1. PERCEPTION (… start @ Hierarchical Organization)
Principles of Perception
o Hierarchical Organization
Moving from lower-order sensory neurons -> higher-order sensory
neurons
Receptive fields get larger
Sensory features get more complex
Sensory features get more specific
Processing proceed in serial (sequential), parallel
(simultaneously), and its recurrent (loops)
Multisensory integration increases
o Hierarchy in Visual System
Primary Visual Cortex
Striate cortex/ V1
Secondary Visual Cortex
Extrastriate cortex/ V2, V3, V4, V5/MT
Tertiary Visual Cortex
Visual association cortex/ MST, LIP, etc.
Multimodal association Cortex
VIP, etc.
o Hierarchy Auditory System
Primary Auditory Cortex
A1/ Core
Secondary Auditory Cortex
A2/ Belt
Tertiary Auditory Cortex
Auditory association cortex/ Parabelt (PB), etc.
Multimodal Association
T2/ T3, PP, etc.
o Hierarchy Somatosensory System
Primary Somatosensory Cortex
S1/ BA 1, 2, 3
Secondary Somatosensory Cortex
S2/ PV
Tertiary Somatosensory Cortex
Somatosensory association cortex/ BA 5, MIP, AIP, etc.
Multimodal Association Cortex
