Scientists have pondered the perceptual effects of ocular motion, and those of its counterpart, ocular stillness, for over 200 years. The unremitting ‘trembling of the eye’ that occurs even during gaze fixation was first noted by Jurin in 1738. In 1794, Erasmus Darwin documented that gaze fixation produces perceptual fading, a phenomenon rediscovered in 1804 by Ignaz Paul Vital Troxler. Studies in the twentieth century established that Jurin’s ‘eye trembling’ consisted of three main types of ‘fixational’ eye movements, now called microsaccades (or fixational saccades), drifts and tremor. Yet, owing to the constant and minute nature of these motions, the study of their perceptual and physiological consequences has met significant technological challenges. Studies starting in the 1950s and continuing in the present have attempted to study vision during retinal stabilization—a technique that consists on shifting any and all visual stimuli presented to the eye in such a way as to nullify all concurrent eye movements—providing a tantalizing glimpse of vision in the absence of change. No research to date has achieved perfect retinal stabilization, however, and so other work has devised substitute ways to counteract eye motion, such as by studying the perception of afterimages or of the entoptic images formed by retinal vessels, which are completely stable with respect to the eye. Yet other research has taken the alternative tack to control eye motion by behavioural instruction to fix one’s gaze or to keep one’s gaze still, during concurrent physiological and/or psychophysical measurements. Here, we review the existing data—from historical and contemporary studies that have aimed to nullify or minimize eye motion—on the perceptual and physiological consequences of perfect versus imperfect fixation. We also discuss the accuracy, quality and stability of ocular fixation, and the bottom–up and top–down influences that affect fixation behaviour. © 2017 The Author(s) Published by the Royal Society.

The NYS-ITRP is a research training program focused on building HIV research capacity in the former Soviet Union, combining resources from SUNY Downstate, SUNY Albany, and multiple training units throughout New York State. The organization began their work in 1994, addressing similar HIV epidemic conditions in the newly independent nations of Czech Republic, Hungary, and Poland. "While HIV incidence is declining globally, Eastern Europe and Central Asia are regions where HIV infections continue to rise," says Distinguished Service Professor Jack DeHovitz, MD, MPH, MHCDS, FACP, the director of the program. "This new grant, combined with a similar grant awarded to the NYS-ITRP for Kazakhstan in 2016, places SUNY Downstate and its affiliates as a leader in HIV research training in the region," DeHovitz says. The program is the only HIV research training in Eastern Europe and Central Asia supported by the National Institutes of Health Fogarty International Center. Despite notable improvements in responding to the epidemic, access to antiretroviral therapy remains low and institutional barriers impede access to care by substance users. Ukraine, the largest country in Europe, is home to the continent's most volatile HIV epidemic with an adult prevalence of 1.1%. It has experienced multiple crises since it emerged from the Soviet Union in 1991 including two revolutions, the 2014 Crimean invasion, and the ongoing war in east and southern Ukraine. Independence from the Soviet Union also coincided with the emergence of an IDU epidemic. It has been estimated that this country of 45.5 million now has over 300,000 injection drug users, contributing to large increases in both HIV and hepatitis C virus (HCV) infections. The program will work in collaboration with the School of Public Health of National Ukraine Kyiv-Mohyla Academy (SPH NaUKMA) and a research-focused nongovernmental organization, the Ukrainian Institute on Public Health Policy (UIPHP). Training opportunities developed through this funding include the recruitment and training of HIV Research Scholars, and graduates will receive enhanced training in implementation science, biostatistics, epidemiology, and behavioral health. SUNY Downstate Medical Center, founded in 1860, was the first medical school in the United States to bring teaching out of the lecture hall and to the patient's bedside. A center of innovation and excellence in research and clinical service delivery, SUNY Downstate Medical Center comprises a College of Medicine, College of Nursing, College of Health Related Professions, a School of Graduate Studies, a School of Public Health, University Hospital of Brooklyn, and a multifaceted biotechnology initiative including the Downstate Biotechnology Incubator and BioBAT for early-stage and more mature companies, respectively. SUNY Downstate ranks twelfth nationally in the number of alumni who are on the faculty of American medical schools. More physicians practicing in New York City have graduated from SUNY Downstate than from any other medical school. For more information, visit www.downstate.edu.

Parkinsonism and Related Disorders | Year: 2013

Purpose: The article aims to review foveal involvement in Parkinson's disease. Scope: Clinical observations as well as electrophysiological and anatomical studies in animal models provide evidence that Parkinson's disease (PD) affects vision. The retina is the most distal locus of visual dysfunction in PD as shown by electroretinographic (ERG) and optical coherence tomographic (OCT) studies. Thinning of the retinal nerve fibre layer (RNFL) and the fovea has been reported in PD. This review summarises retinal physiology and foveal visual dysfunction in PD and quantification of retinal thinning as reported in different studies and using different instruments. At this point due to methodological diversity and relatively low number of subjects studied, a meta-analysis is not yet possible. Results obtained on one equipment are not yet transferable to another. The author also briefly alludes to some links of visual processing deficits beyond visual detection, such as visual discrimination, visual categorisation and visuospatial orientation in PD. Conclusions: There are some promising results suggesting the potential applicability of ST-Oct as a biomarker in PD. Furthermore, these data raise some interesting neurobiological questions. However, there are identifiable pitfalls before OCT quantification may be used as a biomarker in PD. Analysis standardisation is needed on a larger than existing healthy and patient population. Furthermore, longitudinal studies are needed. The exact relationship between retinal foveal deficits and visuo-cognitive impairment in PD remains a challenging research question. © 2012 Elsevier Ltd.

The onset of puberty is associated with alterations in mood as well as changes in cognitive function, which can be more pronounced in females. Puberty onset in female mice is associated with increased expression of α4βδ γ-amino-butyric acid-A (GABAA) receptors (GABARs) in CA1 hippocampus. These receptors, which normally have low expression in this central nervous system (CNS) site, emerge along the apical dendrites as well as on the dendritic spines of pyramidal neurons, adjacent to excitatory synapses where they underlie a tonic inhibition that shunts excitatory current and impairs activation of N-methyl-D-aspartate (NMDA) receptors, the trigger for synaptic plasticity. As would be expected, α4βδ expression at puberty also prevents long-term potentiation (LTP), an in vitro model of learning which is a function of network activity, induced by theta burst stimulation of the Schaffer collaterals to the CA1 hippocampus. The expression of these receptors also impairs spatial learning in a hippocampal-dependent task. These impairments are not seen in δ knock-out (-/-) mice, implicating α4βδ GABARs. α4βδ GABARs are also a sensitive target for steroids such as THP ([allo]pregnanolone or 3α-OH-5α[β]-pregnan-20-one), which are dependent upon the polarity of GABAergic current. It is well-known that THP can increase depolarizing current gated by α4βδ GABARs, but more recent data suggest that THP can reduce hyperpolarizing current by accelerating receptor desensitization. At puberty, THP reduces the hyperpolarizing GABAergic current, which removes the shunting inhibition that impairs synaptic plasticity and learning at this time. However, THP, a stress steroid, also increases anxiety, via its action at α4βδ GABARs because it is not seen in δ-/- mice. These findings will be discussed as well as their relevance to changes in mood and cognition at puberty, which can be a critical period for certain types of learning and when anxiety disorders and mood swings can emerge. © 2013 Smith.

Evidence for a genetic basis for stroke comes from twin and family studies and from the occurrence of a number of uncommon monogenic disorders, but the contribution of genetic factors identified for stroke so far is small. Advances in genetics and genomics may permit new insights. In recent genome-wide association studies, a number of single-nucleotide polymorphisms have been associated with specific stroke subtypes and major stroke risk factors such as diabetes and atrial fibrillation. These await replication. Studies of messenger ribonucleic acid expression have also shown promise for the development of genomic signatures for stroke classification. Stroke and coronary heart disease share some features of pathophysiology, risk, and treatment, and their genetic and genomic bases also appear to overlap. © 2010 American College of Cardiology Foundation.

The haematological and neurological consequences of cobalamin deficiency define the essential role of this vitamin in key metabolic reactions. The identification of cubilin-amnionless as the receptors for intestinal absorption of intrinsic factor-bound cobalamin and the plasma membrane receptor for cellular uptake of transcobalamin bound cobalamin have provided a clearer understanding of the absorption and cellular uptake of this vitamin. As the genes involved in the intracellular processing of cobalamins and genetic defects of these pathways are identified, the metabolic disposition of cobalamins and the proteins involved are being recognized. The synthesis of methylcobalamin and 5′-deoxyadenosylcobalamin, their utilization in conjunction with methionine synthase and methylmalonylCoA mutase, respectively, and the metabolic consequences of defects in these pathways could provide insights into the clinical presentation of cobalamin deficiency. © 2009 Blackwell Publishing Ltd.
