Age-dependent recovery. Here, the ‘recovery’ time, until all neurons are in a homeostatic regime again, is shown for different onsets of the lesion from 1 (1T) to 1000 morphogenetic time steps (1000T). Different sizes of the lesion (3, 11, 15, 17, 21, 25 and 31 neurons) were tested for the impact of the lesion size on the recovery time. Lesions larger than 15 neurons show an exponential increase in recovery time for later onsets. Stable networks do not completely compensate for lesions of that size within the maximum simulation time of 5000 morphogenetic time steps. Lesions equal or larger than 31 neurons are not fully compensated spontaneously independent of when the lesion sets in.
