What is the stratum Lacunosum Moleculare?
The so-called stratum lacunosum-moleculare (SLM) is a hippocampal layer close to the hippocampal fissure and the dentate gyrus. This layer of the hippocampus is important because it serves as a relay between the entorhinal cortex (EC) and the CA1 hippocampus.
What is the stratum oriens?
Stratum oriens (str. oriens) is the next layer superficial to the alveus. The cell bodies of inhibitory basket cells and horizontal trilaminar cells, named for their axons innervating three layers—the oriens, Pyramidal, and radiatum are located in this stratum.
What is the CA1 region of the hippocampus?
CA1. CA1 is the first region in the hippocampal circuit, from which a major output pathway goes to layer V of the entorhinal cortex. Another significant output is to the subiculum.
Is the subiculum part of the hippocampus?
The subiculum (plural: subicula) is located in the mesial temporal lobe and is a subdivision of the hippocampal formation, along with Ammon’s horn, the entorhinal cortex and the hippocampus proper. It is the predominant output source of the hippocampal formation.
What does Cornu Ammonis mean?
Filters. (paleontology, obsolete) A fossil shell, curved like a ram’s horn; an ammonite. noun. (anatomy, obsolete) The hippocampus of the brain.
What does CA1 stand for?
CA1
| Acronym | Definition |
|---|---|
| CA1 | Carbonic Anhydrase 1 (genetics) |
| CA1 | Cornu Ammonis-1 (psychology) |
| CA1 | Cortical Area 1 (pyramid cells) |

What is a CA1 neuron?
Within the hippocampal memory system, CA1 neurons are critically involved the formation, consolidation, and retrieval of hippocampal-dependant memories. This finding suggests that hippocampal CA1 neurons might have an important long-term role in the retrieval of remote memories.
