an entire fingerpad. Each afferent had a receptive field (RF) on a single fingerpad and was studied at 73 skin sites (50 mm2). The entire array was lowered to 1.6 mm below the point of...
متن کاملTemporal factors in tactile spatial acuity: evidence for RA interference in fine spatial processing.
We investigated the extent to which subjects' ability to perceive the fine spatial structure of a stimulus depends on its temporal properties (namely the frequency at which it vibrates). Subjects were presented with static or vibrating gratings that varied in spatial period (1-8 mm) and vibratory frequency (5-80 Hz) and judged the orientation of the gratings, presented either parallel or perpen...
متن کاملSurround suppression in the responses of primate SA1 and RA mechanoreceptive afferents mapped with a probe array.
Twenty-four slowly adapting type 1 (SA1) and 26 rapidly adapting (RA) cutaneous mechanoreceptive afferents in the rhesus monkey were studied with an array of independently controlled, punctate probes that covered an entire fingerpad. Each afferent had a receptive field (RF) on a single fingerpad and was studied at 73 skin sites (50 mm2). The entire array was lowered to 1.6 to 3.0 mm below the p...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
