Rostral-Caudal Absolute Differences

Details: Rostral-Caudal Data.sav<br>Data for producing Figures 1, 2 This dataset consists of spectral densities for 237 EEG records within discrete frequency bins for 19-channels. The 19 channels are: 1. Fp1<br>2. Fp2<br>3. F7<br>4. F3<br>5. Fz<br>6. F4<br>7. F8<br>8. T3<br>9. C3<br>10. Cz<br>11. C4<br>12. T4<br>13. T5<br>14. P3<br>15. Pz<br>16. P4<br>17. T6<br>18. O1<br>19. O2 The variable names are:<br>rc-absolute rostral-caudal difference<br>rl-absolute left-right difference<br>absz-absolute z-scores for rostral caudal used to select for 177 individuals<br>observed in Figures 1 and 2 (select zscores -1 -The next variables assume the general anatomy: c(x)w(y)<br>where x refers to channel number (1-19) and y refers to discrete frequency spectral density (FFT resolution 0.24 Hz) between 0 and 40 Hz. Thus: c1w56 refers to 13.44 (56*.24) Hz activity in Fp1<br>c11w89 refers to 21.36 (89*.24) Hz activity in C4…etc. -The next variables assume the general anatomy: rcw(y) where y is the absolute difference between Fp1 and O2<br>frequency spectral density (FFT resolution .24 Hz) between 0 and 40 Hz. Thus: rcw40 refers to 9.6 Hz (40*.24) absolute rostral (Fp1) caudal (O2)<br>difference. -The next variables assume the general anatomy rl(y) where y is the absolute difference between T3 and T4<br>frequency spectral density (FFT resolution .24 Hz) between 0 and 40 Hz. Thus: rl40 refers to 9.6 Hz (40*.24) absolute left (T3) right (T4)<br>difference.
