Defining the anthropocene.

abstract：:Paired-associate learning is often used to examine episodic memory in humans. Animal models include the recall of food-cache locations by scrub jays and sequential memory. Here we report a model in which rats encode, during successive sample trials, two paired associates (flavours of food and their spatial locations) ...
