If you stare at the center of your line of sight left of the center = left field, right of center = right field.

Thalamus has clusters of nuclei (clusters of cell bodies) involved in passing on info related to our senses: eg. Vision lateral geniculate nucleus (lgn), from here info goes to the primary visual cortex (called this because it makes connections in the visual pathway) Assumption that all visual info goes to the primary visual cortex first (secondary, tertiar(cid:455) (cid:895) Means the complexity of processing increases from v1 v2 v3.
