=== 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'' |
