The multifocal visual evoked potential (mfVEP) is largely generated in V1. To relate the electrical activity recorded from humans to recordings from single cells in nonhuman primate (V1) cortex, contrast-response functions for the human mfVEP were compared to predictions from a model of V1 activity (D. J. Heeger, A. C. Huk, W. S. Geisler, & D. G. Albrecht, 2000) based upon single-cell recordings from monkey V1 (e.g., D. G. Albrecht, 1995; D. G. Albrecht, W. S. Geisler, R. A. Frazor, & A. M. Crane, 2002; D. G. Albrecht & D. B. Hamilton, 1982; W. S. Geisler & D. G. Albrecht, 1997). A second purpose was to fully articulate the assumptions of this model to better understand the implications of this comparison. Finally, as the third purpose, one of these assumptions was tested. Monocular mfVEPs were obtained from normal subjects with a contrast-reversing dartboard pattern. The display contained 16 sectors each with a checkerboard. Both the sectors and the checks were scaled approximately for cortical ...
VEPs were recorded with three different spatial frequencies of stimulation in patients affected by idiopathic Parkinsonism and by Parkinsonian syndromes. The detection of VEP abnormalities in Parkinsons disease was dependent on the spatial frequency of the visual stimulus (a vertical square wave grating). The VEP latency was normal in Parkinsonian syndrome patients (except in one patient affected by familial Parkinsonism). Dopamine precursor therapy differently reduced the VEP latency, depending on the spatial frequency of the visual stimulus. These findings suggest that the dopaminergic mechanism involved in the generation of VEP delays is sensitive to stimulus spatial frequency. The study of VEPs before and after the administration of haloperidol confirmed this hypothesis. VEP latency did not correlate with the major clinical symptoms of Parkinsons disease and could not predict the results of chronic dopaminergic therapy.. ...

Substitute methadone is the currently recommended treatment of pregnant opioid-dependent women.23 Several observational studies have reported abnormalities of visual and neurologic development in infants of drug-misusing mothers prescribed substitute methadone in pregnancy,5-12,17 but to date there has been no prospective study of such infants, and so the prevalence of visual dysfunction in this population remains unknown.. We have previously described abnormal flash VEPs in newborn infants exposed to methadone in utero17 but these data were confounded by IUGR and gestation, and numbers were too small to investigate the individual effects of methadone and other illicit drugs. This larger cohort study has confirmed substantial differences between neonatal flash VEPs of infants exposed to methadone in utero and those of non-drug-exposed comparison infants and suggests that prescribed substitute methadone, rather than other illicit drugs, may be to blame. Reduced VEP amplitude with immature ...
Diabetes mellitus (DM) is a metabolic disorder which is characterised by hyperglycaemia resulting from defects in insulin secretion, insulin action or both. The long-term specific effects of DM include the development of retinopathy, nephropathy and neuropathy. Cardiac disease, peripheral arterial and cerebrovascular disease are also known to be linked with DM. Type 1 diabetes mellitus (T1DM) accounts for approximately 10% of all individuals with DM, and insulin therapy is the only available treatment. Type 2 diabetes mellitus (T2DM) accounts for 90% of all individuals with DM. Diet, exercise, oral hypoglycaemic agents and occasionally exogenous insulin are used to manage T2DM. The diagnosis of DM is made where the glycated haemoglobin (HbA1c) percentage is greater than 6.5%. Pattern-reversal visual evoked potential (PVEP) testing is an objective means of evaluating impulse conduction along the central nervous pathways. Increased peak time of the visual P100 waveform is an expression of ...
88 eyes of 48 consecutive patients were included for study, 20 male and 28 female, aged 57-94 (avg. 79).

Purpose: : Glaucoma diagnosis and management is based on the assessment of optic nerve structure and function. The conventional pattern-reversal visual evoked potential (VEP) technique has been used as an objective method of evaluating the visual pathway. We investigated the correlation between structural and functional damage in patients with asymmetric glaucoma using a fast transient VEP (ftVEP) device. Methods: : Twenty-three subjects with bilateral glaucoma (glaucomatous optic neuropathy + visual field defects) and visual acuity ≥ 20/25 underwent optical coherence tomography (Stratus OCT) for macular thickness measurement, scanning laser polarimetry with variable corneal compensation (GDx-VCC) for RNFL measurement and ftVEP (Diopsys, Inc., Pine Brook, NJ; 10 and 85% Michelson of contrast, acquisition time of 20s) in both eyes within 2 months. Asymmetric glaucoma was defined as a difference in MD of at least 3 dB (SITA Standard 24-2). The correlation between structural test results (OCT and ...
Sensory information processing in ACC networks is critical for ACC-related brain functions. Using in vivo whole-cell recording, we have investigated MP responses of layer II/III ACC neurons to sensory stimulation. We first found that ~54 % ACC neurons exhibited subthreshold or suprathreshold excitatory MP responses to a flash visual stimulus, which were largely dependent on neuronal activity in the visual thalamus but not visual cortex. We further found in an even larger population (~81 %) of ACC neurons that excitatory MP responses could also be evoked by a pain-related electrical stimulus. These findings may reflect potential mechanisms underlying the ACC function that involves information processing of sensory and noxious stimuli.. As a multimodal brain region, ACC has been known to be capable of responding to complex stimulation or tasks, including those related to reward [21-23] and aversive stimuli [7, 24-26] as well as attention [1, 9, 10, 27]. However, ACC neuronal activity in response ...

Visual Evoked Potentials (VEPs) are used in clinical applications in ophthalmology, neurology and extensively in brain computer interface (BCI) research. BCI literature covers steady state VEP (SSVEP) and code modulated VEP (c-VEP) BCIs along with sophisticated methods to improve information transfer rates (ITR). There is a gap of knowledge regarding the VEP adaptation dynamics, physiological generation mechanisms and relation with BCI performance. A simple dual display VEP switch was developed to test signatures elicited by non-isochronic, non-singular, low jitter stimuli at the rates of 10, 32, 50 and 70 reversals per second (rps). Non-isochronic, low-jitter stimulation elicits Quasi-Steady-State VEPs (QSS-VEPs) that are utilized for simultaneous generation of transient VEP and QSS-VEP. QSS-VEP is a special case of c-VEPs and it is assumed that it shares the similar generators of the SSVEPs. Eight subjects were recorded and the performance of the overall system was analyzed by means of Receiver
A portable device for detecting multifocal steady-state visual evoked potentials associated with visual field stimulation is being developed as an objective test for identifying glaucoma-related visual function loss.
In adults, certain regions of the brains visual cortex respond preferentially to specific types of input, such as faces or objects-but how and when those preferences arise has long puzzled neuroscientists.
Many researchers have taken the Colavita effect to represent a paradigm case of visual dominance. Broadly defined, the effect occurs when people fail to respond to an auditory target if they also have to respond to a visual target presented at the same time. Previous studies have revealed the remarkable resilience of this effect to various manipulations. In fact, a reversal of the Colavita visual dominance effect (i.e., auditory dominance) has never been reported. Here, we present a series of experiments designed to investigate whether it is possible to reverse the Colavita effect when the target stimuli consist of repetitions embedded in simultaneously presented auditory and visual streams of stimuli. In line with previous findings, the Colavita effect was still observed for an immediate repetition task, but when an n-1 repetition detection task was used, a reversal of visual dominance was demonstrated. These results suggest that masking from intervening stimuli between n-1 repetition targets was

A visual parking guide, more particularly, a thin flat surface, divided into three zones, with a multitude of markings in each zone, to assist drivers of varying heights to park their car in a safe parking position. The visual parking guide is mountable on a supporting structure such that at least a portion of the parking guide is within the field of view of the driver. By parking the vehicle at a preferred distance from a stationary structure and aligning a fixed point relative to the vehicle with one of the multitude of markings on the visual parking guide, the driver can determine a reference point to use as a means to determine the safe parking position.

This study discusses the combined effect of auditory and visual factors on comprehensive comfortableness. We used the concept of harmonious sensation to explain this effect. To clarify the function of this sensation, we conducted two psychological experiments. The result shows that harmonious sensation, visual and auditory comfortableness has an equal influence on comprehensive comfortableness. The effect of harmonious sensation was varied according to the degree of visual and auditory comfortableness; This effect increased as the difference in the degree of comfortableness between visual and auditory factors becomes wide.. ...
