Parvalbumin+ interneurons obey unique connectivity rules and establish a powerful lateral-inhibition microcircuit in dentate gyrus (2018, background): “Among the 25 possible disynaptic motifs, four types of motifs were significantly enriched above the chance level: (1) Gap junction connections between PV+ interneurons, (2) mutual inhibition motifs (PV+ interneuron–PV+ interneuron connections) combined with gap junction connections43, (3) convergenc”
Functional specificity of local synaptic connections in neocortical networks (2011, unknown): “The rate of connectivity was 0.19 (43 connections out of 222 potential connections assayed), in keeping with previous reports 6 , 8 , 10 .”
Search for computational modules in the C. elegans brain (2004, background): “Interestingly, an over-representation of bi-directionally connected doublets was also found for pyramidal neurons in mammalian neocortex [11-13].”

Laminar structure of spontaneous and sensory-evoked population activity in auditory cortex (2009, unknown): “…Schubert et al., 2007; Thomson and Lamy, 2007), the probability of PC-PC connections in L2/3 significantly decays over a spatial scale of $150 mm (Holmgren et al., 2003; Oswald and Reyes, 2008), providing a potential mechanism for local clustering of superficial spiking activity at this scale.”
Experience and Activity-Dependent Maturation of Perisomatic GABAergic Innervation in Primary Visual Cortex during a Postnatal Critical Period (2004, background): “In mature cortex, a single basket interneuron is estimated to innervate hundreds of pyramidal neurons (Holmgren et al., 2003), and each pyramidal neuron receives inputs from multiple basket cells (Somogyi et al., 1998; Holmgren et al., 2003).”
A Diffusive Homeostatic Signal Maintains Neural Heterogeneity and Responsiveness in Cortical Networks (2015, background): “Since connection probability falls off with spatial distance in cortical networks [18], we additionally simulated recurrent networks featuring such connectivity profiles.”
