Areas of the network of brain pdf brain included in the default mode network include the medial temporal lobe, the medial prefrontal cortex, and the posterior cingulate cortex, as well as the ventral precuneus and parts of the parietal cortex. Starting simple: receptors, pathways, and circuits 1) Neurons work using an integrate-and-fire action 2) Connections are either excitatory or inhibitory 3) Idealized neurons are used in artificial neural nets to model brain function 4) Neurons typically form two-way pathways, pdf providing the basis for re-entrant connectivity 5) The nervous system is formed into arrays or maps of neurons 6) Hebbian cell assemblies underlie the change from transient to stable, lasting connections.
