Figure 4From: Theta-alpha cross-frequency synchronization facilitates working memory control – a modeling study Activity rates of the excitatory components of 4 Memory Units. To give a clear distinction, different colors are used for different Memory Units, and also the values of their activity rates are modified as E(t);E(t)+5;E(t)+10;E(t)+15 respectively. Parameter values are given by: (a) N=4;K 0=20;w 1=0.1;w 2=0. (b) N=4;K 0=20;w 1=0;w 2=0.02.Back to article page
