(+)-JRT, a de novo synthesized LSD analogue (two-atom transposition), retains potent neuroplasticity-promoting effects while markedly reducing hallucinogenic liability. It offers a path toward treating depression, addiction, and cognition deficits in patients (e.g., SCZ, psychosis family history) for whom classical psychedelics are contraindicated.
- **Mechanism:** promotes cortical spinogenesis / dendritic growth (same pathway as LSD)
- **Selectivity:** improved receptor pharmacology; does *not* amplify psychosis-associated behavioral or gene-expression signatures
- **Behavioral readouts:** antidepressant- and cognition-relevant assay effects
- **Design principle:** minimal structural edit → "nonhallucinogenic psychoplastogen" class

Neuroscientists have identified a novel mechanism called behavioral timescale synaptic plasticity (BTSP) that allows the brain to learn from single experiences. While traditional Hebbian plasticity requires repeated stimulation over time, BTSP operates on a scale of several seconds, enabling immediate memory formation in the hippocampus. This process is driven by dendritic plateau potentials that can strengthen synapses across a wider temporal window than previously understood.
Main topics:
* Discovery of behavioral timescale synaptic plasticity (BTSP)
* Comparison between Hebbian learning and single-trial learning
* The role of dendritic plateau potentials in memory formation
* How BTSP helps solve the credit assignment problem in neuroscience
* Potential implications for artificial intelligence models

This study explores the role of the Wnt pathway in regulating dendritic spine morphology and synaptic function. The authors found that activation of the Wnt pathway leads to the formation of new spines and enhances synaptic strength. Their findings suggest a novel mechanism by which the Wnt pathway influences synaptic plasticity and cognitive function.
