Figure-ground modulation in awake primate thalamus.
Figure-ground discrimination refers to the perception of an object, the figure, against a nondescript background. Neural mechanisms of figure-ground detection have been associated with feedback interactions between higher centers and primary visual cortex and have been held to index the effect of global analysis on local feature encoding. Here, in recordings from visual thalamus of alert primat...

Visual processes deal with analyzing images and extracting information from them. They play an important role in many of todays industries, e.g., in the medical instrument industry, the electronic and micro-electronic industry, the movie industry, the robotics industry, and in many other elds which require automatic extraction of visual information from images. One of the major di culties in im...

This paper proposes a new, e cient, gure from ground discrimination method. This algorithm is based on the assumption that background data features can be more easily detected than gure data features, thus emphasizing the background detection task (and implying the name of the method). Along the iterative labeling process, data features are sequentially and permanently labelled as "background",...

متن کاملAttention-related, cross-modality modulation of somatosensory neurons in primate ventrobasal (VB) thalamus.
Attention-related modulation (AM) of the somatosensory responses of single neurons has been demonstrated in the cerebral cortex and medullary dorsal horn, but not in the ventrobasal thalamus. The somatically evoked activity was recorded of single units in the ventral posterior lateral thalamus (VPL) of awake monkeys while they detected the termination of task-relevant somatic or visual stimuli....
