Table 1 Anatomical criteria for volume measurements.
Brain region | Anatomical criteria for measurement |
|---|---|
Whole Brain | Base of the olfactory bulb to last slice containing cortex |
Lateral ventricles | Defined from brain tissue by intense contrast of CSF |
Corpus striatum | Defined with reference to corpus callosum, external capsule, anterior comissure and lateral ventricles |
Midbrain | Defined with reference to dorsal hippocampal formation |
Hippocampus | Defined with reference to corpus callosum and external capsule |
Cerebellum | Defined with reference to 4th ventricle and brainstem as a guide |
