Another potential explanation for the effectiveness of 40-hertz stimulation is the discovery that interneurons —a subset of neurons— produce certain peptides in far greater quantities following treatment. William A. Haseltine, Forbes, 29 Feb. 2024 For example, in the human cortex, about 20 percent of the neurons — the ones called interneurons, which have inhibitory effects — migrate there from a center deeper down in the brain called the medial ganglionic eminence (MGE). Quanta Magazine, 9 Aug. 2017 An oversimplified organoid model for the cortex would be missing all those interneurons and would therefore be useless for studying how the developing brain balances its excitatory and inhibitory signals.

The Economist, 22 Feb. 2018 He and his colleague Molly Heyer therefore looked at the role of these micro-RNAs in regulating brain cells called parvalbumin interneurons, which are thought to be involved in schizophrenia. The Economist, 22 Feb. 2018 Yang and his team also found that SOM and PV interneurons had less activity. Beth Mole, Ars Technica, 27 June 2017 Around those pain-signaling neurons are several types of interneurons that precisely regulate and control pain signals. Beth Mole, Ars Technica, 27 June 2017
