The response of the human visual system to moving spatially-periodic patterns.

چکیده
Thework is concerned with the two critical frequencies that are associated withthe visual observation of a moving, spatially periodic pattern. Data are given for thedependence of these frequencies upon the input parameters of the stimulus (e.g. spatialperiod, and area). On the basis of these data, it is concluded that the system has features incommon with the known optomotor response of certain insects. In particular, the systemdemonstrates the property of phase blindness and also a phenomenon probably related tothe ‘pattern reversal’ effect found in the case of the insect. It was further found that the de Langec.f.f. filters are insensitive to spatial variations in the phases of the input stimuli. A network,capable of detailed analysis, is suggested that functionally describes the behaviour of thesystem. Rbutn~-On etudie les deux frequences critiques associees a I’observation visuelle d’unrbeau periodique spatial en mouvement. On determine ces frequences en fonction desparambtres d’entree du stimulus (ptriode spatiale et aire). On en deduit que ce systeme a destraits en commun avec la rtponse optomotrice connue chez certains insectes. En particulier,ce systeme posstde la propriete de &cite; & la phase et aussi un phenomene en relationprobable avec le renversement du r&eau; trouve chez l’insecte. On trouve en outre que lestiltres de frequence critique de de Lange sont insensibles aux variations spatiales dans lesphases des stimuli d’entree. On suggere un n&au; de conducteun capable dune analysedetaillte et qui dtcrit fonctionnellement le comportement de ce systeme. Zusammenfassung-In dieser Arbeit handelt es sich um die zwei kritischen Frequenzen. welcheim Zusammenhang mit der Betrachtung eines sich bewegenden, raum-period&hen; Mustersstehen. Es werden Ergebniase fur die Abhlingigkeit dieser Frequenzen von den Eingangs-reizparametem (z.B. Raumperiode und Fliichengri%se) geliefert. Auf Grund dieser Ergebnissewird geschlossen, dass das System Kennzeichen hat, welche von den Optomotorreaktionengewisser Insekte her bekannt sind. Das System veranschaulicht insbesondere die Eigenschaftder Phasenblindheit und such ein anderes Phgnomen, welches mijglicherweise mit derMusterverkehrung, die bei Insekten beobachtet werden kann, verwandt ist. Es wurde suchgefunden, dass die de Langeschen Fusionsfrequenzen fir rlumliche Anderungen der Reiz-phasen unempfindlich sind. Ein Netzwerk, welches im Einzelnen untersucht werden kann,wird fur die funktionelle Beschreibung des Betragens dieses Systems vorgeschlagen. &3ioMeBpa6oTe Il3~~Cb~Kp~Tu~~~eSaCTOTbl,CBI13aBHbIeCo3pHT~HbLMria6nsoAemieM AmiXcytUerocs nepHoAsi%cKoro npocTpaHcTBeriHor0 narrepaa.

متن کاملHopf bifurcation analysis of a diffusive predator-prey model with Monod-Haldane response
In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...
متن کاملChaotic Response and Bifurcation Analysis of a Timoshenko Beam with Backlash Support Subjected to Moving Masses
A simply supported Timoshenko beam with an intermediate backlash is considered. The beam equations of motion are obtained based on the Timoshenko beam theory by including the dynamic effect of a moving mass travelling along the vibrating path. The equations of motion are discretized by using the assumed modes technique and solved using the Runge–Kutta method. The analysis methods employed in...

Introduction: Encoding models are used to predict human brain activity in response to sensory stimuli. The purpose of these models is to explain how sensory information represent in the brain. Convolutional neural networks trained by images are capable of encoding magnetic resonance imaging data of humans viewing natural images. Considering the hemodynamic response function, these networks are ...

ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
