Studies on neural mechanism of false recogniotion

Since the early study of Bartlett (1932) it has been recognized that memory is not a literal reproduction of the past, but is rather a reconstructive process in which bits and pieces of information from different sources are pulled together. Studies of memory would not be possible if memory was perfect. Its imperfections, however, are not restricted to simply forgetting; also included are distortions and illusions such as false recognition. This occurs when subjects incorrectly claim that a novel item has been encountered previously. Though, there have been an increasing number of studies examining the functional brain correlates of recognition memory using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), the neural basis of still not fully understood.

In our Laboratory we employ various neuroimaging techniques to study false recognition phenomenon.
