ABSTRACT
The synaptic and network theories of memory, which Cajal first advanced in Barcelona around 1890, have been firmly established and elaborated by three generations of neuroscientists. This article outlines a corollary model of memory in the cerebral cortex that derives from those theories and is empirically supported by modern functional methods. The model posits that the elementary unit of memory or knowledge is a network of neurons of the cerebral cortex associated by life experience according to Hebbian principles of synaptic modulation (a cognit). Networks or cognits of perceptual memory are hierarchically organized and distributed in posterior association cortex; those of executive memory, also hierarchically organized, are distributed in frontal association cortex. In the course of goal-directed behavior and language, perceptual and executive cognits engage in the perception-action cycle, the cybernetic cycle that dynamically links the cortical cognitive networks with the environment in the pursuit of goals,. The prefrontal cortex, at the summit of that cycle, and interacting with cortical and subcortical structures, guides behavior and language to their goals by means of its executive functions of planning, executive attention, working memory, decision-making, and inhibitory control
