WebTop-down attentional modulation in autistic spectrum disorders is stimulus-specific. This study investigated top-down modulation of bottom-up attentional capture in children with … Web7. jún 2007 · While the link between specific top-down influences and brain states is an intriguing idea, and while fMRI studies have related to a certain extent the workings of one of these prior networks to top-down modulation (Corbetta and Shulman, 2002), some caveats remain. First, it will be valuable to demonstrate a direct link between the different ...

WebIn classical theories of automaticity, automatic processes are usually thought to occur autonomously and independently of higher level top-down factors (e.g., Posner & Snyder, 1975). However, already Neumann (1984) pointed out that the cognitive system has to be configured in a certain way for automatic processes to occur. In extension of his work, I … Web16. okt 2024 · Our analyses identified the middle and inferior frontal cortex as subregions that are most involved in this top–down attentional modulation, corroborating …
WebWe conclude that ERP C1 can be top-down modulated in a task-specific manner by high-level perceptual learning, so that C1 changes may not necessarily indicate plasticity in the … Web20. dec 2016 · Table 2: Top-Down Modulation network design for VGG16, ResNet101 and InceptionResNetv2. Notice that t out VGG16 is much smaller than 512, thus requiring fewer parameters in RPN and RCN modules. Also note that it is important to keep t out fixed for ResNet101 and InceptionResNetv2 in order to utilize pre-trained RPN and RCN modules …
