Thalamus Intralaminar nuclei

One could view the situation also as an inability of the intralaminar nucleus of the thalamus to include in its habit routine-generating scan the information from the destroyed frontal region. This is probably the more useful if not accurate view, as opposed to the view that frontal lobe "information" has been destroyed, (back)... 

A global view of consciousness is that it is generated throughout the entire brain, as a result of synchronisation of relevant neural networks. Specific systems or regions—for example the cerebral cortex, brainstem reticular formation and thalamic nuclei—may be key anatomical integrators. Areas with the most widespread interconnections are pivotal, and on this basis the cortex and thalamus are more relevant than cerebellum and striatum for example. Frontal cortex for example connects with every other brain region, both in terms of input and output, with 80% of such connections accounted for by cortico-cortical connections. Thalamic intralaminar nuclei are, in conjunction with the reticular nucleus, reciprocally connected to all cortical areas. By contrast the cerebellum has very few output pathways and striatal-cortical input is (via the thalamus) confined to frontal lobe. 

Output targets of the substantia nigra include the following the thalamus, superior colliculus and the pedunculopontine nucleus (Beckstead 1979 Deniau and Chevalier 1992 Gerfen et al. 1982 Kita and Kitai 1987 Nakanishi et al. 1987b). Nigral inputs to the thalamus are directed to two main parts of the thalamus. The first are the set of nuclei, including the intralaminar nuclei, which project back to the striatum. The second...
