Age-related deficits on the radial maze and in fear conditioning: hippocampal processing and consolidation.
Young adult, middle-aged, and old male F-344 rats were assessed for their hippocampal ability. This was accomplished by examining the animals on two different paradigms, each incorporating a simultaneous measure of hippocampal-dependent and -independent processing. The animals were fear conditioned and then tested for retention of the conditioning context and tone. This was followed by an 8-arm...

the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...

15 صفحه اولOntogeny of contextual fear conditioning in rats: implications for consolidation, infantile amnesia, and hippocampal system function.
The authors present developmental evidence that contextual fear conditioning is supported by a short-term memory system that supports conditioning immediately after a shock and by a long-term memory system that supports contextual conditioning 24 hr after training. This is based on the finding that after 1 conditioning trial, rats 18 to 32 days old show the same amount of conditioned freezing w...
متن کاملSubstantia nigra role in fear conditioning consolidation.
The substantia nigra (SN) is known to be involved in the memorization of several conditioned responses. To investigate the role of the SN in fear conditioning consolidation this neural site was subjected to fully reversible tetrodotoxin (TTX) inactivation during consolidation in adult male Wistar rats which had undergone fear training to acoustic CS and context. TTX was stereotaxically administ...
