An fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
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...
متن کاملVisual acuity with brief stimuli.
INTRODUCTION ALTHOUGH the visual acuity of the eye has been often investigated, it has not yet been examined very fully in conditions of limited exposure time. The only known previous investigations in this field are those of Graham and Cook (1937), and Niven and Brown (1944), apart from a similar investigation on the somewhat analogous problem of intensity discrimination at short exposure time...
متن کاملVisual Scanning of Dynamic Affective Stimuli in Autism Spectrum Disorders
The accurate integration of audio-visual emotion cues is critical for social interactions and requires efficient processing of facial cues. Gaze behavior of typically developing (TD) individuals and individuals with autism spectrum disorders (ASD) was measured via eyetracking during the perception of dynamic audio-visual emotion (DAVE) stimuli. This study provides information about the regions ...
متن کاملVisual Foraging With Fingers and Eye Gaze
A popular model of the function of selective visual attention involves search where a single target is to be found among distractors. For many scenarios, a more realistic model involves search for multiple targets of various types, since natural tasks typically do not involve a single target. Here we present results from a novel multiple-target foraging paradigm. We compare finger foraging wher...
متن کاملEncoding of dynamic visual stimuli by primate area MT neurons
Neural stimulus selectivity is thought to be optimized for the representation of real-world stimuli. Neural coding properties, therefore, may adapt to different environments. Here, we address the question if tuning curves depend on the statistics of visual stimuli. This is done by studying the directional tuning of macaque area MT neurons exposed to dynamic motion stimuli of two different direc...
