These examples open up new avenues that go beyond studying perception in restricted and artificial laboratory scenarios: some using video recordings from authentic lessons to others studying actual classrooms.
studies present examples of how to capture visual perception in the complexity of a classroom lesson. This distilling and interpreting happen to a large extent via visual perception, which is the core focus of the current Special Issue. It is thus crucial that both can distil the relevant information in this complex scenario and interpret it appropriately.

Additional findings indicate REM-locked cerebral vasodilation and suggest putative mechanisms for dream forgetting. These results are consistent with hierarchical predictive coding namely, permissive deactivation of DMN at the top of the hierarchy (leading to the widespread cortical activation at lower levels especially the primary visual cortex). Furthermore, our analysis revealed a modest temporally-precise REM-locked decrease-phasic deactivation-in key DMN nodes, in a subset of independent studies.
A reanalysis of these data revealed that the cortical areas exempt from widespread REM-locked brain activation were restricted to the DMN. We timed REMs during sleep from the video recordings and quantified the neural correlates of REMs-using functional MRI (fMRI)-in 24 independent studies of 11 healthy participants. The implicit anticorrelation between the DMN and task-positive network (TPN)-that persists in REM sleep-prompted us to focus on DMN responses to temporally-precise REM events. Default mode network (DMN) activity increases during rest and reduces during various tasks including visual perception. of virtual-world models, through multisensory integration in dreaming-as in awake states. This pattern suggests that REMs underwrite hierarchical processing of visual information in a time-locked manner, where REMs index the generation and scanning. System-specific brain responses-time-locked to rapid eye movements (REMs) in sleep-are characteristically widespread, with robust and clear activation in the primary visual cortex and other structures involved in multisensory integration. In the concluding section we discuss the methodological implications of these results and suggest the notion of regime of attention as a focus for future biosocial research on urban mental health. The analysis shows how these elements elicit physiological responses of arousal and expressed feelings of discomfort. We focus on three salient elements in our results: visual perception of moving bodies, spatial transitions and openness and enclosure of the built environment. Empirically, the paper is based on fieldwork in Basel, Switzerland, with nine participants recruited within the Basel Early Treatment Service (BEATS), and four controls. The second explores stress and emotional arousal in cities using ambulatory physiological measures. The first relates to the use of digital phenotyping in mental health research. cross-fertilize two recent strands of research.
It adopts a biosocial approach, using mixed methods combining ambulatory skin conductance monitoring, mobile interviews and contextual data, collected through GPS and video recordings.
