摘要

Spontaneous firing activity in dissociated rat cortical tissue cultured in vitro shows highly stable firing rates over periods of hours. Recently, it was sho'wn that a short period of low-frequency electrical stimulation induces significant and lasting changes in these firing rates. Now, it is shown that these changes also occur in the presence of the synaptic plasticity blocker KN93 in the culture medium. Apparently, the changes in firing rates after a short period of low-frequency stimulation do not depend on CaMK-Ⅱ mediated synaptic plasticity.
