Altered sensory processing has been an important feature of the clinical descriptions of autism spectrum disorder (ASD). There is evidence that sensory dysregulation arises early in the progression of ASD and impacts social functioning. This paper reviews behavioral and neurobiological evidence that describes how sensory deficits across multiple modalities (vision, hearing, touch, olfaction, gu...

BACKGROUND Diagnosing cobalamin (Cbl) deficiency as a cause of polyneuropathy (PN) is problematic, as the frequency of both disorders increases with age, and serum Cbl levels can be difficult to interpret. OBJECTIVES To identify unique clinical or laboratory features among PN patients with Cbl deficiency and to examine the role of testing of serum metabolite levels in the identification of Cb...

The assessment of sensory perception, discrimination, integration, modulation, praxis, and other motor skills, such as posture, balance, and bilateral motor coordination, is necessary to identify the sensory and motor factors influencing the development of personal autonomy. The aim of this work is to study the assessment tools currently available for identifying different patterns of sensory p...

Introduction: Sensory Gating Inventory (SGI) measures behavioral aspects of Sensory Gating (SG). It is a filtering mechanism of brain that prevents irrelevant sensory inputs from entering into higher cortex information processing. It modifies sensitivity to sensory stimuli. Abnormal SG leads to overloading of information into cortex and brain dysfunction. Electrophysiological techniques cannot ...

OBJECTIVE. This retrospective study explored sensory processing characteristics in preschool-age children with autism spectrum disorders (ASD); the relationships between sensory processing and problem behavior, adaptive behavior, and cognitive function; and the differences in sensory processing between two subgroups (autism and pervasive developmental disorder-not otherwise specified). METHOD. ...

We conducted an experiment, similar to those in (Peterka 2002) but augmented to include information processing (IP) tasks, to explore this question. Data were fit to a postural control model (Peterka 2002; Peterka and Loughlin 2004). We explicitly added “attention” to the model and its influence on sensory integration via the sensory weight and time delay parameters of the model (Fig. 1). This ...

OBJECTIVE Research regarding sensory processing and adults with attention deficit hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) is limited. This study aimed to compare sensory processing patterns of groups of higher education students with ADHD or ASD and to explore the implications of these disorders for their college life. METHOD The Adolescent/Adult Sensory Profile was ad...

Neuromorphic Sensory Processing Using Analog Very Large-Scale Integration Circuits Neuromorphic circuits are analog circuits that implement models of biological systems for sensory processing. Because the neuromorphic circuits share the same physical constraints as their biological counterparts, they have similar organizational structures and use similar strategies for optimizing robustness to ...
