Postnatal development of the primate hippocampal formation

Area of Science:

• Neuroscience
• Developmental Biology
• Primate Neuroanatomy

Background:

• The hippocampal formation is crucial for memory processing.
• Its protracted functional maturation in primates is key.
• Developmental abnormalities are linked to neurodevelopmental disorders.

Purpose of the Study:

• To systematically review primate hippocampal formation's structural development.
• To present new data on postnatal neuroanatomical development.
• To understand neurobiological processes underlying maturation.

Main Methods:

• Review of current knowledge on structural development.
• Presentation of new postnatal neuroanatomical data.
• Summary of neurobiological processes (neurogenesis, connectivity, neurochemistry).

Main Results:

• Significant gaps exist in understanding primate hippocampal maturation.
• Distinct developmental windows for hippocampal regions are not yet identified.
• Specific ages for circuit maturation remain undetermined.

Conclusions:

• More systematic studies on monkey hippocampal development are needed.
• Understanding primate development is crucial for insights into human neurodevelopmental disorders.
• Further research will clarify information processing and affected maturational processes.
