Isocortex functionally connects to CH (Cerebrum)

Blue-light stimulation in the left amygdala of ChR2-expressing terminals from the left lateral neocortex evoked local field potential responses on about half of the recording electrodes, with paired-pulse depression that the authors read as monosynaptic; mice lacking ChR2 showed no light responses.

Made by an AI model reading the paper (claude-opus-5-5, extract@0.3.0); a second AI model (claude-opus-5-5) disagrees. “The 54% is the share of electrodes showing light-evoked responses, not a connection probability, and 6.3 ms is a maximum peak mean latency rather than a measured conduction delay.”
