Abstract(in English) | We hypothesize that neurons efficiently leverage their finite elements by changing their activities according to contexts. In order to investigate this switching mechanism, we proposed a context-dependent fear conditioning experiment and investigated learning-induced plasticity in rat auditory cortices. Only when background white noise was presented, rats received an electrical foot shock which was associated with a tone. After conditioning, neural activities in the auditory cortex changed only under the noise condition, while no significant change was observed in the silent condition. This result suggests that neural activities in the auditory cortex are changed according to contexts i.e., one activity for one context, and adapt to various contexts. |
