Vision Flashcards
Occipital lobe
The primary centre for vision in the brain, shaping perceptions, guiding movements, and influencing behaviour
Calcarine sulcus
Houses much of primary visual cortex (V1) and divides the upper and lower halves of the visual field
Lingual gyrus
Contains parts of visual areas V2 and VP
Fusiform gyrus
Houses V4, is crucial for processing colour and complex shapes
V1 (striate cortex)
Serves as the first processing stage, receiving input from the lateral geniculate nucleus (LGN) of the thalamus and sending projections to all other occipital areas
V2
Connects to all other occipital regions and sends projections to all other occipital regions
Dorsal stream (parietal pathway)
Is involved in visually guided movement
LIP
Lateral intraparietal sulcus: Voluntary eye movement
AIP
Anterior intraparietal sulcus: Object-directed grasping
VIP
Ventral intraparietal sulcus: Visuomotor guidance
PRR
Parietal reach region: Visually guided reach
cIPS
Intraparietal sulcus: Object-directed action
Ventral stream (inferior temporal and STS pathways)
Is responsible for object recognition, processing colour, faces, and motion perception
LO
Lateral occipital: Object analysis
FFA
Fusiform face area: Face analysis
EBA
Extrastriate body area: Body analysis
FBA
Fusiform body area: Body analysis
STS
Superior temporal sulcus: Analysis of biological motion
STSp
Superior temporal sulcus (posterior): Moving-body analysis
PPA
Parahippocampal place area: Analysis of landmarks
V4
Specializes in colour perception, though some cells also process form
V5
An area critical for detecting movement
V3
Processes the shape of moving objects
Superior temporal sulcus (STS)
A multimodal region that integrates visual, auditory, and somatosensory input.
