Kritiske Steps: Øyebevegelser skjermer må være riktig innstilt på motivet. For eksempel, øyebevegelser opptak målere fungerer innenfor et område og må tilpasses til emnet. Hvis motivet er øyebevegelser går utover området, vil systemet blir mettet. Ved metning, er øyets bevegelsessignalet ikke gyldig. Kalibrering er også kritisk i øyebevegelser opptak. Alle øyebevegelser skjermer måle et analogsignal som blir digitalisert og må omdannes til enheter som vanligvis brukes i øyebev...

Erratum: VisualEyes: A Modular Software System for Oculomotor Experimentation

visualeyes: a modular software system for oculomotor experimentation

Øyebevegelser studier har gitt et sterkt fundament som danner en forståelse av hvordan hjernen får visuell informasjon i både normal og dysfunksjonell hjerne. 1 Men utvikling av en plattform for å stimulere og lagre øyebevegelser kan kreve betydelig programmering, tid og kostnader. Mange systemer ikke tilby den fleksibiliteten til å programmere en rekke stimuli for en rekke eksperimentelle behov. Imidlertid har VisualEyes System en fleksibel arkitektur, slik at føreren kan velge hvilken som helst bakgrunn og forgrunn stimulans, program en eller to skjermer for tandem eller motstridende øyebevegelser og stimulere til venstre og høyre øye uavhengig. Dette systemet kan redusere programmerings utvikling tiden det tar å gjennomføre en oculomotor studien. Den VisualEyes System vil bli diskutert i tre deler: 1) oculomotor opptaksenhet å erverve øyebevegelser svar, 2) VisualEyes programvare skrevet i LabView, for å generere en rekke stimuliog lagre svar som tekstfiler og 3) offline dataanalyse. Øyebevegelser kan tas opp av flere typer instrumenter som: en limbus tracking system, en sclera søk spiral, eller et videobilde system. Typiske øyebevegelser stimuli som rykke-trinn, vergent ramper og vergent trinn med tilhørende svar vil bli vist. I denne videoen rapporten viser vi fleksibiliteten til et system for å lage en rekke visuelle stimuli og plate øyebevegelser som kan utnyttes av grunnleggende forskere og klinikere til å studere sunne samt kliniske populasjoner.

VisualEyes: A Modular Software System for Oculomotor Experimentation

Neural kontroll og kognitive prosesser kan studeres gjennom øyebevegelser. Den VisualEyes programvare gjør at føreren kan programmere stimuli på to dataskjermer uavhengig ved hjelp av en enkel, tilpasset skriptspråk. Systemet kan stimulere tandem øyebevegelser (rykninger og glatt jakten) eller motstridende øyebevegelser (konvergens) eller en kombinasjon.
