Dr. Maria Wimber
The Center for Cognitive Neuroscience Colloquium Series welcomes Dr. Maria Wimber from the Univ. of Glasgow. Her talk is titled 'Memory reconstruction in the human brain' and will cover the following: Our memories are not static. Each attempt to recall a past event can adaptively change the underlying memory space. Here I discuss my lab's recent work investigating how the process of remembering unfolds in time, and how memory representations change over time. I present behavioural and electrophysiological (M/EEG) work that provides insight into how the mnemonic reconstruction process unfolds in time on a fast, sub-trial scale. Further, I show evidence from behavioural and fMRI studies in which we track the representational changes that occur in a memory trace on a much slower time scale, over longer delays and across repeated retrievals. These findings indicate that memory retrieval prioritizes certain mnemonic features over others, and that it interacts with time-dependent consolidation processes to adaptively modify memories.
