Diverse Origins of Network Rhythms in Local Cortical Circuits
... (Lamsa et al., 2007). In stark contrast, local circuit synaptic excitation onto other excitatory neurons is rather sparse. Estimates from paired recordings give probabilities of finding coupled principal cell pairs (within a single lamina) from 1:100 to ~1:30 (Deuchars and Thomson, 1996; Thomson and ...
