Neuroanatomy Annotation Audit / 神经解剖标注审计
- Audit date: 2026-09-01
- Scope: all 10 existing annotated Atlas images from L01
- Method: identify view → identify landmarks → infer targets independently → consult PPT context → cross-view/reference verification → 1:1 render → re-open final output
- Result: 6 images corrected, 4 images reverified without material correction, 7 image sets
CONFIRMED, 3 image sets retain at least one visiblePROBABLElabel. - Confirmed PPT Annotation Conflicts: none. The corrected defects were in the previous Atlas endpoints/evidence, not confirmed errors in the course PPT. Slide 41 is recorded as non-target-specific because its visible arrows do not establish the four corpus-callosum subdivision endpoints.
Corrected
| Atlas | Correction | Reason |
|---|---|---|
| Corpus callosum midsagittal | Rostrum, genu, body, and thalamus endpoints recentered | The body could be read as pointing into the overlying cingulate/cortical region; endpoints now lie on the white callosal band or thalamic mass. |
| Diencephalon midsagittal | Corpus callosum and thalamus recentered | Anatomical landmark mismatch. |
| Basal nuclei components | Amygdaloid body and contextual thalamic mass recentered | Amygdala had landed on the caudate-tail stalk; thalamus was in an overlap zone. |
| Cortex lateral | Central and lateral sulci recentered | Endpoints had landed on adjacent tissue rather than within the sulcal grooves. |
| Cortex inferior | Midbrain and pons separated | Pons had landed on medulla; midbrain was too close to the pontine junction. |
| Hypothalamic nuclei | Paraventricular and infundibular endpoints refined | Centered within the depicted colored nuclear regions; infundibular boundary remains PROBABLE. |
Verified
- Thalamus–third ventricle coronal: thalamus, third ventricle, lateral ventricle, internal capsule.
- Internal-capsule axial: internal capsule, caudate, lentiform nucleus, thalamus.
- Cerebral-cortex medial: corpus callosum, cingulate gyrus, paracentral lobule, calcarine sulcus, parahippocampal gyrus.
- Basal-nuclei axial: caudate and thalamus confirmed; the low-resolution lentiform and internal-capsule boundaries remain
PROBABLE.
Needs Review
- Basal-nuclei components: contextual red mass labeled
PROBABLE: Thalamus; the PPT does not directly number it. - Basal-nuclei axial:
PROBABLElentiform nucleus and internal capsule because the source image is low resolution. - Hypothalamic-nuclei midsagittal:
PROBABLEinfundibular nucleus because its boundary is not fully separable.
These uncertainty labels do not block the confirmed content. No UNCERTAIN target was rendered as a formal arrow.

2026-09-08 · L02 新增图谱审计
- 新增 3 张 course-ppt 定位图：腹侧、背侧、正中矢状面，共 12 个新增箭头。
- Verified：腹侧的脑桥基底部、锥体、橄榄、大脑脚底；背侧的上丘、下丘、菱形窝、小脑；正中矢状面的中脑、脑桥、延髓、第四脑室。
- Corrected old labels：None；未更改 L01 图像或历史审计。
- 先识别切面、landmarks 和目标，再查看源 PPT 的标注和文字；新增箭头未直接复制 PPT 坐标。
- 每幅最终图已重新打开核对端点、邻近结构、双语图例、编号、遮挡与交叉，12 个整体结构标签均为 CONFIRMED。原课件细小核束箭头不在此认证范围。
- 哈希及坐标锁定在原始源像素；schema 中腹/背侧立体教学插图按 schematic-3d 登记，标题与证据明确腹/背方向。
- PPT Annotation Conflict：本轮未确认；CONFLICT-003–005 为课程文字/范围冲突。
- Verification source：REF-NCBI-BRAINSTEM-001，仅核对整体位置，不引用其中不一致的 roof/floor 英文括注。
- 新增 audit IDs：AUDIT-ATLAS-L02-BRAINSTEM-VENTRAL、AUDIT-ATLAS-L02-BRAINSTEM-DORSAL、AUDIT-ATLAS-L02-BRAINSTEM-SAGITTAL。
