A 2026 rat study estimated that adult hippocampal neurogenesis added 670,000 dentate gyrus granule neurons from 2 to 18 months of age, but the total dentate gyrus population grew by only 385,000 cells because older developmentally born neurons were also being lost.1 The result makes adult neurogenesis look numerically larger than the usual “tiny trickle” …
A 2026 iScience study found that 45 days of clomipramine improved spatial, working, and reference memory in female APP/PS1 Alzheimer’s-model mice, apparently by blocking the E3 ubiquitin ligase Itch rather than by clearing amyloid plaques.1 Research Highlights 45-day clomipramine signal: 6-month female APP/PS1 mice received 25 mg/kg clomipramine every other day for 45 days, then …
Electroconvulsive therapy (ECT) has long been a controversial yet potent treatment for major depressive disorder (MDD), particularly in cases resistant to conventional therapies. Despite its effectiveness, the long-term cognitive effects of ECT have been a subject of intense debate. A recent meta-analysis offers new insights into these cognitive changes, shedding light on the nuances of …
Recent research reveals that combining fish oil and choline supplementation may have synergistic effects in boosting levels of brain docosahexaenoic acid (DHA) and memory enhancement in middle-aged mice. Key Facts: Combining fish oil and choline increased DHA levels in the brain more than either supplement alone in mice. The combination upregulated expression of key fatty …
Perhaps you’ve heard of the fictional story “Flowers for Algernon” about a laboratory mouse named Algernon. The mouse undergoes a nootropic-esque surgical procedure that dramatically amplifies his intelligence. The experiment is deemed so successful, that scientists decide to test the procedure in a human character named Charlie Gordon. Prior to the artificial enhancement of Charlie’s …
Ginkgo Biloba is a highly popular tree native to China that is often cultivated for use as both a food source and dietary supplement. Some fossil evidence suggests that Ginkgo has been utilized for over 270 million years. Various temples in China are noted to have very old Ginkgo trees, some of which were planted …
