=== Jerome Lettvin~~^1^~~ ===

Jerome Ysroael Lettvin (born Chicago, February 23, 1920) is a cognitive scientist and professor Emeritus of Electrical and Bioengineering and Communications Physiology at the Massachusetts Institute of Technology (MIT).

In 1967, Jerry debated [Deoxy:leary.htm Timothy Leary] about the merits of Wiki:LSD. Jerry hurled the timeless epithet "BULLSHIT!" at Leary, who was sitting in the lotus position near a candle. This in response to Leary (a licensed psychologist) characterizing the frank symptoms of [Deoxy:videx?q=temporal temporal lobe] epilepsy as a religious experience.

=== Jerome Lettvin's Unusual Experiments~~^1^~~ ===

;vertebrate axons exhibit sub-millisecond triphasic spikes;\

:''action potentials are found at nodes of Ranvier but absent in Remak fibers''

;a cut optic nerve trained to the olfactory lobe regrows, remapping the retina;\

:''senses appear to direct brain growth rather than the reverse''

;axonal stimulation backfires into the cell body;\

:''action potentials can travel from axons to the axon hillock and into the cell''

;stimulating the bulbo-reticular inhibitory system stops strychnine convulsions;\

:''reflexes have system-wide attenuation controls''

;axon pulse intervals can be separated into bands;\

:''some form of information is encoded in pulse intervals''

;color constancy derives from boundaries and vertices in motion over the retina;\

:''color is not related to wavelength''

;images stationary on the retina fade to invisible;\

:''movement is critical to vision''

;visible insects cause no nervous activity in a frog that sees a duck;\

:''attention obeys hierarchical rules''
