The Geniculostritate pathway
Retina - LGN - V1, represents main visual pathway for humans
Techtopulvinar pathway
Retina - Superior Colliculus, associated with orienting reflux, main visual pathway for animals or fish
Ventral Pathway (Object Recognition)
Primary Visual Cortex - Inferior extradite - Inferior Temporal
Dorsal Pathway (Spatial Processing)
Visual Cortex - superior extradite - superior parietal
Parallel Processing
Multiple types of information are processed at the same time in different brain pathways
Non parallel processing
This means that the relationship between input and output is not a straight one to one line
What you take in may be different from actual context
Distributed processing
Cognitive task are not localized to one brain area, it takes multiple areas to understand
think multiple lobes working together
Think like directions for example
fMRI good and bad
Good spatial resolution, Nero vascular coding, and BOLD
Bad temporal resolution
Neurovascular coupling
Changes in neural activity produce changes in blood flow and brain metabolism
