Adaptive encoding in the visual pathway
Network: Computation in Neural Systems, 2003In a natural setting, the mean luminance and contrast of the light within a visual neuron's receptive field are constantly changing as the eyes saccade across complex scenes. Adaptive mechanisms modulate filtering properties of the early visual pathway in response to these variations, allowing the system to maintain differential sensitivity to ...

Neurology, 1996 To the Editor: In a recent study of albinism performed by Hedera et al. [1] utilizing the BOLD technique of functional MRI the authors stated that nystagmus was the likely reason for a decreased response …

Intracranial pathology of the visual pathway
European Journal of Radiology, 2004Intracranial pathologies involving the visual pathway are manifold. Aligning to anatomy, the most frequent and/or most important extrinsic and intrinsic intracranial lesions are presented. Clinical symptoms and imaging characteristics of lesions of the sellar region are demonstrated in different imaging modalities.

Plain film Plain film radiography is no longer used routinely for the evaluation of orbital pathology, but familiarity with normal anatomy remains important when reviewing emergency department trauma radiographs (Fig. 2.1). Cross-sectional anatomy The primary imaging modalities used to examine the orbit and visual pathways in clinical ...

Gliomas of the Anterior Visual Pathway
Journal of Neuro-Ophthalmology, 1994Gliomas of the anterior visual pathway are rare orbital lesions accounting for 65% of all intrinsic optic nerve tumors. These lesions occur principally among children in the first decade of life. They appear to be true neoplasms that characteristically show early growth, followed by stability in many patients.

Functional magnetic resonance imaging (fMRI) of the human brain provides images of changes in local blood flow and oxygenation that are evoked by sensory, motor, or cognitive events. Functional MRI has been used since 1991 [1] to identify areas of the brain that respond to visual stimulation and the performance of vision-related tasks.

Visual Attention And the Parallel Visual Pathways
2002Before examining the differential role played by the two major parallel visual pathways in attention I should like to very briefly review the current status of the parvo-magno functional segregation at various levels of the visual pathways, mainly referring to primates.

Probably no other intracranial tumor of childhood has been the subject of as many reports, with as many differing recommendations for treatment, as visual pathway gliomas [1–12]. In fact, some observers contend that the majority of lesions diagnosed as visual pathway gliomas are not tumors, but rather hamartomatous masses [13].

Visual cortex activation was a frequent topic of initial functional magnetic resonance imaging (fMRI) investigations,1,2 and since then, fMRI has had a great impact on visual neuroscience as it relates to the human brain. The reasons for this are severalfold.
