Temporal Ordering of Dynamic Expression Data from Detailed Spatial Expression Maps

The segmentation clock drives oscillatory gene expression across the pre-somitic mesoderm (PSM). Dynamic Notch activity is key to this process. We use imaging and computational analyses to extract temporal dynamics from spatial expression data to demonstrate that Delta ligand and Notch receptor expression oscillate in the vertebrate PSM.

Parkinson disease is caused by loss of dopaminergic innervation to the striatum, which can be experimentally induced by 6-OH-dopamine. We describe how to perform a stereotaxic lesion and to monitor apomorphine-induced rotational behavior in mice. This model is useful and reliable for testing new therapies for Parkinson disease.
FAQs
Symptoms depend on which temporal-bone pathways or neighboring structures are affected. Involvement of the middle or inner ear can account for hearing or balance changes, while extension toward the facial nerve canal can produce facial-nerve findings. Contact with adjacent brain structures broadens the neurological significance, making symptom patterns useful for anatomical localization.
Bone destruction and bone remodeling provide different radiologic patterns of structural change. Destruction suggests loss of existing bone, whereas remodeling indicates alteration of bone architecture over time. Interpreting these patterns alongside the involved compartment can help characterize how a lesion is behaving and clarify why cross-sectional imaging is important for clinical assessment.
The middle ear, inner ear, facial nerve canal, vascular channels, and nearby brain structures form the key anatomical reference points. A lesion’s relationship to these structures helps connect imaging findings with hearing, vestibular, facial-nerve, or neurological symptoms. This structure-based interpretation is especially important because the temporal bone occupies a complex part of the cranial base.
Temporal bone lesions can reflect infection, inflammation, trauma, developmental change, or neoplastic growth. These categories describe different possible origins, so clinicians must interpret the observed tissue or bone abnormality in context rather than infer a cause from location alone. Linking the cause with the affected structures helps explain the clinical presentation and supports more focused planning.
Evaluation combines an otologic examination with cross-sectional imaging. The examination assesses findings relevant to the ear and related functions, while imaging shows the lesion’s location and its effect on surrounding bone and structures. Using both approaches provides complementary information, helping clinicians correlate physical findings with anatomical changes rather than relying on either source alone.
Cross-sectional imaging helps map whether a lesion involves the middle or inner ear, facial nerve canal, vascular channels, or adjacent brain structures. That anatomical map can explain presenting symptoms and identify the extent of structural involvement. In turn, these findings guide treatment planning by showing which regions may require particular clinical attention.
Within neuroscience, these lesions illustrate how skull-base anatomy can influence sensory and neural function. Hearing and balance organs, the facial nerve pathway, vascular channels, and neighboring brain structures lie in close proximity, so a local abnormality may have effects across several systems. Studying those relationships supports symptom localization and clinically informed interpretation of imaging.
