In the large-scale survey by Akhtar et al, 6,641 respondents provided descriptions of their first memory and their age when they encoded that memory, and they completed various memory judgments and ratings. The established view is that the distribution around mean age at encoding is truncated, with very few or no memories dating to the preverbal period, that is, below about two years of age. However, Akhtar et al found that 2,487 first memories (nearly 40% of the entire sample) dated to an age at encoding of two years and younger, with 893 dating to one year and younger.

Panoz-Brown et al show that rats remember a stream of multiple episodes and the order in which they occur by engaging hippocampal-dependent episodic memory replay; rats remember the order of events using episodic memory replay and that replay is part of long-term memory, resistant to interference, and hippocampal dependent. The discovery could help advance the development of new drugs to treat Alzheimer’s disease. Image credit: Panoz-Brown et al, doi: 10.1016/j.cub.2018.04.006.

African grass rats (Arvicanthis niloticus) exposed to dim lights (DLD) for four weeks experienced, on average, a 30% decrease in the number of ‘dendritic spine’ connections in their brains, which are the tiny protrusions near the solid green line, a dendrite. These rats performed poorly on a maze-like task. Rats exposed to bright light (BLD), on the other hand, had many more of the dendritic connections and showed superior performance on the task.
