A Model for Delay Activity Without Recurrent Excitation
... Delay activity (DA) is the increased firing rate with respect to baseline of a population of neurons, which is caused by a stimulus and which persists once the stimulus is removed. DA is believed to be the neural substrate of working memory and therefore a good model of DA is of prime importance for ...

Neural correlates of consciousness
The neural correlates of consciousness (NCC) constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept. Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena. The set should be minimal because, under the assumption that the brain is sufficient to give rise to any given conscious experience, the question is which of its components is necessary to produce it.
