Schematic depiction of two mesoscopic computational models capable of simulating oscillations in the alpha frequency range. Left: Cortico-thalamic model adapted from Freyer et al. (2011) involving the thalamus to generate alpha activity in a network of cortical excitatory neurons and inhibitory interneurons; Right: Cortico-cortical model adapted from Naruse et al. (2010) generating alpha activity without the thalamic control by interconnecting cortical macro-columns composed of excitatory pyramidal neurons accompanied by excitatory and inhibitory interneuron networks.
