Crick proposed that the thalamic reticular complex implements an internal attentional 'searchlight' by producing rapid bursts in subsets of thalamic neurons that, via rapidly modifiable (Malsburg) synapses, transiently bind cell assemblies across cortical hierarchical levels.

It is suggested that in the brain the internal attentional searchlight, proposed by Treisman and others, is controlled by the reticular complex of the thalamus (including the closely related perigeniculate nucleus) and that the expression of the searchlight is the production of rapid bursts of firing in a subset of thalamic neurons.
