PMID-18701678[0] Reward facilitates tactile judgments and modulates hemodynamic responses in human primary somatosensory cortex.
- "Remarkably, primary somatosensory cortex contralateral to the judged hand was reactivated at the point of reward delivery, despite the absence of concurrent somatosensory input at that time point."
- hence, it is probably rostral to the central sulcus too.
- the same as http://m8ta.com/index.pl?pid=630
- rewarded humans with $
- people had to discriminate the frequency of electrical stimulation to their left/right index fingers. i guess a vibrator would have been hard in the magnet of an MRI machine.
- reward cue was visually instructed.
- reference Janaina's paper. http://www.jneurosci.org/cgi/content/full/27/39/10608
