The extrastriate cortex is the part of the visual cortex that is located next to the striate cortex. The extrastriate cortex consists of multiple brain areas involved in processing specific features of visual information.
Focal cortical seizures result from local and widespread propagation of excitatory activity. Here the authors employ widefield calcium imaging in mouse visual areas to demonstrate that these seizures start as local synchronous activation and then propagate along the connectivity that underlies normal sensory processing.
V2 neurons exhibit complex and diverse selectivity for visual features. Here the authors use a statistical analytical framework to model V2 responses to natural stimuli and find three organizing principles, chief among them is the cross-orientation suppression that increases response selectivity.
Attention changes correlations between neuronal responses. In this study, Verhoef and Maunsell use multielectrode recordings in monkeys to reveal a link between normalization mechanisms, correlated neuronal activity and attention. The findings show that normalization mechanisms shape response correlations and that these correlations change when attention biases normalization mechanisms.
A study combines monkey behavioral testing with electrical stimulation of face patches, located with functional MRI and studied electrophysiologically, to probe the behavioral relevance of the face patches' selectivity.
A study demonstrates that learning different character sets produces a repeatable arrangement of distinct cortical modules, suggesting that a preexisting cortical architecture is repurposed during learning.
Single-unit recording in primate cortical area MT shows surprising sensitivity to depth defined by dynamical perspective cues. Depth might then be computed through recurrent circuits involving signals downstream of MT.
