The configural association theory and the conflict resolution model propose that hippocampal function is involved in learning negative patterning tasks (A+, B+, AB-). The first theory suggests a critical role of the hippocampus in the formation of configural representations of compound stimuli, in which stimuli A and B are presented simultaneously. The second theory hypothesizes that the hippocampus is important for inhibiting the response to a stimulus that is in conflict with response tendencies. Although these theories propose different interpretations of the link between hippocampal function and non-spatial discrimination tasks, they both predict that the hippocampus is involved in the information processing of compound stimuli in negative patterning tasks. Recently, our electrophysiological approach has shown that the hippocampal theta power correlate with response inhibition in a negative patterning task, positive patterning, simultaneous/serial feature negative task. These findings provide strong support for the assumption of the conflict resolution model that the role of the hippocampus in learning is to inhibit responses to conflicting stimuli during non-spatial stimulus discrimination tasks.

海马θ节律在非空间歧视和联想学习任务中的作用。

形态联想理论和冲突解决模型表明，海马功能参与学习负构图任务（A +，B +，AB-）。第一个理论表明，海马在复合刺激的结构表征的形成中起着关键作用，其中，刺激A和B同时出现。第二种理论假设，海马对于抑制对与反应倾向冲突的刺激的反应很重要。尽管这些理论对海马功能与非空间歧视任务之间的联系提出了不同的解释，但它们都预言了海马体在负构图任务中参与了复合刺激的信息处理。最近，我们的电生理方法表明，在负构图任务，正构图，同时/串行特征负任务中，海马theta功率与反应抑制相关。这些发现为冲突解决模型的假设提供了有力的支持，即海马在学习中的作用是在非空间刺激识别任务中抑制对冲突刺激的反应。
