WebMar 29, 2011 · Synaptic weights follow very closely the number of connections in a group of neurons, saturating after only 20% of possible connections are formed between neurons in a group. When we examined the network topology of connectivity between neurons, we found that the neurons cluster into small world networks that are not scale-free, with less than ... WebDec 5, 2024 · PN responses to weak odors are boosted by the high degree of ORN–PN synaptic convergence in a glomerulus (∼25:1 in fly and ∼250:1 in mouse), as well as lateral excitatory interactions between PNs that are most functionally impactful in the weak stimulus regime.

Studies of brain network connectivity improved understanding on brain changes and adaptation in response to different pathologies. Synaptic plasticity, the ability of neurons to modify their connections, is involved in brain network remodeling following different types of brain damage (e.g., vascular, neurodegenerative, inflammatory). birth anime movie
