Significance Neural oscillations are hypothesized to play an important role in modulating perceptual processing accordance with top-down goals. For instance, the amplitude, phase, and spatial distribution of alpha-band change attention. Given recent links between peak frequency alpha temporal resolution perception, we investigated whether modulation occurs when task demands emphasize integration or segregation visual input over time. We found that occipital–temporal cortex decreased during,...
When processing dynamic input, the brain balances opposing needs of temporal integration and sensitivity to change. We hypothesized that visual system might resolve this challenge by aligning windows onset newly arriving sensory samples. In a series experiments, human participants observed same sequence two displays separated brief blank delay when performing either an or segregation task. First, using magneto-encephalography (MEG), we found shift in stimulus-evoked time courses 150-ms...
Recent behavioral, neuroimaging, and neurophysiological studies have renewed the idea that information processing within different temporal windows is linked to phase and/or frequency of ongoing oscillations, predominantly in theta/alpha band (∼4–7 8–12 Hz, respectively). However, being correlational nature, this evidence might reflect a nonfunctional byproduct rather than having causal role. A more direct link can be shown with methods manipulate oscillatory activity. Here, we used...
Across cultures and throughout recorded history, humans have produced visual art. This raises the question of why people report such an emotional response to artworks find some works more beautiful or compelling than others. In current study we investigated interplay between art expertise, preference judgments. Sixty participants (40 novices, 20 experts) rated a set 150 abstract portraits during two occasions: in laboratory setting museum. Before commencing their second session, half novices...
Significance To reduce the complexity of our sensory environment, perceptual system discretizes information in different ways. In time domain, this is evident when stimuli that are presented very close sometimes faithfully perceived as entities, whereas they integrated into a single event at other times. Using multivariate decoding electroencephalography data, we show integration and segregation over scales (a few tens vs. hundreds milliseconds) do not rely on sampling rhythm; instead,...
Abstract Throughout recorded history, and across cultures, humans have made visual art. In recent years, the neural bases of creativity, including artistic become a topic interest. this study we investigated creative process with both professional artists group control participants. We tested idea that creativity (planning an artwork) would influence functional connectivity between regions involved in default mode network (DMN), implicated divergent thinking generating novel ideas, executive...
Developmental Dyslexia (DD) is a neurobiological condition affecting the ability to read fluently and/or accurately. Analyzing resting-state electroencephalographic (EEG) activity in DD may provide deeper characterization of underlying pathophysiology and possible biomarkers. So far, studies investigating provided limited evidence did not consider aperiodic component power spectrum. In present study, adults with (n = 26) without 31) underwent reading skills assessment EEG investigate...
Although our visual experience of the world is rich and full detail, short-term memory (VSTM) can retain only about four objects at a time. Long-term (LTM) for pictures lasts longer but may rely on abstract gist, raising question how it possible to remember details natural scenes. We studied accumulation persistence shown 1–20 s. Performance in answering questions increased linearly as function total time that scene was viewed. Similar gains were found items central marginal interest. No...
Most artworks are explicitly created to evoke a strong emotional response. During the centuries there were several art movements which employed different techniques achieve expressions conveyed by artworks. Yet people always consistently able read messages even from most abstract paintings. Can machine learn what makes an artwork emotional? In this work, we consider set of 500 paintings Museum Modern and Contemporary Art Trento Rovereto (MART), where each painting was scored as carrying...
Dynamic vision requires both stability of the current perceptual representation and sensitivity to accumulation sensory evidence over time. Here we study electrophysiological signatures this intricate balance between temporal segregation integration in vision. Within a forward masking paradigm with short long stimulus onset asynchronies (SOA), manipulated overlap visual persistence two successive transients. Human observers enumerated items presented second target display as measure...
Many common tasks require us to individuate in parallel two or more objects out of a complex scene. Although the mechanisms underlying our abilities count number items, remember visual properties and make saccadic eye movements towards targets have been studied separately, each these selection individual shows capacity limit. Here we show that factor—salience—determines limit various tasks. We manipulated bottom-up salience (visual contrast) top-down (task relevance) enumeration memory As...
Human cognition is characterized by severe capacity limits: we can accurately track, enumerate, or hold in mind only a small number of items at time. It remains debated whether limitations across tasks are determined common system. Here measure brain activation adult subjects performing either visual short-term memory (vSTM) task consisting holding precise information about the orientation and position variable items, an enumeration assessing those sets. We show that task-specific limits...
The phase and frequency of neural oscillations in the alpha band (8-12 Hz) have been recently proposed as key parameters for temporal resolution visual perception. Here, we tested possible causal links between these oscillatory features integration/segregation. individual (IAF) peak obtained from resting-state electroencephalography was used to set sensory (audio-visual) entrainment lower (IAF - 2 upper + alpha. Entrainment at IAF ± Hz administered prestimulus interval align a faster or...
Abstract A basic question in vision research regards where people look complex scenes and how this influences their performance various tasks. Previous studies with static images have demonstrated a close link between what they remember. Here, we examined the pattern of eye movements when participants watched neutral emotional clips from Hollywood-style movies. Participants answered multiple-choice memory questions concerning visual auditory scene details immediately upon viewing 1-min-long...
Abstract The brain organizes the continuous flow of sensory input by parsing it into discrete events. In case two flashes separated a brief ISI, for example, perception may be single flash or distinct flashes, depending on ISI but also speed processing. A number studies have reported evidence that participants with higher EEG peak alpha frequency are able to detect presence short intervals, whereas those slower report only one flash. Other not found this correlation. We investigated...
