which of the following sensory pathways directly provides input to the
occipital lobe?
optic tract
optic chiasm
spihothalamic tract
posterior column system

Explanation:

The occipital lobe is the visual processing center of the brain. The optic tract carries visual information from the optic chiasm to the thalamus (lateral geniculate nucleus) and then to the occipital lobe. The optic chiasm is just a crossover point of optic nerves. The spinothalamic tract is involved in pain, temperature, and crude touch sensation (not visual - related to the occipital lobe). The posterior column system is for fine touch, vibration, and proprioception (also not visual).

Answer:

Optic Tract
