|July 1, 1977
Summary
Motor control develops heterochronously in chick embryos. Ancient striatal structures mature first, followed by neostriatal and hyperstriatal regions, influencing motor activity regulation.
Area of Science:
- Neuroscience
- Developmental Biology
- Embryology
Context:
- Striatal complex maturation is crucial for motor function.
- Studies on chick embryos reveal developmental timelines.
- Electrical stimulation probes functional development.
Purpose:
- To investigate the heterochronous maturation of striatal structures.
- To understand the sequence of functional development in motor regulation.
- To identify the primary regulatory mechanisms in motor analysis.
Summary:
- Chick embryo studies (17-21 days) show heterochronous maturation of the striatal complex.
- Phylogenetically older archi- and paleostriatum regulate motor activity first.
- Neostriatal mechanisms emerge by day 19, hyperstriatal by hatching.
Impact:
- Provides insights into the developmental neurobiology of motor control.
- Establishes a timeline for striatal functional maturation.
- Highlights the role of ancient brain structures in early motor development.
