Cortical parcellations - Lobe mapping

Recommended Posts

Hi,

I’m a computer science student and I do my internship in a medical imaging laboratory where I work on machine learning methods for predicting brain age from T1 MRI. I learn every day different things about medical imaging, but I’m still very novice in this field.

I wanted to know if there is a simple way to match each anatomical parcellation label (Destrieux atlas https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937159/table/T1/?report=objectonly) with the correct lobe (frontal, temporal, limbic, parietal, occipital, insula or others). For example, I guess that S_temporal_inf matches with temporal lobe. I hope I will not be forced to make researches for each of the 74 parcellations, especially since I don’t know anything about it and I will not be capable of doing that.

My only prior knowledge is on the number of parcellations per lobe :

  • frontal : 19
  • temporal : 15
  • limbic : 8
  • parietal : 10
  • occipital : 10
  • insula : 8
  • others : 4

Any advice, or explanation may really help me in this task, because I don't know anything about it.

Thanks in advance for your help.

After having done researches, I precise regions for which I'm not sure or I have no idea

  • Paracentral lobule and sulcus
  • Subcentral gyrus (central operculum) and sulci
  • Lateral occipito-temporal gyrus (fusiform gyrus, O4-T4)
  • Horizontal ramus of the anterior segment of the lateral sulcus (or fissure)
  • Vertical ramus of the anterior segment of the lateral sulcus (or fissure)
  • Posterior ramus (or segment) of the lateral sulcus (or fissure)
  • Central sulcus (Rolando’s fissure)
  • Anterior transverse collateral sulcus
  • Posterior transverse collateral sulcus
  • Medial occipito-temporal sulcus (collateral sulcus) and lingual sulcus
  • Parieto-occipital sulcus (or fissure)
  • Pericallosal sulcus (S of corpus callosum)
  • Subparietal sulcus
