The reference is to a paper by Naomi Weisstein published in the late 1960's (I don't have the reference handy). She was discussing the question of how far the Hubel and Weisel feature detector concept could be pushed in explaining pattern recognition.

Now I believe I am familiar with the "grandmother" allusion. It refers to a concept which emerged from the Hubel-Weisel recording studies of neurons in the visual cortex of the cat. Later studies by others showed that neurons in a neighbouring region of the brain (the inferotemporal cortex?) were highly specific (fired only) to complex visual stimuli. The suggestion was made that in our cortex there may exist neurons which are so specifically tuned as to respond only to the stimulus of our grandmother's face. So the full allusion would be to a "grandmother cell" (and I probably could even find out who first said it if I really wanted to). But yellow volkswagen? You've got me there. Are you sure you didn't mean "yellow submarine?" Stephen ----------------------------------------------------------------- Stephen L.
