Egyptian fruit bats (Rousettus aegyptiacus) track tree phenology and estimate fruit availability since the last visit; they exhibit future-oriented behavior and fly to specific protein-rich trees; when doing so, they pass and skip over many familiar sugar-rich trees; young bats must learn tree phenology through experience.

Daily cranberry supplementation (equivalent to 1 small cup of cranberries) over a 12-week period improves episodic memory performance and neural functioning,...

Deperrois et al. suggest that generating new, virtual sensory inputs via adversarial dreaming during REM sleep is essential for extracting semantic concepts, while replaying episodic memories via perturbed dreaming during NREM sleep improves the robustness of latent representations.

According to new research from the University of California, Davis, the entrainment of theta brain waves with a commercially available device not only...

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.
