Two recent imaging studies have shed new light on information representation in human parahippocampal cortex. Despite their different approaches, the two studies both support the view that this brain region represents space at an elementary level.

The role of the physiological processes involved in human vision escapes clarification in current literature. Many unanswered questions about vision include: 1) whether there is more to lateral inhibi...
Associations between co-occurring stimuli are formed in the medial temporal lobe (MTL). Here, we recorded from 508 single and multi-units in the MTL while participants learned and retrieved associatio...
The presubiculum is part of the parahippocampal spatial navigation system and contains head direction and grid cells upstream of the medial entorhinal cortex. This position within the parahippocampal ...
The aim of the study was to evaluate the diagnostic value of two measurement techniques in patients with cognitive impairment - automated volumetry of the hippocampus, entorhinal cortex, parahippocamp...
In patients with central visual field scotomata, a large part of visual cortex is not adequately stimulated. Patients often use a new eccentric fixation area on intact peripheral retina ("preferred re...
This study will examine whether direct current (DC) polarization (electrical stimulation) of the visual cortex can cause a temporary improvement of vision in an amblyopic eye of an adult. ...
Panic disorder is one of the most prevalent and disabling psychiatric disorders. Brain regions such as amygdala, hippocampus, periaqueductal gray (PAG), locus coeruleus, parahippocampal g...
This study will determine if the interdisciplinary team low vision rehabilitation program is more effective than basic low vision care provided by an optometrist working alone in improving...
The purpose of this study is to see if Stendra causes any changes in vision, eye pressure, pupil dilation, and color vision in healthy males.
Amblyopia is an impairment in spatial vision caused by asymmetry in the quality of visual input across the two eyes during childhood. It is difficult to treat in adulthood because the visu...
The cytoarchitecturally well-defined area of multilaminate cerebral cortex on the medial aspect of the parahippocampal gyrus, immediately caudal to the olfactory cortex of the uncus. The entorhinal cortex is the origin of the major neural fiber system afferent to the hippocampus, the so-called PERFORANT PATHWAY. (Stedman, 25th ed)
Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).
Area of the occipital lobe concerned with vision.
A neurosurgical procedure that removes the anterior TEMPORAL LOBE including the medial temporal structures of CEREBRAL CORTEX; AMYGDALA; HIPPOCAMPUS; and the adjacent PARAHIPPOCAMPAL GYRUS. This procedure is generally used for the treatment of intractable temporal epilepsy (EPILEPSY, TEMPORAL LOBE).
Artificial device such as an externally-worn camera attached to a stimulator on the RETINA, OPTIC NERVE, or VISUAL CORTEX, intended to restore or amplify vision.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
