Striatal dopamine D1 receptor is essential for contextual fear conditioning
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 ...
متن کاملContextual fear conditioning in zebrafish.
Zebrafish are a genetically tractable vertebrate that hold considerable promise for elucidating the molecular basis of behavior. Although numerous recent advances have been made in the ability to precisely manipulate the zebrafish genome, much less is known about many aspects of learning and memory in adult fish. Here, we describe the development of a contextual fear conditioning paradigm using...
متن کاملSleep deprivation selectively impairs memory consolidation for contextual fear conditioning.
Many behavioral and electrophysiological studies in animals and humans have suggested that sleep and circadian rhythms influence memory consolidation. In rodents, hippocampus-dependent memory may be particularly sensitive to sleep deprivation after training, as spatial memory in the Morris water maze is impaired by rapid eye movement sleep deprivation following training. Spatial learning in the...
متن کاملEstrogen modulates sexually dimorphic contextual fear conditioning
The present study examined the role of ovarian steroids in contextual fear conditioning and hippocampal synaptic plasticity in female rats. In experiment 1, adult female rats were ovariectomized and submitted to contextual fear conditioning, a procedure in which rats received unsignaled footshock in a novel observation chamber; freezing behavior served as the measure of conditional fear. Ovarie...
متن کاملWorking memory and fear conditioning.
Previous studies of associative learning implicate higher-level cognitive processes in some forms of classical conditioning. An ongoing debate is concerned with the extent to which attention and awareness are necessary for trace but not delay eye-blink conditioning [Clark, R. E. & Squire, L. R. (1998) Science 280, 77-81; Lovibond, P. F. & Shanks, D. (2002) J. Exp. Psychol. Anim. Behav. Processe...
