Table 1.

Largest eigenvalues λ_n and corresponding eigenvectors V ⁿ of the TDS matrix A representing the network of organ interactions shown in Fig. 1 for different physiologic states (Wake, REM, Light Sleep (LS) and Deep Sleep (DS)). Eigenvector components r_i(i = 1, …, 5) correspond to different organ systems: chin, respiration, heart, leg and eye, respectively.
