Adult Neurogenesis in the Mammalian Brain: Significant Answers and Significant Questions (2011, background): “…granule cells, while making a small number of extremely potent, large mossy fiber connections with target CA3 pyramidal neurons, innervate tens of hilar basket interneurons, each of which in turn inhibits hundreds of mature granule cells in the dentate gyrus (Figure 4B) (Freund and Buzsá ki, 1996).”
Cation-chloride cotransporters and neuronal function. (2009, background): “Given that distinct GABAergic interneurons in various brain structures target anatomically distinct sites in the postsynaptic neurons (Freund and Buzsaki, 1996), it is not correct to assign a singular E GABA-A value to a given neuron—a more appropriate approach is to specify the E The…”

Reelin Regulates Neuronal Progenitor Migration in Intact and Epileptic Hippocampus (2007, background): “…not seen in the intact dentate, chain migration is typical of adult rodent subventricular zone (SVZ) neuroblasts that migrate to the olfactory bulb (Gates et al., 1995; Lois et al., 1996); as mentioned above, Reelin is necessary for neuroblasts to exit from the chains and disperse in the bulb…”
A Role for Hilar Cells in Pattern Separation in the Dentate Gyrus: A Computational Approach (2009, background): “As in other cortical networks, the GABAergic neurons of the dentate gyrus still defy complete characterization, and there is some intersection between groups (Scharfman, 1992, 1995, 1999; Freund and Buzsáki, 1996; Houser, 2007).”
Neural syntax: cell assemblies, synapsembles and readers (2010, unknown): “Given the diverse interneuron classes in the cortex (Freund and Buzsáki, 1996; Klausberger and Somogyi, 2008; Markram et al., 1998), it is expected that further research will identify novel mechanisms by which the different classes interact with each other and the principal cells to choreograph…”

Purkinje cells directly inhibit granule cells in specialized regions of the cerebellar cortex (2016, unknown): “This contrasts with other areas in the brain where principle neurons often recruit interneurons to regulate local excitability and gain (Bortone et al., 2014; Freund and Buzsá ki, 1996; Kato et al., 2013; Olsen et al., 2012; Sik et al., 1994).”
Neurophysiological and Computational Principles of Cortical Rhythms in Cognition (2010, background): “Entrainment involves unidirectional inhibitory-to-excitatory coupling, whereas in the hippocampus (305) and neocortex (85), interneurons and pyramidal cells are reciprocally connected.”
Characterization of neocortical principal cells and interneurons by network interactions and extracellular features. (2004, background): “One potential explanation for this low number is that not all inhibitory interneurons have short-duration action potentials (Freund and Buzsáki 1996).”
