“…The very first studies in neuroscience demonstrated analytically that the mean-field approximation was valid for homogenous neural networks when the numbers of neurons tend to infinity (Amari, 1972;Amari et al, 1977). Ever since, numerous studies have analysed the mean-field in neural networks under diverse conditions such as in finite neural networks (Mattia and Del Giduice, 2002;Touboul and Ermentrout, 2011), with different connectivity patterns (Cessac and Vieville, 2013;Moynot and Samuelides, 2002;Samuelides and Cessac, 2007;Brunel and hakim, 1999;Cessac, 1995), using different single-cell neuronal models (Abbot and Vreeswijk, 1993;Cessac, 2008;Treves, 1993)), using realistic parameter regimes (Grabska-Barwinska and Latham, 2013), or as a function of time (Molgedey et al, 2013;Moynot and Samuelides, 2002), the so-called dynamic mean-field approaches.…”
