Sensory loss in either the eyes or the ears affects our ability to recognize emotions, but does loss in both eyes and ears further worsen our ability to interpret multisensory signals? In a recent paper published in the journal “Vision … Continued
The two hemispheres of the brain process information somewhat differently. In other words, we have two brains in one, a phenomenon referred to as “brain lateralization”. Can a single unifying principle explain all the instances of brain lateralization? In a … Continued
Assessing the integrity of the optic nerve (ON), the first section of the neural wiring between the eye and the brain, is important in ophthalmology for diagnostic purposes and follow-up. Commonly, this is done using optical coherence tomography (OCT), yet … Continued
Can the directionality of BOLD activity, as measured using fMRI, provide meaningful information at a very fine scale? In a recent paper, published in the journal Cerebral Cortex, Nicolas Gravel and colleagues show that it does. Using advanced models, they … Continued
Does having a visual field defect affect the representation of the visual world in the human brain? In a paper in the journal “Neuroimage”, Gokhul Prabhakaran and colleagues report that it does. Using fMRI, they find that neurons in the … Continued
Can an eye exam become literally as simple as watching a movie? In a recent paper in the Journal of Vision, Birte Gestefeld and colleagues show that the idea is perhaps not that far fetched. Based on the eye-movements made … Continued
The majority of emotional expressions used in daily communication are multimodal and dynamic in nature, but relatively little is known yet about how we adapt our perceptual strategies to the presence or absence of certain information. In a recent paper … Continued
What if an eye health exam could become as simple as following a moving and jumping dot on a screen for a few minutes? In a paper in the journal “Frontiers in Neurology”, Alessandro Grillini and co-authors show that the … Continued
Using fMRI to determine the presence of actual cortical reorganization following ocular or cortical lesions requires being aware of many potential pitfalls. In a recent paper in the journal “Neuroimage”, Gokul Prabhakaran and co-authors report on one more such an … Continued
The incorporation of Virtual Reality (VR) and Eye tracking can provide advantages for assessment and training in visual rehabilitation to both patients and therapists. Birte Gestefeld and colleagues conclude this in their paper in the journal “Vision Rehabilitation International”. You … Continued
