In this paper an approach for the automatic extraction and evaluation of road networks from MOMS-2P imagery is proposed. Due to the limited spatial resolution of the images for the specified task a road model purely based on local criteria is rather weak, and therefore a significant number of false alarms are to be expected. A model is defined based on the local, regional, and global properties...

A mismatch between auditory sensation and expectant imagery of syllables elicited a possible equivalent of mismatch negativity in a previous study. The purpose of this study was to verify whether auditory imagery from musical notation could also mediate such imagery-based mismatch negativity. Neuromagnetic recording was obtained from eight musicians, who were instructed to identify unpredictabl...

Mental imagery is a critical cognitive function, clinically important, but poorly understood. When visual objects are perceived, many of their sensory, semantic and emotional properties are represented in occipitotemporal cortex. Visual imagery has been found to activate some of the same brain regions, but it was not known what properties are re-created in these regions during imagery. We there...

Farah (1989) reported that point threshold stimuli are detected better if they appear at spatial locations in the visual field that are covered by an image. By replicating her experiment with 3 instead of the original 2 images, we found that the effect depends on the shape of the mentally projected image. A second experiment with 9 different shapes revealed that the effect is modulated by the c...
