Document Summary
Different levels of categorization activate different brain networks. Significant activity levels from fusiform cortex for subordinate categorization over basic. (specific vs. prototypical, basic level) Fusiform face area - processing relevant fine visual detail; activates during facial recognition. Are there cells that represent conceptual information? (preferentially) (ex, if you heard the sound of your heart, would a cell respond to that more than another cell that wasn"t preferentially responsive to that stimuli?) Hubel & weisel, looking at lower level cells, combining them with higher level cells to process more complex shapes and images. There may be areas in the brain that are selectively responsive to something, but not to other things. Can be applied to general knowledge (gnostic cells) Lettvin; grandmother cells (if you lost your grandmother cells, you wouldn"t be able to recognize your grandmother anymore; you"d lose everything associated to your grandmother) (used as an example regarding how concepts are perceived by cells)
