Optimal degrees of synaptic connectivity

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.
