Introduction
Notes
Hypothesis
- DHA may potentiate synaptic plasticity (and cognition) via retrograde CB1 signaling.
- DHA activate the NMDA receptor and upregulate the release of glutamate. 1
- Hippocampal CA3 synapses facilitate synaptic plasticity, thus learning is enhanced. 2
- Induction of Long-Term Potentiation/Persistent synaptic plasticity (LTP). (Pathway)
- Synaptic activation of neurotrophic GABA(B) receptor by endocannabinoids (CB1) promote synaptic function and learning. (Is activity-dependent synaptogenesis dependent on BDNF?) 3 4
Model
- The Promoter: omega 3 (fish oil supplement) fatty acids
- DHA (docosahexaenoic acid) conjugate (in the hippocampus?) is docosahexaenoyl ethanolamide (DHEA).
- The Wet Blanket:
- Role: Protect the hippocampus and neurons from glutamate excitoxicity.
- CB1: A synaptogenic receptor? (most likely) 5
- The Vector:
- FAAH/anandamide hydrolysis of DHEA (a endocannabinoid like molecule)
- Activation of Ca2+ dependent BDNF via the TrkB pathway
