Two dissociable updating processes in working memory
Similarly, networks of neurons can fire in relative synchrony or in relative disarray; this coherence affects the strength of the signals received by downstream neurons.
Finally, inside each and every neuron is a leaky integrator circuit, composed of a variety of ion channels and continuously fluctuating membrane potentials.
Historically, emotion and cognition have been viewed as largely separate.
Many cognitive processes are thought to involve sophisticated functions that may be unique to primates.“Executive functions” is an umbrella term for functions such as planning, working memory, inhibition, mental flexibility, as well as the initiation and monitoring of action.The impairment of executive functions in various clinical groups is a topic of much debate, as are recent attempts to formulate the corresponding intervention and rehabilitation regimes of these dysfunctions.Averaging techniques allow specific neural responses to be extracted; these responses are known as Event-Related Potentials (ERPs) and represent the summation of postsynaptic potentials between individual neurons (Woodman & Luck, 2003).ERP research has identified several wave components, where the term component refers to the sequentially activated processes that are then measured on the scalp as distinct positive and negative wave patterns (Donchin, Ritter & Mc Callum, 1978).

Our primary tool for this exploration is a flexible cognitive cycle employed by the IDA computational model and hypothesized to be a basic element of human cognitive processing.
