Top-down modulation

Web1. okt 2024 · Here, we summarize recent findings on bottom-up and top-down factors that can modulate sensory processing and multisensory integration. We discuss cortical circuits that are responsible for modulation of multisensory processing based on recent rodent studies. We suggest that multisensory information is not a simple, fixed signal in the brain. WebThis study investigated top-down modulation of bottom-up attentional capture in children with autistic spectrum disorders (ASDs) and in a typically developing (TD) comparison group using a spatial-cuing task (Experiment 1) and a series of visual search tasks (Experiment 2) employing task-irrelevant distractors.

Web13. jan 2024 · In this story, TDM ( Top-Down Modulation) is shortly reviewed. It is found that by combining high-level and low-level features using TDM, many hard objects can be detected, and thereby a significant boost on the COCO benchmark. I chose to review this paper because some of the later state-of-the-art approaches such as YOLOv3 and … WebFor the subsequent P1 component, attentional modulations were clearly expressed and remained unaffected by these deviations. Collectively, these results suggest that spatial attention, unlike load or task relevance, can exert dissociable top-down modulatory effects at the C1 and P1 levels.
