To characterize the organization and plasticity of the trigeminal reflex blink circuit, we interacted blink-evoking supraorbital (SO) and infraorbital (IO) nerve stimuli in alert rats. Stimulation of either trigeminal branch produced a short-lasting inhibition followed by a longer-lasting facilitation of blinks evoked by stimulating the other nerve. When IO stimulation evoked a smaller blink th...

We explore the temporal attention function in a non-clinical sample of adolescents varying in impulsivity, as assessed with the Barratt Impulsiveness Scale. In a Rapid Serial Visual Presentation task, in which two targets (T(1) and T(2)) were presented in close temporal proximity among distractors, participants tried to identify T(1) and detect T(2) in one (dual-task) experiment and only to det...

We present the first purely event-based approach for face detection using an ATIS, a neuromorphic camera. We look for pairs of blinking eyes by comparing local activity across the input frame to a predefined range, which is defined by the number of events per second in a specific location. If within range, the signal is checked for additional constraints such as duration, synchronicity and dist...

OBJECTIVE To investigate whether the human cerebellum takes part in fear conditioned potentiation of the acoustic blink reflex. METHODS A group of 10 cerebellar patients (eight patients with lesions involving the medial cerebellum, two patients with circumscribed lesions of the cerebellar hemispheres) was compared with a group of 16 age and sex matched healthy control subjects. The fear condi...

With the wide applications of user authentication based on face recognition, face spoof attacks against face recognition systems are drawing increasing attentions. While emerging approaches of face antispoofing have been reported in recent years, most of them limit to the non-realistic intra-database testing scenarios instead of the crossdatabase testing scenarios. We propose a robust represent...

Illusory conjunctions in the time domain are errors made in binding stimulus features presented In the same spatial position in Rapid Serial Visual Presentation (RSVP) conditions. Botella, Barriopedro, and Suero (2001) devised a model to explain how the distribution of responses originating from stimuli around the target in the series is generated. They proposed two routes consisting of two seq...

An inefficient visual search task can be facilitated if half the distractor items are presented as a preview prior to the presentation of the remaining distractor items and target. This benefit in search is termed the preview effect . Recent research has found that a preview effect can still occur if the previewed items disappear before reappearing again just before the search items (the ‘‘top-...
