• Data

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

• Analysis

  • Time window

1. 3 Show food + 1 Early means during start time of show food to monkeys -750 ms and -249 ms.
2. 3 Show food + 2 Middle means during start time of show food to monkeys -250 ms and +249 ms.
3. 3 Show food + 3 Late means during start time of show food to monkeys +250 ms and +750 ms.
4. 4 Food place + 1 Early means during time at putting a food on the table -1000 ms and -501 ms.
5. 4 Food place + 2 Middle means during time at putting a food on the table -500 ms and -1 ms.
6. 4 Food place + 1 Early means during time at putting a food on the table 0 ms and + 499 ms.

• • Frequency

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

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