The still-radii illusion, the figure-of-eight illusion, the band-of-heightened-intensity illusion and the dark-blurred-concentric-circles illusion have remained, until now, isolated relatively illexplained phenomena. A single algorithmic model is proposed which explains these four visual illusions. In fact, this model predicts phenomena produced by motion of any gray-shaded patterns relative to the eyes (termed 'motion-blur illusions'). Results of a computer simulation of the model aredoi:10.1068/p260847 pmid:9509138 fatcat:mrtxxgjy3rf3pfai24s3yhpsgm

Higher densities of tree microhabitats in unmanaged forests may explain biodiversity differences with managed forests. To better understand the determinants of this potential biodiversity indicator, we studied the influence of tree characteristics on a set of tree microhabitats (e.g. cavities, cracks, bark features) on 75 plots in managed and unmanaged French forests. We hypothesized that the number of different microhabitat types per tree and the occurrence of a given microhabitat type on adoi:10.1016/j.biocon.2010.09.030 fatcat:2ock3ifz5bfh3cxv3lattv24pq

We show that unmanaged forests contained more trees likely to host microhabitats (i.e. large trees, snags) at the stand level. However, at the tree level, forest management did not influence microhabitats; only tree characteristics did: large trees and snags contained more microhabitats. The number and occurrence of microhabitats also varied with tree species: oaks and beech generally hosted more microhabitats, but occurrence of certain types of microhabitats was higher on fir and spruce. We conclude that, even though microhabitats are not equally distributed between managed and unmanaged forests, two trees with similar characteristics in similar site conditions have the same number and probability of occurrence of microhabitats, whatever the management type. In order to preserve biodiversity, foresters could reproduce unmanaged forest features in managed forests through the conservation of specific tree types (e.g. veteran trees, snags). Tree microhabitats could also be more often targeted in sustainable forest management monitoring.
Visual object recognition seems to occur almost instantaneously. However, not only does it require hundreds of milliseconds of processing, but our eyes also typically fixate the object for hundreds of milliseconds. Consequently, information reaching our eyes at different moments is processed in the brain together. Moreover, information received at different moments during fixation is likely to be processed differently, notably because different features might be selectively attended atdoi:10.1101/566042 fatcat:7w36asqfrfa5lokm5udghekrzi

Using a random sampling of information across time and reverse correlation with EEG activity, we decomposed the brain response to faces and uncovered for the first time the processing time course of specific information received on the retina at specific moments. We observed that processing at several electrodes and latencies was different depending on the moment at which information was received. Some of these variations were caused by a disruption occurring 160-200 ms after the face onset, suggesting a role of the N170 ERP component in gating information processing; others hinted at temporal compression and integration mechanisms. Importantly, the observed differences were not explained by simple adaptation or repetition priming, they were modulated by the task, and they were correlated with differences in behavior. These results suggest that top-down visual routines of information extraction are applied to the continuous visual input, even within a single eye fixation.

It is well known that expectations influence how we perceive the world. Yet the neural mechanisms underlying this process remain unclear. Studies have focused so far on artificial contingencies between simple neutral cues and events. Real-world expectations are however often generated from complex associations between potentially affective contexts and objects learned over a lifetime. In this study, we used fMRI to investigate how object processing is influenced by neutral and affectivedoi:10.1101/408542 fatcat:2vohfqsoebf7vjpvtvb2tmxnai

First, we show that the precuneus and the inferotemporal cortex are more active during object recognition when expectations have been elicited a priori, irrespectively of their validity or their affective intensity. This result supports previous hypotheses according to which these brain areas integrate contextual expectations with object sensory information. Early visual areas, on the contrary, are more active during object recognition when no prior expectation has been elicited by a context. Finally, we show that BOLD activity is enhanced in early visual areas when objects are less expected, but only when contexts are neutral; the reverse effect is observed when contexts are affective. This result supports a recent proposal that affect modulates predictions in the brain. Together, our results help elucidate the neural mechanisms of real-world expectations.
