  1. Summary of Part 1: Basic Mechanisms

  2. Micro vs Macro scales Micro = basic mechanisms common across brain areas Macro = differentiation, organization, and interaction of areas Overview of macro scale before discussing cognitive abilities

  3. In Transition From Part I: Basic Mechanisms To Part II: Cognition http://www.youtube.com/watch?v=VaQ66lDZ-08&feature=related Spontaneous brain activity http://www.youtube.com/watch?v=FZ3401XVYww&feature=related miracle

  4. General Functions of Cortical Lobes (how is this determined?)‏

  5. Other (subcortical) Areas Hippocampus: rapid learning Thalamus: sensory input, attention Amygdala: emotion, fear/desire Basal Ganglia: motor control, gating of PFC Cerebellum: Coordinating movements Reward prediction system: dopamine release

  6. Hierarchical sequencesof transformations Motor 1 Frontal Motor Movements Supp. Motor Frontal Motor Plan PFC Frontal Plan Ant. Pole Temporal Object Meaning Inferior Temporal Objects V4 Occipital Shapes V1/V2 Occipital lines+colors Visual input Retina

  7. More processing for motor output Cortical Hierarchy Meaning Amount of processing Physical Details Input

  8. Multiple Interacting Pathways Maintaining Abstract Information (plans, sensory info, etc) Movement Spatial Processing Touch Visual Object Recognition AuditionAbstract Semantics Early Vision
