Thalamic patients performed significantly worse on multiple neuropsychological tests compared to comparison patients.

(A) Overlap of lesions in patients with thalamic lesions and comparison patients with cortical lesions. (B) Neuropsychological test scores from patients with thalamic lesions and comparison …

Figure 2 with 1 supplement
Lesions associated with impaired performance on tasks across multiple cognitive domains.

(A) Left panel: overlap of lesion masks from subjects with impaired test performance on each task. Impaired task performance defined as z < −1.645 (95 percentile in z distribution). Right panel: …

Lesion sites of all thalamic patients.
Figure 3 with 1 supplement
Comparing the degree of average behavioral impairment (x axis) and multi-domain behavioral impairment (y axis) between thalamus patients and comparison patients.

More negative average impairment score represents more severe behavioral impairment. Higher multi-domain impairment score indicate more cognitive domains were affected. Individual dots represent …

Lesions to thalamic regions with strong hub properties are associated with behavioral impairment across cognitive domains.

(A) Thalamic lesion sites associated with multi-domain impairment are located in the anterior-medio-dorsal thalamus. (B) Right panel: left medial and anterior thalamus is associated with prominent …

Comparison lesions with strong hub properties are associated with behavioral impairment across cognitive domains.

(A) Comparison lesion sites associated with multi-domain impairment are located in the lateral frontal and posterior parietal regions. (B) Frontal and parietal regions exhibit strong connector hub …

The multi-domain lesion site does not show strong functional specificity.

(A) Voxel-wise kernel density plot of thalamocortical functional connectivity weight for each cortical network. Voxels in the multi-domain lesion site exhibit stronger functional connectivity with …

The multi-domain lesion site contains higher concentration of matrix cells.

(A) The anterior-medial thalamus had a relative higher expression of CALB1 (lower panel), which overlapped with the multi-domain lesion sites (upper panel). Color intensity in the lower panel …
