*; Data
# "Day 1" is a dataset already uploaded on Neurotycho (http://neurotycho.org/social-competition-task).
# "Day 2" is a dataset recorded on the next day of "Day1".
# "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".
# "Show food" + "Early": window was set between -400 ms and -1 ms around "Show food" event.
# "Show food" + "Middle": window was set between 0 ms and +399 ms around "Show food" event.
# "Show food" + "Late": window was set between +400 ms and +799 ms around "Show food" event.
# "Food place" + "Early": window was set between -400 ms and -1 ms around "Food place" event.
# "Food place" + "Middle": window was set between 0 ms and +399 ms around "Food place" event. At some point during the window, monkey had already started reaching motion.
# "Food place" + "Late": window was set between +400 ms and + 799 ms around "Food place" event.

:*; Frequency band power
:Power spectrum of ECoG data at each time window was calculated by FFT.
# "Delta": power spectrum at 2 Hz.
# "Theta": power spectrum summated within 4 Hz and 6 Hz.
# "Alpha": power spectrum summated within 8 Hz and 12 Hz.
# "Beta": power spectrum summated within 14 Hz and 28 Hz.
# "Low Gamma": power spectrum summated within 30 Hz and 58 Hz except 50 Hz.
# "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.
# Red: condition 1 > condition 2 (p < 0.0001).
# Brown: condition 1 > condition 2 (p < 0.001).
# Light blue: condition 2 > condition 1 (p < 0.001).
# Blue: condition 2 > condition 1 (p < 0.0001).

*; Guide (in Japanese)
:Please download BEGINS Guidebook from a link below.
:http://begins.neurotycho.org/guide_jp.pdf
:English guidebook will be released soon.
