1 kwi 2017 · Vision is the primary sense in humans. There are approximately one million axons in the optic nerve, constituting almost 40% of the total number of axons in all cranial nerves. The primary...
It examines vision, exploring the anatomy and physiology of the eye, the accessory structures and the visual pathways. It also considers some of the common pathologies that can affect the visual system. The first article in this series examined the nature of hearing and balance, and pathologies of the ear.
brain realizes visual perception and visual con-sciousness is correspondingly high. This chapter reviews our current state of knowledge about the systems-level functional anatomy of the hu-man visual system. The emphasis will be placed on the results of fMRI as a noninvasive imaging technique that combines structural informa-
1 lut 2004 · Here we review recent findings and methods employed to uncover the functional properties of the human visual cortex focusing on two themes: functional specialization and hierarchical processing.
: Recent innovative neurological tests are described that are able to show much more accurately the visual pathways, the process of vision, and the close relationships among sensory modalities. These tests also reveal the remarkable neuroplasticity of the human brain and disorders of connectivity that frequently involve visual function ...
The discovery and analysis of cortical visual areas are major accomplishments in visual neuroscience. The number, locations, and functional roles of these areas are important topics for continuing experimental studies of the human brain.
Over the past several decades there has been an explosion in scientific understanding of these complex pathways and net-works. Detailed knowledge of the anatomy of the visual system, in combination with skilled examination, allows precise localization of neuropathological processes.
