The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments". Retinal topography is maintained in the optic nerve, through the lateral geniculate to the visual cortex. This illustration shows the topographic organization of projections from occipitotemporal network to the neostriatum (caudate nucleus and putamen; red and blue/purple shaded areas), and the ventral striatum (VStr; gray shaded area). The auditory pathway is more complex than the visual and the olfactory pathways. The auditory pathway conveys the special sense of hearing.. Information travels from the receptors in the organ of Corti of the inner ear (cochlear hair cells) to the central nervous system, carried by the vestibulocochlear nerve (CN VIII).. The motor pathway, also called the pyramidal tract or the corticospinal tract, serves as the motor pathway for upper motor neuronal signals coming from the cerebral cortex and from primitive brainstem motor nuclei. human eye, in humans, specialized sense organ capable of receiving visual images, which are then carried to the brain.. Anatomy of the visual apparatus Structures auxiliary to the eye The orbit. 6).The nerve fibers of the retina, representing the axons of the ganglion cells, collect together at the optic disk before passing out of the eye through the orbital bones and into the brain via the optic nerve (the second cranial nerve). In this section, we will discuss the anatomy of the cells present in the retina. Simple Anatomy of the Retina The visual pathway describes the anatomical pathway by which electrical signals generated by the retina are sent to the brain (Fig. In this section, we will discuss the anatomy of the cells present in the retina. It is composed of a number of nuclei and is dependent on a range of functional areas. Visual Pathway and Visual Field Defects Consciousness. • Weber’s: CN III palsy and ptosis (drooping) ipsalateral (same side of body). fibers from the LGN makes it way to the visual cortex as optic radiations. It is developed from the optic vesicle, an outpocketing of the forebrain.The optic nerve can therefore be considered part of the central nervous system, and examination of the nerve enables an assessment of intracranial health.

The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments". The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. Within visual cortical areas, the perception of the stimuli and their location is passed along two streams, one ventral and one dorsal. Following the early visual pathway. As with the previously discussed nerve tracts, the sensory pathways of the trigeminal pathway each involve three successive neurons.

The Performing Arts pathway focuses on the direct creation of art and entertainment by the individual artist through mediums such as dance, theatre, and music. Visual stimuli from our surroundings are processed by an intricate system of interconnecting neurons, which begins with the optic nerve in the eye up to the visual processing center in our forebrain called the visual cortex. A glossary is included. Its disease will affect hearing as well as vision. Its disease will affect hearing as well as vision. This illustration shows the topographic organization of projections from occipitotemporal network to the neostriatum (caudate nucleus and putamen; red and blue/purple shaded areas), and the ventral striatum (VStr; gray shaded area). There also is a test for color deficiency and three short quizzes. • CN IV - Trochlear (Superior oblique muscle of the eye which rotates the eye down and out), [motor].
