Stratum Radiatum Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Stratum Radiatum is a lamina within the hippocampal CA1 region that contains the apical dendrites of CA1 pyramidal neurons, their synaptic contacts, and various interneurons. It is the primary site of Schaffer collateral input from CA3 pyramidal neurons, making it crucial for hippocampal information processing and memory consolidation[1][2].
The stratum radiatum is located in the hippocampal formation:
| Cell Type | Features | Function |
|---|---|---|
| CA1 apical dendrites | Spiny, thorny excrescences | Receive Schaffer collateral input |
| Basket cells | Axo-somatic synapses | Perisomatic inhibition |
| Schaffer collateral-associated interneurons | Axo-axonic | Input regulation |
| OLM cells | stratum oriens-lacunosum moleculare | Feedback inhibition |
| VIP interneurons | Disinhibition | Network modulation |
