🧪 Overview
Migratory animals maintain spatial memories across generations through epigenetic modifications. Reactivating these pathways could restore lost spatial memories in Alzheimer's patients by reinstating dormant memory traces.

IF DNMT3A is selectively overexpressed in the dorsal hippocampus of 5xFAD transgenic mice via bilateral AAV-mediated gene delivery at 6 months of age, THEN these mice will demonstrate a ≥25% improvement in spatial reference memory retention during probe trial testing in the Morris water maze within
Predicted outcome: 25% improvement in spatial memory retention (time in target quadrant during probe trial)
Falsification: No significant difference in spatial memory retention between DNMT3A-overexpressing and control 5xFAD mice (p > 0.05), or spatial memory performance worsens in the DNMT3A group

IF CBP is pharmacologically activated in the entorhinal cortex of APP/PS1 mice using a CBP-activating small molecule (CC-10175031, 10mg/kg/day i.p. for 3 weeks), THEN place cell stability and spatial coding precision in layer II medial entorhinal grid cells will increase by ≥30% within 6 weeks, as m
Predicted outcome: 30% increase in place cell stability (spatial information content) and grid cell spatial coherence scores
Falsification: No increase in grid cell spatial coding precision or grid cell firing patterns become more irregular (grid score decreases by >20%) following CBP activation
