Sighting ocular dominance magnitude varies with test distance

Clinical and Experimental Optometry (2017)

Raymond H. Ho Benjamin Thompson Raiju J. Babu Kristine Dalton

Ocular dominance can be defined as the preference of an individual for viewing with one eye over the other for particular visual tasks. It is relevant to monovision contact lens wear, cataract surgery and sports vision. Clinically, the measurement of ocular dominance is typically done at an arbitrary distance using a sighting test, such as the hole-in-card method that has a binary outcome. We investigated the effect of test distance on ocular dominance measured using a binocular sighting test that provided a continuous measurement of dominance.Ten participants with normal binocular vision took part in this study. Their binocular sighting ocular dominance and phorias were measured at one, two, four, eight and 10 metres. During the dominance tests participants made a binocular alignment judgment and then were asked to indicate the relative alignment of each eye using a visual analogue scale as a reference.Eight participants had strong ocular dominance (five right, three left). For these participants, there was a significant increase in the magnitude of dominance with increasing test distance (p < 0.001). This could not be fully explained by changes in convergence demand. Two participants showed very weak ocular dominance across all test distances (p > 0.05), despite changes in convergence demand.When ocular dominance is present, its magnitude varies significantly with test distance. This has significant implications for the accurate measurement of ocular dominance in the clinic and may reflect the neural processes that influence eye preference.

A Comparative Investigation of Mode Mixing in EEG Decomposition Using EMD, EEMD and M-EMD

Raymond H. Ho Kevin Hung

This paper presents and discusses the empirical mode decomposition method (EMD), its mode mixing problem and the primary causes of it. The ensemble EMD (EEMD) and masking EMD (M-EMD) methods are discussed as solutions for the mode mixing problem. Both improved methods were applied to process an EEG signal and the results were compared. The M-EMD provided the best result making good separation of the EEG signal into delta, theta, alpha, and beta band signals.

Roleofsubstance Pinsuppressing growth hormonerelease in

M. Arisawa G. D. SNYDERt L. DEPALATISt Raymond H. Ho Rong-xiang Xu

Toevaluate apossible physiological role of endogenous substance P(SP) inthecontrol ofgrowth hormone (GH;somatotropin) secretion, aspecific antiserum against SP (anti-SP) wasinjected intraventricularly (3I1into thethird cerebral ventricle) inunanesthetized unrestrained normal male rats. Control ratsreceived anequivalent volume ofnormal rabbit serum(NRS). Intraventricular iniection oftheNRS lowered plasma GHconcentrations significantly. Thelowering wasdetected onfirst measurement at10minafter injection and wasmaximal at30min.Thiswasfollowed byareturn toward theinitial levels. Thirdventricular injection ofantiserum significantly increased plasma GHincomparison with control animals injected withNRS.Theeffect wasobserved within 10-20min,andlevels remained elevated forthe120-min duration oftheexperiment.

A developmental study of substance‐P, somatostatin, enkephalin, and serotonin immunoreactive elements in the spinal cord of the North American opossum

The Journal of Comparative Neurology (1983)

F.J. Ditirro George F. Martin Raymond H. Ho

Abstract Substance‐P (SP), somatostatin (SOM), enkephalin (ENK), and serotonin (5‐HT) immunoreactive elements were studied in the spinal cord of the opossum at each 10‐mm snout‐rump (S‐R) length interval between 18 (newborn) and 127 mm (75 days after birth). The opossum is born 12 days after conception and undergoes a protracted postnatal development in an external pouch which makes it a good model for such a study. SP‐like immunoreactivity was detected in the newborn opossum; it was found within fibers located mainly in the dorsolateral marginal zone. SP‐like immunoreactive fibers soon become fairly abundant within presumptive laminae I, II, and X and were scattered within other areas of the spinal gray matter including the intermediolateral cell column. By 30 days after birth (57 mm S‐R length), the adult distribution was established. SOM‐like immunoreactivity was not detected within the spinal cord at birth. However, by postnatal day 5 (24 mm S‐R length) it was present in fibers which were numerous within the marginal zone and present within presumptive laminae I–III as well as in more ventral areas of the gray matter. By approximately postnatal day 30, evidence for SOM immunoreactivity was found within all areas of the spinal gray matter expected from studies of the adult opossum. ENK‐like immunoreactivity was present at birth within fibers of the dorsolateral marginal zone. By postnatal day 30 ENK immunoreactive fibers were found within most of the areas containing them in the adult animal, except for laminae I and II. ENK‐like immunoreactivity was not observed in laminae I and II until approximately postnatal day 50 (84 mm S‐R length). Fibers showing 5‐HT‐like immunoreactivity were remarkably abundant within the cervical marginal zone at birth but sparse at lumbosacral levels. They were found within laminae IV–Xby postnatal day 15 (35 mm S‐R length) and within the intermediolateral cell column by at least day 30. The adult distribution was not present until approximately 50 days after birth when 5‐HT‐like immunoreactivity was found within fibers of laminae I and II. Demonstration of SOM‐, ENK‐, and 5‐HT‐like immunoreactivities in neuronal somata of the spinal cord was age dependent. Our results suggest that axons containing SP, SOM, ENK, and 5‐HT are present within the opossum's spinal cord very early in development and that they grow into specific spinal targets in an orderly sequence.

Immunohistochemical localization of substance P, somatostatin, enkephalin, and serotonin in the spinal cord of the northern leopard frog, Rana pipiens

The Journal of Comparative Neurology (1988)

Abstract Using the indirect antibody peroxidase‐antiperoxidase method of Sternberger, we localized substance P (SP), somatostatin (SOM), enkephalin (ENK), and serotonin (5HT, 5‐hydroxytryptamine) in the spinal cord of Rana pipiens . This is the first study to demonstrate all four substances in adjacent sections of frog spinal cord. The distribution patterns of ENK, SP, SOM, and 5HT in our study differ from that described for laminae I and II in amniotes. A high density of ENK, SP, and SOM fibers is present in a band ventral to the dorsal terminal field of cutaneous primary afferent fibers and slightly overlapping the ventral terminal field of muscle primary afferent fibers. However, a high density of 5HT fibers is present in the dorsal terminal field.
