A search starts with a keyword or normal guided navigation, but quickly becomes driven visually.
The relation between stimulus strength C and the aspect of DV drift that is driven by visually evoked sensory evidence is represented by parameter k i (see also Figure 4A,B).
Moreover, in visual cortex, this visually driven activity increases when the (retinal) stimulus size is made larger in the visual field (Ito et al. 1995; Allison et al. 1999; Ashbridge et al. 2000; Op de Beeck and Vogels 2000; Konkle and Oliva 2012).
So whilst Hulslander et al. could make conclusions about more general sensory processing, whether or not individual differences in visual processing specifically targeting visually driven parietal functioning can be associated with reading ability after controlling for general intelligence has not been established.
There may thus be other visually driven areas within the visual wulst which do not show retinotopy, but may, in accordance with findings in mammals, be with or without a more complex topographical mapping and/or of neurons not responding to moving bars [67].
Importantly, such decreased fMRI activity to increased visual stimulation in the DMN is opposite in sign to that typically found when measuring visually driven fMRI responses throughout primate visual cortex.
All animals were maintained overnight in total darkness followed by 1-h light stimulation upon removal of the hoods to induce maximal visually driven IEG expression in the visual cortex (Arckens et al. 2000; Van der Gucht et al. 2002).
Thus the current study aimed to investigate several purported parietal functions as a means of assessing whether supposed impairment in earlier M-pathway functioning in dyslexia would lead to an impairment of all visually driven parietal functions receiving their visual projection via the dorsal stream and whether this was related to general nonverbal problem solving ability.
We applied in situ hybridization for measuring changes in the visually driven expression of the activity reporter gene zif268, to visualize possible differences in activation of the central and peripheral region of primary visual cortices 17 and 18 as a function of age and visual manipulation.
For instance, rTMS at the frequency of 1 Hz applied to the visual cortex of the cat, produced a significant reduction in visually driven responses recorded simultaneously in layer 6 of V1 (the source of the feedback) and in the dLGN [10] (see also methods section).
Numerous studies have reported category-selective activity in the vicinity of LIM, including visually driven selectivity for faces or biological motion in STS, and/or a cognitively driven site selective for ToM (for review, see Allison et al. 2000; Spreng et al. 2009; Kanwisher 2010).
