在大脑中，内部注意探照灯由丘脑的网状复合体（包括密切相关的膝状体周围核）控制，探照灯的表达是在丘脑神经元的子集中产生快速放电。由注意力探照灯产生的连接是由可快速改变的突触（这里称之为马尔斯堡突触）介导的，特别是由作用于它们的快速爆发介导的。Malsburg突触的激活被设想为产生瞬时细胞组装，包括暂时联合神经层级中不同水平的神经元的垂直组装。
In the brain, the internal attentional searchlight is controlled by the reticular complex of the thalamus (including the closely related perigeniculate nucleus), and the expression of the searchlight is the production of rapid bursts of firing in a subset of thalamic neurons. The conjunctions produced by the attentional searchlight are mediated by rapidly modifiable synapses, here called Malsburg synapses, and especially by rapid bursts acting on them. The activation of Malsburg synapses is envisaged as producing transient cell assemblies, including vertical ones that temporarily unite neurons at different levels in the neural hierarchy.
