چکیده

Elegant sensory structures in the inner ear have evolved to measure head motion. These vestibular receptors consist of highly conserved semicircular canals and otolith organs. Unlike other senses, vestibular information in the central nervous system becomes immediately multisensory and multimodal. There is no overt, readily recognizable conscious sensation from these organs, yet vestibular signals contribute to a surprising range of brain functions, from the most automatic reflexes to spatial perception and motor coordination. Critical to these diverse, multimodal functions are multiple computationally intriguing levels of processing. For example, the need for multisensory integration necessitates vestibular representations in multiple reference frames. Proprioceptive-vestibular interactions, coupled with corollary discharge of a motor plan, allow the brain to distinguish actively generated from passive head movements. Finally, nonlinear interactions between otolith and canal signals allow the vestibular system to function as an inertial sensor and contribute critically to both navigation and spatial orientation.

Fuzzy particle swarm optimization with nearest-better neighborhood for multimodal optimization

In the last decades, many efforts have been made to solve multimodal optimization problems using Particle Swarm Optimization (PSO). To produce good results, these PSO algorithms need to specify some niching parameters to define the local neighborhood. In this paper, our motivation is to propose the novel neighborhood structures that remove undesirable niching parameters without sacrificing perf...

Review Paper: Introduction of Pediatric Balance Therapy in Children with Vestibular Dysfunction: Review of Indications, Mechanisms, and Key Exercises

The vestibular system is important for the development of normal movement reactions, motion tolerance, and motor control for postural alignment, balance, and vision. A vestibular system that is damaged by disease or injury in childhood can have a major impact on a child’s development. In addition, the emergence of vestibular lesions may also lead to cognitive deficits,...

مقایسه نتایج آزمون ویدئویی ایمپالس سر در افراد مبتلا به تومورهای سیستم دهلیزی محیطی و مرکزی

Background and purpose: Vestibular Schwannoma (VS) is a lesion in peripheral vestibular system that leads to reduction of Vestibulo Ocular Reflex (VOR) gain and incidence of corrective saccades. Researches showed that the result of Video Head Impulse Test (VHIT) is positive in peripheral vestibular system disorders and negative in central vestibular system disorders. The aim of this study was t...

A Decision Support System for Urban Journey Planning in Multimodal Public Transit Network

The goal of this paper is to develop a Decision Support System (DSS) as a journey planner in complex and large multimodal urban network called Rahyar. Rahyar attempts to identify the most desirable itinerary among all feasible alternatives. The desirability of an itinerary is measured by a disutility function, which is defined as a weighted sum of some criteria. The weight...
