Result
present
Method
transsynaptic tracer
Sign
unknown
Strength
strong
Evidence
Monosynaptic rabies tracing from Kremen1-Cre striatal starter cells showed that the cortex supplied most of the brain-wide presynaptic input neurons, about 85%, with a strong ipsilateral bias.
Measurements

Named in the paper
“cerebral cortex” and “Kremen1+ SPNs in dorsal striatum”
Made by
an AI model reading the paper (claude-opus-5-5, extract@0.3.0), 2026-10-10
Checked by

a second AI model (claude-opus-5-5) agrees, 2026-10-10

“Fig. 2C gives cortex about 85% of inputs, and the strong ipsilateral bias is shown in the same figure.”
