1.1Sensory Cortex Sensory cortexrefers to all cortical areas associated with sensory function. In the case of vision, this includes virtually all of theoccipital cortexand much of the temporal andparietal cortex. An object must be perceived before it can be categorized, so an intact sensory cortex...

(theconvolutedouter shell of the brain). Different sensory receiving areas are localized in particular regions of the cortex—e.g., occipital lobes in the back of the brain for vision, temporal lobes on the sides for hearing, and parietal lobes toward the top of the brain fortactilefunction....

We review and apply a computational theory based on the hypothesis that the feedforward path of the ventral stream in visual cortex's main function is the encoding of invariant representations of images. A key justification of the theory is provided by a result linking invariant representations to...
We found that the temporal window in which primary visual cortex is required for the detection of identical visual stimuli was extended when task demands were increased via an additional sensory modality that had to be monitored. Late-onset optogenetic inactivation preserved bottom-up, early-onset ...
30. Suppressing late activity in the primary somatosensory cortex impairs tactile detection30, whereas in primary visual cortex it has been argued that feedforward activity is sufficient for visual discrimination6,31. We hypothesize that the cognitive demands of a task, which are captured by the ...
- touch: touch receptors throughout the body in complex travel pathways converging into the somatosensory cortex; somatic organization allows us to precisely locate and discriminate between fine and crude touch, vibration, pressure, temperature, itch, and pain ...
As was shown in Part I the function of such rhythms is to keep the sensory areas in an idling state – the state in which the cortex does not actively process the sensory information but can be switched to the active processing mode in a fraction of a second. View chapter Review article...
