Entorhinal Cortex Layer Iii Pyramidal 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.
Entorhinal Cortex Layer III Pyramidal Neurons constitute the primary hippocampal relay from the entorhinal cortex to the CA1 region. These neurons are critically involved in spatial navigation, memory encoding, and are among the first neurons to show tau pathology in Alzheimer's disease.
| Property | Value |
|---|---|
| Category | Cell Types |
| Brain Region | Medial Temporal Lobe, Entorhinal Cortex |
| Neurotransmitter | Glutamate (excitatory) |
| Cell Type | Pyramidal neuron |
| Layer | Layer III (L3) |
| Associated Diseases | Alzheimer's Disease, Temporal Lobe Epilepsy, FTD |
Entorhinal Cortex Layer II (Grid Cells) → Dentate Gyrus → CA3 (Pattern Separation)
Entorhinal Cortex Layer III (Border Cells) → CA1 (Pattern Completion)
Spatial Navigation:
Memory Encoding:
Temporal Context:
NFT formation → Microtubule disruption → Impaired axonal transport
→ Synaptic dysfunction → Neuronal loss → Hippocampal disconnection
