@DegenRolf@Neuro_Skeptic Interesting, and odd. I don't think an N=1 experiment is enough for me in this case.2 replies 0 retweets 1 like -

@DegenRolf I know -- my point is that I understand the text in a way that limits this effect to the glans.@Neuro_Skeptic1 reply 0 retweets 1 like -

@fMRI_guy@DegenRolf I agree with that reading, though it doesn't explicitly say that prepuce has a high acuity. Someone must know though?!3 replies 0 retweets 1 like -

@DegenRolf@Neuro_Skeptic Interesting. In that case I'd expect increased cortical area in SII (which IIRC correlates w valence/relevance)1 reply 0 retweets 1 like -
