Lecture 8 Flashcards
What are the steps in the visual pathway?
- Light Energy
- Reception
- Transduction
- Transmission
- Perception
What 2 pathways are there in higher order visual processing?
- Ventral pathway
- Dorsal pathway
What are the 2 low order visual functions?
Sensory motor functions
Oculomotor functions
Where is the visual selective attention situated?
Parietal Cortex
Where are the visual memory/visual identification situated?
Inferotemporal cortex
What is Hemianopia?
Left/right vision is missing/impaired
What is retinopathy of prematurity?
Abnormal growth of eye blood vessels
What is ocular albinism?
Reduced pigment in eyes
What is Glaucoma?
Vitreous fluid builds up
What is retinitis Pigmentosa?
Impairments in rods/cones
What is Transduction?
Process of transducting sensory signals into neural signals
What two photoreceptors are there?
Rods and cones
Where does the transmission take place?
Optic Chiasm
Which HOVF are in the dorsal pathway?
Visual Selective Attention and Visual Spatial Attention
Which HOVF are in the ventral pathway?
Visual identification and Visual memory
