Learning and memory refers to the processes of acquiring, retaining and retrieving information in the central nervous system. It consists of forming stable long-term memories that include declarative (recall of events and facts) and nondeclarative (conditioning, skill learning) forms.
We examined how familiar faces are encoded in inferotemporal, perirhinal and temporal pole face patches, and found that relative response magnitude to familiar versus unfamiliar faces was not a stable indicator of familiarity in any patch.
Delay- and choice-related activities that are essential for working-memory performance drift during learning and stabilize only after several days of expert performance.
Children typically exhibit weaker memory than adults. Here, the authors report a developmental reversal-like phenomenon that children show better memory for attended but outdated information, suggesting underdeveloped memory selection in children.
Using a computational model to quantify difficulty in reconstructing images from compressed codes, Lin et al. show that reconstruction errors interface perception and memory by modulating how well images are encoded.
A mark test of self-recognition in mice reveals that self-responding ventral CA1 neurons underlie mirror-induced self-directed behaviour and are shaped by social experience with conspecifics.
In mice, localized mutant APP expression in the CA3 hippocampal region leads to progressive network dysfunction and hippocampus-dependent memory deficits.
