35 The ventral intraparietal area (VIP) of the macaque monkey is thought to be 36 involved in judging heading direction based on optic flow. We recorded neuronal 37 discharges in VIP while monkeys were performing a two-alternative, forced-choice 38 heading discrimination task to relate quantitatively the activity of VIP neurons to 39 monkeys’ perceptual choices. Most VIP neurons were responsive...

Accurate perception of self-motion through cluttered environments involves a coordinated set of sensorimotor processes that encode and compare information from visual, vestibular, proprioceptive, motor-corollary, and cognitive inputs. Our goal was to investigate the visual and vestibular cues to the direction of linear self-motion (heading direction). In the vestibular experiment, blindfolded p...

The problem of exponential stabilization for nonholonomic mobile robot with dependent stochastic disturbance of heading angle is considered in this paper. An integrator backstepping controller based on state-scaling method is designed such that the state of the closed-loop system, starting from a nonzero initial heading angle, is regulated to the origin with exponential rate in almost surely se...

Although considerable progress has been made in understanding how adults perceive their direction of self-motion, or heading, from optic flow, little is known about how these perceptual processes develop in infants. In 3 experiments, the authors explored how well 3- to 6-month-old infants could discriminate between optic flow patterns that simulated changes in heading direction. The results sug...

To study the contribution of vision to the perception of ego-motion, one often dissociates the retinal flow from the corresponding extra-retinal information on eye, head and body movement. This puts the observer in a conflict concerning the experienced ego-motion. When the retinal flow of a translating and rotating eye is shown to a stationary eye, observes often perceive ego-motion on a curved...

Heading date is an important agronomic trait in rice (Oryza sativa L.); it determines the geographical and seasonal adaptability of the crop. Single segment substitution lines (SSSLs) have become the preferred experimental materials in mapping functional genetic variations as the particular chromosome segments from donor genotypes can be evaluated for their impact on the phenotype in a recurren...

The problem under study is a synthesis of position and heading control system for low frequency model of surface vessel described by 3 DOF mathematical model. The recursive vectorial backstepping control design was used to keep fixed position and heading in presence of wave disturbances. The controller has been simulated on computer model of scaled supply vessel. It has been assumed that the ac...

Psychophysical experiments have shown that human heading judgments can be biased by the presence of moving objects. Here we present a theoretical argument that motion differences can account for the direction of bias seen in humans. We further examine the responses of a computer simulation of a model for computing heading that uses motion-opponent operators similar to cells in the primate middl...

IntroductIon After fevered media coverage of a possible link between football (soccer) heading and long-term damage to the brain, 2016 saw the Professional Footballers’ Association call for a review of the game to decide whether to follow the lead of the United States Soccer and ban heading for younger players. Given these concerns, and the fact the relevant Rules of Football were conceived ove...
