Fear memory is critical for animals to trigger behavioural adaptive responses to potentially threatening stimuli, while too much or inappropriate fear may cause psychiatric problems. Numerous studies have shown that the amygdala, hippocampus and medial prefrontal cortex play important roles in Pavlovian fear conditioning. Recently, we showed that striatal neurons are required for the formation of the auditory fear memory when the unconditioned stimulus is weak. Here, we found that selective ablation of striatal neurons strongly diminished contextual fear conditioning irrespective of the intensity of footshock. Furthermore, contextual fear conditioning was strongly reduced in striatum-specific dopamine D1 receptor knockout mice. On the other hand, striatum-specific dopamine D2 receptor knockout mice showed freezing responses comparable to those of control mice. These results suggest that striatal D1 receptor is essential for contextual fear conditioning.
