Monocular deprivation (MD) for a few days during a critical period of development leads to loss of cortical responses to stimulation of the deprived eye. Despite the profound effects of MD on cortical function, optical imaging of intrinsic signals and single-unit recordings revealed that deprived eye responses and orientation selectivity recovered a few hours after restoration of normal binocul...

In human (D. H. Baker, T. S. Meese, & R. J. Summers, 2007b) and in cat (B. Li, M. R. Peterson, J. K. Thompson, T. Duong, & R. D. Freeman, 2005; F. Sengpiel & V. Vorobyov, 2005) there are at least two routes to cross-orientation suppression (XOS): a broadband, non-adaptable, monocular (within-eye) pathway and a more narrowband, adaptable interocular (between the eyes) pathway. We further charact...

all tumours, of which 6% 7%2 are gastric) but they must be considered in the differential diagnosis of patients with malignant tumours and diplopia caused by limitation on the abduction of the eye. It is possible, although unusual, to find orbital metastasis involving the extraocular muscles in the absence of previously known neoplastic disease (2% 15%)3 just as it happened with this patient, i...

Despite surgical intervention, orbital floor fractures are associated with risks of persisting sensibility disturbances, enophthalmos and diplopia. Cheek asymmetry and trismus may result when the zygoma is dislocated. In evaluating the surgical results patients’ experiences of the outcomes have to be investigated. To investigate sequelae a questionnaire was sent to 107 patients previously treat...
