Synchronous information presented in 40-Hz flicker enhances visual feature binding

Article Abstract:

The perception of the entirety of an object during visual object perception is made possible by the binding of discrete stimulus by synchronization of spatially distributed neural assemblies in the neocortex oscillating at a rate of 40 Hertz. Figural priming under modulation condition simulating a 40 Hertz cycle was used to demonstrate this synchronization. Results lend support to the preattentive coding of visual objects via externally entrained 40-Hertz-feature binding mechanism.

Dissociable neural subsystems underlie abstract and specific object recognition

Article Abstract:

A study was conducted to show that dissociable neural subsystems operate in parallel to underlie visual object recognition. Dissociable subsystems were assumed to accommodate abstract-category and specific-exemplar object recognition. Findings also indicated that an abstract-category subsystem operates more efficiently than a specific-exemplar subsystem in the left hemisphere while a specific-exemplar subsystem is more effective than an abstract-category subsystem in the right.
