A team of Japanese neurologists and physiologists has found that momentarily suspending breathing in mice during a learning exercise can inhibit memory retention. In their study, reported in the journal Nature Communications, ...
The most detailed map ever made of the communication links between the hippocampus—the brain's memory control center—and the rest of the brain has been created by Australian scientists. And it may change how we think ...

A longstanding division exists between hippocampus-dependent and non-hippocampus dependent memory since only the latter can be acquired and retrieved in the absence of normal hippocampal functions. In agreement with the familiar ...
People often say that they never forget a face, but for some people, this claim might actually be true. So-called super recognisers are said to possess exceptional face recognition abilities, often remembering the faces of ...

Recognition memory is a subcategory of declarative memory Essentially, it is the ability to correctly remember something that has been encountered before. It can be thought of as a matching process, comparing content in the environment with the content stored in memory. Recognition occurs if the environmental content (i.e. the stimulus) matches the memory content. (If there is a mismatch then recognition does not occur.)
Recognition memory can be subdivided into two components: recollection and familiarity, sometimes referred to as "remembering" and "knowing", respectively. Recollection involves remembering in detail a particular stimulus, including the context in which it was previously experienced. In contrast, familiarity only requires knowledge of the stimulus’s features – the basic realization that one has encountered the stimulus before. Thus, the fundamental distinction between the two processes is that recollection is context dependent whereas familiarity is context-independent. Another distinction is that familiarity is generally an unconscious or automatic process whereas recollection is conscious and effortful.
