In Babinski test, downward toe indicates what?

Explanation:
The test checks the plantar reflex to gauge corticospinal tract function. A healthy adult normally shows plantar flexion of the toes when the sole is stroked, so a downward toe is the normal, expected response. An upward big toe with toe spreading would be a positive Babinski sign, suggesting an upper motor neuron problem. Note that in infants, an upward response can be normal due to immature motor pathways.
