Thalamocortical Connectivity and Microstructural Changes in Congenital and Late Blindness

Table 1

Overview of the cortical target masks and the corresponding thalamic nuclei.

Target mask	Cortical labels	Corresponding thalamic nuclei
Occipital	Pericalcarine; Cuneus; Lateral occipital; Lingual	Pulvinar; LGN; MGN; Lateral nucleus
Temporal	Middle temporal; Inferior temporal; Superior temporal; Transverse temporal; Fusiform; Temporal pole; Banks of superior temporal sulcus; Entorhinal; Parahippocampal	Pulvinar; MGN
Somatosensory/parietal-postcentral	Postcentral; Supramarginal; Superior parietal; Inferior parietal; Precuneus; Isthmus cingulate; Posterior cingulate	Lateral nucleus; Ventrolateral nucleus; Ventroposterior nucleus
Motor/precentral	Precentral; Caudal middle frontal; Paracentral	Ventrolateral nucleus; Ventroanterior nucleus
Frontal	Superior frontal; Frontal pole; Medial orbitofrontal; Lateral orbitofrontal; Rostral middle frontal; Rostral anterior cingulate; Pars opercularis; Pars orbitalis; Pars triangularis	Anterior nucleus; Mediodorsal nucleus

Cortical target masks defined by combining labels given by the Desikan-Killiany atlas. The last column shows the thalamic nuclei, corresponding to the respective cortical projection sites as defined from an anatomical atlas based on the normal healthy human brain [5]. LGN: lateral geniculate nuclei; MGN: medial geniculate nuclei.
