Synesthesia

synesthesia

stimulation of one sensory pathways lead to automatic involuntary experiences in a second pathway

most common forms

numbers, music, month based, taste

synesthetic association at a central level of processing

post information from the two eyes has been combined

brain region that interact with those that synthesize color

involved in structure from motion computations

classic stroop task

name the color of the ink, don’t say the letters

search task

pop out searches, attention needed to bind numbers and color

synesthetic colors are evoked at

perceptual stage of processing

the stronger the activation

the stronger the behavioral benefit

cross activation

adjacent in brain legions, due to failure of pruning during development

disinhibited cortical feedback

reduction in the amount of inhibition along feedback pathways, can be induced by drugs
