  • Data
  1. "Day 1" is a dataset already uploaded on Neurotycho (http://neurotycho.org/social-competition-task).
  2. "Day 2" is a dataset recorded on the next day of "Day1".
  3. "Sleep" condition is a dataset in "Sleep task" recorded on separate day.
Additional data will be uploaded soon.
  • Analysis
    • Time window
There are three time windows (size=500ms) prepared for each of two task events, "Show food" and "Food place".
  1. "Show food" + "Early": window was set between -750 ms and -249 ms around "Show food" event.
  2. "Show food" + "Middle": window was set between -250 ms and +249 ms around "Show food" event.
  3. "Show food" + "Late": window was set between +250 ms and +750 ms around "Show food" event.
  4. "Food place" + "Early": window was set between-1000 ms and -501 ms around "Food place" event.
  5. "Food place" + "Middle": window was set between -500 ms and -1 ms around "Food place" event. At some point during the window, monkey had already started reaching motion.
  6. "Food place" + "Late": window was set between 0 ms and + 499 ms around "Food place" event.
  • Frequency band power
Power spectrum of ECoG data at each time window was calculated by FFT.
  1. "Delta": power spectrum at 2 Hz.
  2. "Theta": power spectrum summated within 4 Hz and 6 Hz.
  3. "Alpha": power spectrum summated within 8 Hz and 12 Hz.
  4. "Beta": power spectrum summated within 14 Hz and 28 Hz.
  5. "Low Gamma": power spectrum summated within 30 Hz and 58 Hz except 50 Hz.
  6. "High Gamma": power spectrum summated within 60 Hz and 100 Hz.
  • Statistics test
MannWhitney test will be used for statistical comparison. Circles indicate locations of electrode.
After setting all parameters and when "Draw" button is pressed, statistical comparison will be made. Results will be shown by color by following rules.
  1. Red: condition 1 > condition 2 (p < 0.0001).
  2. Brown: condition 1 > condition 2 (p < 0.001).
  3. Light blue: condition 2 > condition 1 (p < 0.001).
  4. Blue: condition 2 > condition 1 (p < 0.0001).
