3. On Intelligence Jeff Hawkins –Founder, Palm Computing: Palm Pilot –Founder, Handspring: Treo –Founder: Numenta Redwood Neuroscience Institute Redwood Center for Theoretical Neuroscience at UCBerkley –Published On Intelligence in 2004

4. One Function for All? Vernon Mountcastle, Johns Hopkins “An Organizing Principle for Cerebral Functions”, 1978 –The various regions of the cortex for different senses all look the same … –Mountcastle proposed that all cortex regions implement the same algorithm. –Vision, hearing, sensing … all the same thing from the perspective of neural computation

5. Brains vs. Computers BrainsComputers very slowfast highly parallelgenerally sequential highly redundantgenerally singular composed of layers of neurons composed of storage and processing units

6. Information flows both ways Spatial and temporal patterns from retinas

7. What you think you see.

8. What your eyes are actually focusing on. Saccades and fixations ~3/second

9. What you think you see.

10. What your eyes are actually receiving. Distortions amplify what your eyes are fixated on Shifts in fixation do not simply shift the image

11. IT cells respond to specific object types in fov: i.e. a human face V1 cells respond to specific features: i.e. a line slanted at 30degrees

12. When inputs don’t match predictions (at any layer), the discrepancy is quickly noticed. Feedback signals are predictions about what we expect to happen next

18. Feedback signals are spread very broadly across upper layer
