Tactile sensation and discrimination are critical functions of the primate hand, yet the integration of signals from the many sensory neurons in the hand is not well understood. Here, the authors provided evidence for widespread sensory input integration in the brain of the owl monkey, Aotus trivirgatus. While small minimal receptive fields in monkey primary somatosensory cortex area 3b are imp...

In order to interact with the multisensory world that surrounds us, we must integrate various sources of sensory information (vision, hearing, touch...). A fundamental question is thus how the brain integrates the separate elements of an object defined by several sensory components to form a unified percept. The superior colliculus was the main model for studying multisensory integration. At th...

Animal nervous systems resolve sensory conflict for the control of movement. For example, the glass knifefish, Eigenmannia virescens, relies on visual and electrosensory feedback as it swims to maintain position within a moving refuge. To study how signals from these two parallel sensory streams are used in refuge tracking, we constructed a novel augmented reality apparatus that enables the ind...

This is the second of two papers addressing the occupational behavior and sensory integration approaches to occupational therapy for children. In the previous paper, basic concepts from these two approaches were discussed as presenting different, yet complementary, perspectives. The use of play was identified as central to occupational therapy practice from either perspective. Concepts from bot...

Occupational therapy, along with other health and rehabilitation professions, is experiencing an increased emphasis on measurement of intervention outcomes. The results of outcomes research are being used to develop practice guidelines, set standards for reimbursement, and justify health care policy. The outcome assessments used by therapists reflect our belief systems and the assumptions about...

Findings in animal models demonstrate that activity within hierarchically early sensory cortical regions can be modulated by cross-sensory inputs through resetting of the phase of ongoing intrinsic neural oscillations. Here, subdural recordings evaluated whether phase resetting by auditory inputs would impact multisensory integration processes in human visual cortex. Results clearly showed audi...

We present a novel methodology for building highly integrated multimodal systems. Our approach is motivated by current cognitive and behavioral theories of sensory perception in animals and humans. We argue that perceptual integration in multimodal systems needs to happen at the lowest levels of the individual perceptual processes. Rather than treating each modality as a separately processed, i...

This systematic review aims to verify whether tools designed assess Ayres Sensory Integration constructs take into account the basic principles of current early childhood intervention approaches, namely family-centered approach, child and family routines, natural contexts. was based on a standard protocol constructed according Preferred Reporting Items for Systematic Reviews (PRISMA) statement ...

Introduction: Children from under-resourced environments often lack opportunities to engage in sensory experiences that support developmental abilities and scholastic performance. “Back Urth” playgrounds were designed address the needs of foundation phase learners communities. A 12-week sensory-motor program, based on Ayres Sensory Integration ® (ASI) principles, was developed, educators traine...
