Binocular interaction in normal vision studied by pattern-reversal visual evoked potentials (PR-VEPS)Summa A. di Polo A. Tinazzi M. Zanette G. Bertolasi L. Bongiovanni L. G. Fiaschi A. Original ArticlesDOI:
10.1007/BFdi Summa, A., Polo, A., Tinazzi, M. et al. Ital J Neuro Sci (. doi:10.1007/BF
Monocular and binocular visual evoked potentials (VEPs) in response to different check sizes (15-21-38-84 minutes of arc) were studied in 14 subjects with normal visual acuity and stereopsis.The binocular VEP amplitude is slightly higher than the VEP amplitude on stimulation of the “better eye” and significantly higher than the VEP amplitude on stimulation of the “worse eye”; this effect is observed using small checks and almost exclusively involves N75-P100.Both the N75 and P100 peaks occur earlier after binocular than monocular stimulation. The shortening of the N75 mean latency is significantly greater than that of the P100 mean latency when larger check sizes are used.The mean latency of the N145 potential is not significantly different in monocular and binocular stimulus conditions. The slight summation effect and latency shortening in the binocular VEPs are not consistent with the hypothesis that it is the sum of separate monocular signals originating from the visual cortex that gives rise to the response. The early components of both monocular and binocular VEPs are thought to be of post-synaptic origin (outside layer 4c of area 17), where the imputs become mixed so that most cells receive information from both eyes.The amplitude enhancement of binocular VEPs, which mainly occurs when using small checks, may be related to the increase in the total amount of cortical activity representin this may account for binocular superiority in fine spatial resolution.The latency shortening in binocular conditions can be explained by considering that the critical determinant of the latency is the fundamental spatial frequency of the pattern. When coarse patterns are used, their effectiveness in parafoveal stimulation may affect the VEPs, with a significant contribution coming from the more peripheral retina. The enlargement of the visual field when the eyes see simultaneously may therefore further reduce the latency of the response when using the larger checks suitable for eccentric stimulation.VEPs Binocular vision Monocular vision Visual acuity Stereopsis [1]

Pigeon homing: Effects of manipulation of sensory experience at home siteN. E. BaldacciniS. BenvenutiV. FiaschiP. IoaléF. PapiArticleDOI:

During a treatment that lasted approximately 100 days beginning at fledging time, four groups of pigeons were kept for ten 3-day periods in an aviary of wire-netting located in Arnino. Here they could acquire a visual experience of the landmarks and leave for exercise flights. During these 3-day sojourns, the birds wore masks which prevented or limited their breathing through the nostrils. For the remaining time the pigeons were unmasked and closed in four cages outdoors that prevented them from seeing the country-side. The cages were of two types, ones with walls of horizontal strips that allowed the flow of air (pervious cages) and ones with vertical walls impervious to air currents (impervious cages). The four groups were kept under different conditions: 1) RP-birds were kept in a pervious cage in A 2) RI-birds, in an impervious cage in A 3) CP-birds, in a pervious cage in Miemo, 42 km SW of A 4) CI-birds, in an impervious cage in Miemo. The results of the test releases, carried out in a location 24.5 km SW of Arnino and 17.8 km NE of Miemo were the following:1) The RP-birds were home oriented, all returning to A 2) the RI-birds were erroneously oriented towards SW, 20 out of 24 returning to Arnino but more slowly than the RP-birds with 4 3) the CP-birds were oriented towards the site of the cage (Miemo), 4 returning to Arnino, 5 to Miemo with 8 4) the CI-birds are oriented at random, 5 returning to Arnino with 8 lost.The results indicate that the initial orientation is correct only in pigeons which have been exposed to winds with their nostrils free. They can return to their cage even if they have no visual experience of the surroundings. However, return to a location where the pigeons had visual experience but no olfactory experience is also possible.Batschelet, E.: Recent statistical methods for orientation data.
