猴子前额叶皮质和丘脑内侧背侧核的神经细胞表现出与延迟反应测试表现相关的放电频率的变化。大多数细胞在线索呈现期间或随后的延迟开始时增加放电；在整个延迟过程中，一些细胞中存在高于发作间期的尖峰放电。这些变化被解释为额丘脑回路在涉及短期记忆的注意力过程中发挥作用的提示性证据
Nerve cells in the monkey's prefrontal cortex and nucleus medialis dorsalis of the thalamus show changes of firing frequency associated with the performance of a delayed response test. Most cells increase firing during the cue presentation period or at the beginning of the ensuing delay; spike discharge higher than that in intertrial periods is present in some cells throughout the delay. These changes are interpreted as suggestive evidence of a role of frontothalamic circuits in the attentive process involved in short-term memory
