Different Brodmann Atlas in DPABI and REST

Submitted by yaosir on Fri, 08/29/2014 - 13:57

Dear experts,

I found that Brodmann Atlas was used in DPABI Viewer and REST Slice Viewer. In REST, there are 48 areas in the Brodmann Atlas, whereas there are only 41 areas in DPABI. I wonder if there are any other differences between these two atlas? And which one is recommanded?

Thanks in advance!

Hi Vincent,

Please post a figure to show that.

Dear Dr. Yan,

As shown in the upper figure, coordinate (30,0,16) locates in BA 48 area in REST, but it locates in BA 41 area in DPABI in the middle figure.  Additionally, I found that there were only 41 areas in BA atlas in DPABI in the bottom fugure.

The BA 41 and 42 seems wrong in MRIcro. Below was a slide in my “Functional Neuroanatomy” course for graduate students in Key Lab of BNU. The left two slices were Heschl’s gyrus in AAL but BA 48. And the right two slices were posterior temporal gyrus in AAL but BA 41 and 42 in MRIcro.

 

Anyway, the coordinates you mentioned (30,0,16) is neither BA 41. It should be near the insula (namely BA 48 in MRIcro). Please check. If you are correct, there may be something wrong in the coordinate system in DPABI or REST.

Hi,

I think Dr. Zang is correct! Please be aware of this issue.

Sandy mentioned there is a bug and he will fix soon. Hi Sandy, could you post your comment here?

Hi Dr. Zang,

We can not see the pictures you replied by email.

Actually, If any pictures are needed in the comments, please go to the website and click this button.

And if you want the pictures displayed in the emails through mailing list, the follows should be done:

Add http://rfmri.org at the beginning of the URL:

You can do it when uploading the picture, or revise it later by right click -> Image Properties.

I can make the attachments to be pushed to the website from email replies, but that will cost me 3 days of research and programming. I decided it didn't deserve the cost. Probably will do that in the long future.

Thanks,

Chao-Gan

Dear Dr. Zhang and Dr. Yan,

Thank you for helpful replies. Looking forward the revised DPABI!

Dear experts,

I am encountering some new problems about Brodmann atlas in DPABI. Specifically, there is a cluster remaining in the statistical map, and the peak MNI coordinate is (-39,6,30). Using DPABI viewer, I found majority voxels of this cluster are corresponding to BA 44.

However, no voxels belong to BA 44 as shown in CI report, which is as follows:

Number of voxels: 216
Peak MNI coordinate: -39   6  30
Peak MNI coordinate region:  // Left Cerebrum // Frontal Lobe // Inferior Frontal Gyrus // White Matter // undefined // Precentral_L (aal)
Peak intensity: 4.583
# voxels structure
  216 --TOTAL # VOXELS--
  216 Frontal Lobe
  216 Left Cerebrum
  152 White Matter
  110 Precentral_L (aal)
   84 Inferior Frontal Gyrus
   81 Middle Frontal Gyrus
   60 Gray Matter
   50 Frontal_Inf_Oper_L (aal)
   42 Sub-Gyral
   39 brodmann area 9
   31 Frontal_Mid_L (aal)
   16 brodmann area 8
   10 Frontal_Inf_Tri_L (aal)
    9 Precentral Gyrus
    5 brodmann area 6
 
 
    It is just an example about my doubts. Another typical one is that the insula is in BA 48 in DPABI viewer, but it usually belongs to BA 13 in CI report deponding on XjViewer. I have examined this region in some papers. Insula is usually located in BA 13, but no paper reported that insula is located in BA 48. Is there something wrong in DPABI viewer?
 
Thanks in advance,
 
Vincent

Hi Vincent,

DPABI is using MRIcroN's brodmann.nii. Seems there are some issues with that atlas file. I have a collegure is emailling Dr. Chris Rorden, hope we can get some response.
