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'' === Reference === #Wikipedia:Jerome_Lettvin
