A, Bar graph of frequency (percentage of cases in which TDP-43 was observed) of pathological TDP-43 in ALS across salient brain areas. G indicates gyrus; SC, spinal cord. B, Whole-brain “heat” map of TDP-43 pathology in the central nervous system (CNS) of patients with ALS, based on the severity of TDP-43 deposits. Sagittal, lateral, coronal, and cross sections of CNS regions are shown. Colors reflect median severity scores across all cases calculated from grouped data (Table). The subjacent color scale depicts median scores from zero (green) to highest scores (red) in each region examined, and blue indicates unexamined regions. The numeral 1 indicates frontal lobe gray matter; 2, orbital gyrus gray matter; 3, motor cortex gray matter; 4, sensory gyrus gray matter; 5, temporal lobe gray matter; 6, parietal lobe gray matter; 7, occipital lobe gray matter; 8, cingulate gyrus gray matter; 9, midbrain; 10, pons; 11, medulla; 12, cervical spinal cord; 13, cerebellum gray matter; 14, cerebellum white matter; 15, dentate nucleus in the cerebellum; 16, substantia nigra; 17, frontal lobe white matter; 18, temporal lobe white matter; 19, basal ganglia; 20, amygdala; 21, cingulate gyrus white matter; 22, motor cortex white matter; 23, sensory cortex white matter; 24, parietal lobe white matter; 25, thalamus; 26, entorhinal cortex; 27, hippocampus (cornu ammonis 4 [CA4]–CA1/subiculum and dentate gyrus); and 28, entorhinal cortex white matter.

A, Lewy body–like inclusion (large arrow) in the substantia nigra; note the nucleus devoid of the endogenous TDP-43 staining (“cleared nucleus”) (small arrow) that is present in the affected neuron, but not in an unaffected neuron (asterisk). The arrowhead denotes neuromelanin granules. B, Fibrillar or skein-like formations in the substantia nigra (large arrow) and short dystrophic neurite (small arrow). C, Cleared neuronal nuclei coupled with cytoplasmic ringform inclusion (large arrow) in sensory cortex; note the unaffected neuron with normal endogenous nuclear staining (small arrow). D, Cleared nuclei coupled with cytoplasmic, granular, or diffuse staining (“pre-inclusions”) (large arrow) in Wernicke's area; note unaffected neuron (small arrow). E, Dentate nucleus of the cerebellum showing a Lewy body–like inclusion, coupled with a cleared nucleus (arrow). F, Motor neuron in primary motor cortex with cytoplasmic frayed inclusions (arrow) coupled with a cleared nucleus. G, Striatum showing neuronal intranuclear inclusion in a familial (superoxide dismutase-1–negative) case. H, White matter of cingulate gyrus showing 2 oligodendrocytes with cytoplasmic inclusions and cleared nuclei (arrows). I, Temporal cortex showing dystrophic neurites (long arrow) and neuronal cytoplasmic inclusions (small arrow). Figure Legend:
