• Data

1. "Day 1" was uploaded on Neurotycho (http://neurotycho.org/social-competition-task).
2. "Day 2" was same experiment as "Day 1" except date of experiment. ( "Day 1" means 2010/08/03, "Day 2" means 2010/08/04.)
3. "Sleep" was different experiment as social-competition-task. It was an anesthesia experiment.

These data will be uploaded soon.

• Analysis

  • Time window

"Show food" or "Food place" and condition of "When?" decide time window for analysis.

1. "Show food" + "Early" means before start time at show food to monkeys (during -750 ms and -249 ms).
2. "Show food" + "Middle" means around start time at show food to monkeys (during -250 ms and +249 ms).
3. "Show food" + "Late" means after start time of show food to monkeys (during +250 ms and +750 ms).
4. "Food place" + "Early" means before time at putting a food on the table during (-1000 ms and -501 ms).
5. "Food place" + "Middle" means before time at putting a food on the table during (-500 ms and -1 ms). But the monkey started to move in this time window.
6. "Food place" + "Late" means after time at putting a food on the table (during 0 ms and + 499 ms).

• • Frequency

I used FFT to make power spectrum on each time windows.

1. "Delta" means a power spectrum (2 Hz).
2. "Theta" means power spectrum (summation of between 4 Hz and 6 Hz).
3. "Alpha" means power spectrum (summation of during 8 Hz and 12 Hz).
4. "Beta" means power spectrum (summation of during 14 Hz and 28 Hz).
5. "Low Gamma" means power spectrum (summation of during 30 Hz and 58 Hz without 50 Hz).
6. "High Gamma" means power spectrum (summation of during 60 Hz and 100 Hz).

• • Statistics test

I used MannWhitney test. Location of marks means location of electrodes.

1. Red mark means condition 1 > condition 2 (p < 0.0001).
2. Orange mark means condition 1 > condition 2 (p < 0.001).
3. Light blue mark means condition 2 > condition 1 (p < 0.001).
4. Blue mark means condition 2 > condition 1 (p < 0.0001).
