dissociating temporal and spatial integration windows the case of vernier fusion

-4 -3 -2 -1 0 1 2 3 4 Arcmin Single/Fusion Motion Double / Segregation The visual system constructs a percept of the world across multiple spatial and temporal scales. We investigated this using Vernier Fusion, a phenomenon in which the features of two Vernier stimuli presented in close spatio-temporal proximity are fused into a single percept. With increasing spatial offset, perception changes dramatically from a single percept into apparent motion and later, at larger offsets, into two separately perceived stimuli (Scharnowski et al., 2007). Previous studies exclusively used binary choice to investigate this phenomenon

reduced erp amplitudes for animal stimuli in the absence of conscious awareness

and easily extracted; (2) Animal stimuli deviate from non-animal stimuli around 150ms after stimulus onset (ERPs, Thorpe, Fize et al. 1996) Question: (1) Does this remarkable capability function in the absence of awareness? (2) Are there any differences between animal and non-animal in the suppressed condition? (Are animals special?) Introduction Paradigm: CFS (continuous flash suppression) break-through (experiment 1) and plain CFS paradigm (experiment 2,3, EEG) were used

New long-lived particle searches in heavy-ion collisions at the LHC

We show that heavy-ion collisions at the LHC provide a promising environment to search for signatures with displaced vertices in well-motivated new physics scenarios. Compared to proton collisions, they offer several advantages: (i) the number of parton level interactions per collision is larger, (ii) there is no pileup, (iii) the lower instantaneous luminosity compared to proton collisions allows one to operate the LHC experiments with very loose triggers, and (iv) there are new production mechanisms that are absent in proton collisions We focus on the third point and show that the modification of the triggers alone can increase the number of observable events by orders of magnitude if the long-lived particles are predominantly produced with low transverse momentum. Our results show that collisions of ions lighter than lead are well motivated from the viewpoint of searches for new physics. We illustrate this for the example of heavy neutrinos in the Neutrino Minimal Standard Model
