Summary:
- The article discusses a paradigm-shifting study from the Salk Institute suggesting that memory storage in the brain may be mediated by the size and shape of synapses rather than just the strength of electrical signals.
- Researchers utilized advanced 3D electron microscopy and computational modeling to discover that synaptic weight is determined by the physical volume of the synapse, which dictates the number of neurotransmitter receptors present.
- This finding challenges the long-held "Hebbian" model of synaptic plasticity and suggests that the brain’s storage capacity is significantly higher—perhaps an order of magnitude larger—than previously estimated by neuroscientists.
