Extrastriate cortex
Karten in diesem Stapel (14)
- 1What is the lateral occipital cortex (LOC) responsible for in the extrastriate cortex?It receives input from V1 & V2 and is responsible for processing form.
- 2What is V4 responsible for in the extrastriate cortex?It receives input from V1 & V2 and is responsible for processing colour and form/orientation. It still has depth selective cells but in small quantities. No motion selective cells.
- 3What is V5/MT responsible for in the extrastriate cortex?It receives input from V1 & V2 and is responsible for processing motion. It still orientation/form selective cells but in small quantities. No colour selective cells.
- 4What is V3A/V7 responsible for in the extrastriate cortex?It receives input from V1 & V2 and is responsible for processing depth
- 5What are the ventral parts of extrastriate cortex responsible for?Perception (what objects are). It mainly comes form parvo pathway and through V4.
- 6What are the dorsal parts of extrastriate cortex responsible for?Spatial/action (where objects are and how to interact with them). It mainly comes from magno pathway and through V5/MT.
- 7What would happen if there is localized damage in the V4 area (this is in the ventral area of extrastriate cortex)?Achormatopsia (selective deficit in colour perception)
- 8What would happen if there is localized damage in the LOC area (this is in the ventral area of extrastriate cortex)?Form agnosia (selective deficit in object perception)
- 9What would happen if there is localized damage in the Fusiform face area (this is in the ventral area of extrastriate cortex)?Prosopagnosia (selective deficit in face perception)
- 10What would happen if there is localized damage in the V5/MT area (this is in the dorsal area of extrastriate cortex)?Akinestopsia (selective deficit in motion perception).
- 11What would happen if there is localized damage in the inferior parietal lobule area (this is in the dorsal area of extrastriate cortex)?Grasp related activity affected. Activated during eye movements
- 12What would happen if there is localized damage in the superior parietal lobule area (this is in the dorsal area of extrastriate cortex)?Reach related activity affected. Optic ataxia (selective deficit in hand movement control).
- 13What is Zeki's theory?Zeki believes that there are parallel pathways emanting from V1 & V2 and each is concerned with processing one attribute (form, colour, motion, depth). This is division of labour.
- 14What is Goodale & Zilner's theory?Goodale & Zilner believe there are 2 parallel pathways. The ventral (mainly parvo) pathway via V3, V4, V8 & LOC to IT cortex. These are concerned with "what" things are (colour and form). The dorsal pathway (mainly magno) pathway vio V5/MT, V3A & V7 to PP cortex is concerned with where and how (motion & 3D spacial processing)
