Patient D. B. was able to locate spots of light presented in his blind field even though he could not see them because his:

A) geniculostriate pathway was intact.
B) retinohypothalamic pathway was still intact.
C) tectopulvinar pathway was still intact.
D) dorsal stream was damaged.

Retinohypothalamic Pathway

The retinohypothalamic pathway is a part of the eye-brain connection that helps regulate the circadian rhythm by conveying light information from the retina to the hypothalamus.

Geniculostriate Pathway

The major visual pathway in the brain, which runs from the retina to the primary visual cortex via the lateral geniculate nucleus of the thalamus.

Tectopulvinar Pathway

A pathway in the visual system that connects the superior colliculus with the pulvinar nucleus of the thalamus, involved in the processing of visual information related to motion and spatial orientation.
