CA1 (Field CA1) synapses onto IB (Interbrain)

Four days after PRV 152 was placed in the posterior lobe of the pituitary, EGFP-positive somata were seen in hippocampal field CA1; because the tracer crosses synapses, the authors describe these regions as directly or indirectly linked to the posterior lobe, so a monosynaptic link is not established.

Made by an AI model reading the paper (claude-opus-5, extract@0.3.0); a second AI model (claude-opus-5) agrees.
