Ciao Giovanna,

Many works using ICA studied the brain funcitonal connnectivity to find cerebellar components of classical networks, and suggest a link between the DMN and the Lobule IX (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2742620/). You may want to check the distance from your cluster.

Anyway, the interpretation of functional associations between cortical DMN and the cerebellum depends on the method, and on the experimental paradigm.

I'm less sure about the putamen. Basal Ganglia network is usually anti-correlated with the DMN, and the disruption of this anti-correlation seems to be associated with clinical synptoms (https://www.ncbi.nlm.nih.gov/pubmed/23400553).

Anyway, disrupted anti-correlation is something very common across pathologies. And most of the times we don't know what does it mean.

Hope this helps,

Simone

Dear Giovanna,

On literature review about DMN, most of the literatures do not include Lentiform nucleus and cerebellum.  They mainly involve during motor planning and learning.

Hi Giovanna,

Buckner (2012) provides a solid reference for anatomical boundaries of the default mode network (DMN; see Figs 4 and 5). Though things may change (e.g., improved techniques for imaging small structures), the current conceptualization of the DMN typically does not include cerebellum or components of the basal ganglia.

Buckner, R. L. (2012). The serendipitous discovery of the brain's default network. Neuroimage, 62(2), 1137-1145.

Good luck,

Steph

Hi Giovanna.

Cerebellum is considered as implicit memory,is correlated with inner language ,so DMN 

include it,if you close eyes .

good luck
