TLDR
Direct electrophysiological evidence for serial cortical processing in somesthesia is similar to that found earlier for vision and, taken together with recent anatomical evidence, suggests that there is a common cortical plan for the processing of sensory information in the various sensory modalities.Abstract:
Removal of the representation of a specific body part in the postcentral cortex of the macaque resulted in the somatic deactivation of the corresponding body part in the second somatosensory area. In contrast, removal of the entire second somatosensory area had no grossly detectable effect on the somatic responsivity of neurons in the postcentral cortex. This direct electrophysiological evidence for serial cortical processing in somesthesia is similar to that found earlier for vision and, taken together with recent anatomical evidence, suggests that there is a common cortical plan for the processing of sensory information in the various sensory modalities.read more

Plasticity of sensory and motor maps in adult mammals.
TL;DR: This rev iew addresses questions about the capacity of sensory and motor maps in the brains of adul t mammals to change as a resul t of alterations in the effectiveness of inputs, the availability of effectors, and direct damage.

Flutter discrimination: neural codes, perception, memory and decision making.
Ranulfo Romo,Emilio Salinas +1 more
TL;DR: In this paper, the primary somatosensory cortex drives higher cortical areas where past and current sensory information are combined, such that a comparison of the two evolves into a behavioural decision.

Somatosensory processes subserving perception and action
TL;DR: It is suggested that, analogously to the organisation of the visual system, somatosensory processing for the guidance of action can be dissociated from the processing that leads to perception and memory.

Convergence of Visual and Tactile Shape Processing in the Human Lateral Occipital Complex
TL;DR: It is suggested that LOtv, the cortical region LOtv for the lateral occipital tactile-visual region, is involved in recovering the geometrical shape of objects.
Journal ArticleDOI
Functional imaging of human crossmodal identification and object recognition.
TL;DR: These studies show that visual, tactile, and auditory information about objects can activate cortical association areas that were once believed to be modality-specific, and propose a general mechanism for crossmodal object recognition.

Laminar origins and terminations of cortical connections of the occipital lobe in the rhesus monkey.
TL;DR: Different cortical projection systems are characterized by specific laminar distributions of efferent terminations as well as of their neurons of origin.

Cortical connections of the somatosensory fields of the lateral sulcus of macaques: evidence for a corticolimbic pathway for touch.
TL;DR: The ipsilateral corticocortical connections of the somatosensory fields of the lateral sulcus of macaques were examined with both anterograde and retrograde axonal transport methods to identify field of interest prior to the injection of the tracer substance.

Organization of the amygdalopetal projections from modality-specific cortical association areas in the monkey
TL;DR: All of the telencephalic sensory systems of the rhesus monkey are examined for efferents to the amygdala and immediately surrounding structures, using primarily the Fink‐Heimer technique to understand how sensory stimuli influence emotional processes.

Representations of the body surface in postcentral parietal cortex of Macaca fascicularis
TL;DR: The somatotopic organization of the postcentral parietal cortex of the Old World monkey, Macaca fascicularis, was determined with multi‐unit microelectrode recordings and it is suggested that the representation in Area 3b is homologous to “SmI” (or “SI”) in non‐primates.

Somatotopographic organization in the second somatosensory area of M. fascicularis.
C. J. Robinson,Harold Burton +1 more
TL;DR: The second somatosensory area of awake, untrained cynomolgus monkeys was surveyed with recordings from nearly 1,000 single neurons and found that neighboring sequences of neurons in SII do not form a precise topologic map of the body that is comparable to the somatotopic maps observed in areas 3b and 1.
