Trisynaptic circuit

From WikiMD's Food, Medicine & Wellness Encyclopedia

Trisynaptic circuit is a part of the hippocampus in the brain that is involved in the process of memory formation. The term "trisynaptic" refers to the three synapses that are involved in this circuit.

Etymology[edit | edit source]

The term "trisynaptic" comes from the Greek words "tri," meaning three, and "synapsis," meaning conjunction. This refers to the three synapses that are involved in the circuit.

Structure[edit | edit source]

The trisynaptic circuit begins in the dentate gyrus, where information from the entorhinal cortex is received. This information is then sent to the CA3 region of the hippocampus via the mossy fiber pathway. From the CA3 region, the information is sent to the CA1 region via the Schaffer collateral pathway. Finally, the information is sent back to the entorhinal cortex, completing the circuit.

Function[edit | edit source]

The trisynaptic circuit is involved in the process of memory formation. It is thought to play a role in the encoding of new memories and the retrieval of old ones. The circuit is also involved in spatial navigation.
