Forebrain Processes in Normal Dreaming: An Integration of Neurophysiological, Neuropsychological and Neuroimaging Data

 

Regions:

1 and 2: ascending arousal systems;

3: subcortical and cortical limbic and paralimbic structures;

4: dorsolateral prefrontal executive association cortex;

5: motor initiation and control centers;

6: thalamocortical relay centers and thalamic subcortical circuitry;

7: primary motor cortex;

8: primary somatosensory cortex;

9: inferior parietal lobe;

10: primary visual cortex;

11: visual association cortex;

12: cerebellum.

 

This figure serves as a visual model for section 3.3.4.3 ("Activation-synthesis updated: An integrated model of REM sleep dreaming") and each element of the figure is explained in detail in that section.

 

Abbreviations: RAS, reticular activating system; PGO, ponto-geniculo-occipital waves; LGN, lateral geniculate nucleus; BA, Brodmann area. (From Hobson et al. 2000).
