Data from: Pupillometry reveals perceptual differences that are tightly linked to autistic traits in typical adults

Marco Turi, David Charles Burr & Paola Binda
The pupil is primarily regulated by prevailing light levels, but is also modulated by perceptual and attentional factors. We measured pupil-size in typical adult humans viewing a bistable-rotating cylinder, constructed so the luminance of the front surface changes with perceived direction of rotation. In some participants, pupil diameter oscillated in phase with the ambiguous perception, more dilated when the black surface was in front. Importantly, the magnitude of oscillation predicts autistic traits of participants, assessed...

Data from: Response to short-term deprivation of the human adult visual cortex measured with 7T BOLD

Paola Binda, Jan W. Kurzawski, Claudia Lunghi, Laura Biagi, Michela Tosetti & Maria Concetta Morrone
Sensory deprivation during the post-natal "critical period" leads to structural reorganization of the developing visual cortex. In adulthood, the visual cortex retains some flexibility and adapts to sensory deprivation. Here we show that short-term (2h) monocular deprivation in adult humans boosts the BOLD response to the deprived eye, changing ocular dominance of V1 vertices, consistent with homeostatic plasticity. The boost is strongest in V1, present in V2, V3 &V4 but absent in V3a and hMT+....

Data from: Rhythmic motor behavior influences perception of visual time

Alice Tomassini, Tiziana Vercillo, Francesco Torricelli & Maria Concetta Morrone
Temporal processing is fundamental for an accurate synchronization between motor behavior and sensory processing. Here we investigate how motor timing during rhythmic tapping influences perception of visual time. Participants listen to a sequence of four auditory tones played at 1 Hz and continue the sequence (without auditory stimulation) by tapping four times with their finger. During finger tapping, they are presented with an empty visual interval and are asked to judge its length compared to...

Data from: Assessing reliance on vector navigation in the long-distance oceanic migrations of green sea turtles

Vector navigation, i.e. maintaining a constant heading for a given amount of time, is hypothesized to provide a viable basis for the navigational feats of a number of long-distance animal migrants. Since animals following this strategy are subject to drift by wind or by ocean current, performing long migrations relying on vector navigation is particularly challenging. We tested whether vector navigation could be involved in the migrations of green turtles (Chelonia mydas) that migrate between...

Data from: Below-ground processes control the success of an invasive seaweed

1. Whilst the successful establishment and spread of invasive species can be determined by above ground processes, results are often equivocal. Emergent research, mostly from terrestrial ecosystems, demonstrates that below-ground processes (nutrient cycling, chemical properties) under microbial control can mediate interactions between native and invasive plants. Because microbes can control similar sediment properties in marine ecosystem that influence plant fitness, we argue that below-ground properties should also exert strong control interactions between native and invasive...

Data from: The functional role of serial dependence

Guido Marco Cicchini, Kyriaki Mikellidou & David C. Burr
The world tends to be stable from moment to moment, leading to strong serial correlations in natural scenes. As similar stimuli usually require similar behavioral responses, it is highly likely that the brain has developed strategies to leverage these regularities. A good deal of recent psychophysical evidence is beginning to show that the brain is sensitive to serial correlations, causing strong drifts in observer responses towards previously seen stimuli. However, it is still not clear...
