Priming visual face-processing mechanisms: electrophysiological evidence.
Accumulated evidence from electrophysiology and neuroimaging suggests that face perception involves extrastriate visual mechanisms specialized in processing physiognomic features and building a perceptual representation that is categorically distinct and can be identified by face-recognition units. In the present experiment, we recorded event-related brain potentials in order to explore possibl...
متن کاملProcessing visual words with numbers: electrophysiological evidence for semantic activation.
Perea, Duñabeitia, and Carreiras (Journal of Experimental Psychology: Human Perception and Performance 34:237-241, 2008) found that LEET stimuli, formed by a mixture of digits and letters (e.g., T4BL3 instead of TABLE), produced priming effects similar to those for regular words. This finding led them to conclude that LEET stimuli automatically activate lexical information. In the present study...
متن کاملSlow intrinsic rhythm in the koniocellular visual pathway.
Slow rhythmic changes in nerve-cell activity are characteristic of unconscious brain states and also may contribute to waking brain function by coordinating activity between cortical and subcortical structures. Here we show that slow rhythms are exhibited by the koniocellular (K) pathway, one of three visual pathways beginning in the eye and projecting through the lateral geniculate visual rela...
متن کاملAn 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 کاملNo Visual Mismatch Negativity (MMN) for Simultaneously Presented Audiovisual Stimuli: Evidence from Human Brain Processing
The present study employed simultaneous audiovisual stimuli in the oddball paradigm to re-examine the effects of attention on audio, visual and audiovisual perception. The study was designed to investigate whether task-related processing of audio and visual features was independent or task-related processing in one modality might influence the processing of the other. Electroencephalogram (EEG)...
