Time harvested

Lesions observed

B2

1 x 74.5

24 h

Tear causing repositioning of part of the caudate-putamen into the insula.

B3

1 x 74.5

24 h

Blood in dorsal 3rd and lateral ventricles as well as choroid plexus.

B4

1 x 74.5

24 h

Blood in dorsal 3rd and lateral ventricles.

B1

3 x 74.5

24 h

Blood in dorsal 3rd ventricle.

B5

3 x 74.5

24 h

Blood in aqueduct, dorsal 3rd and lateral ventricles; vascular disruption affecting external capsule and CA1 field; blood in the adjacent parenchymal tissue.

542

3 x 74.5

6 months

Tear spanning the perirhinal cortex, external capsule, hippocampal CA1 region and dentate gyrus resulting in tissue architectural abnormalities.

2

3 x 74.5

6 months

Lesion in the secondary auditory cortex expanding to the perirhinal region.

1

3 x 74.5

9 months

Tear at the surface of the secondary somatosensory cortex extending into the insular cortex; lesion involves repositioning of cortical layers; disruption of piriform cortex by the insertion of olfactory tubercle/lateral olfactory tract tissue.

590

3 x 74.5

10 months

Disruption of layers I, II and III in primary visual cortex; presence of ectopic neurons in layer I; lesion of hippocampal CA1.

591

3 x 74.5

10 months

Tear and repositioning of layers I, II and III in primary somatosensory cortex; ectopic neurons in layer I; disruption of parietal and somatosensory cortex and ventral/intermediate entorhinal cortex by the insertion of ectopic tissue.

595

3 x 74.5

10 months

Lesion in motor cortex altering the cortical architecture.

597

3 x 74.5

10 months

Displacement of amygdalohippocampal and posteromedial cortical amygdaloid nucleus tissue disrupting the ventral hippocampal CA1 field.
