The Anterior Cingulate Gyrus Returns To The Cluster Discharge Activity During The Object Recognition And Memory Process

The present study is to explore the role of anterior cingulate cortex (ACC) in object recognition memory, by using vivo multi-channel neuronal recording technique to record the neuronal activities and local field potentials (LFPs) in ACC area when rats were performing object recognition tasks in bow-tie maze. The results showed that after a period of training, most of the rats clearly demonstrated a preference for new different objects, there were significant differences in recognition index of repeated showing the object in six times. Second experiment found that the rat's anterior cingulate cortex neuronal firing frequency in the old and new objects with the characteristic differences, while the local field potential showing the event correlation. Studies have shown that the anterior cingulate plays a vital role in object recognition tasks. The results suggested that the repeated times of exhibiting would help increase the memory, also proved the the dual-process theory.
