For example, after intracerebral blood injection in the rat, activated microglia were noted by 4 hours and that activation lasted for at least 4 weeks [ 93].
The first time the device went on for five seconds, and the second activation lasted for 23 seconds.
The spontaneous Smad 3 activation lasted for at least 2 hours, that of p38 lasted for at least 4 hours (Figure S 1).
The somatosensory discrimination activation lasted around 5 minutes.
This is closely followed by another wave of transcriptional activation lasting about 1 h and diminishing before stage 10.
However, most of the tests showed an under-estimated duration before fire suppression (discrepancy up to 26 s for a spray activation lasting 73 s), which demonstrates the need for model improvement.
MIF induces a rapid and transient ERK activation (lasts less than 90 minutes) [2], as well as a sustained ERK activation (lasts up to 24 hours) [3].
Thus if the activation lasts longer than the proper pulse τ θ, the system can recover its primary state.
The run-to-turn transition in both cases was preceded by a positive lobe in the probability of optogenetic activation lasting ∼2 s.
There is considerable evidence that even a brief sensory event may cause an entire series of brain activations, lasting way beyond the duration of the stimulus.
