Question

Explain what happens once visual signals reach the visual cortex.

a) Visual signals are sent to the brainstem.
b) Visual signals are processed and interpreted.
c) Visual signals are transmitted to the thalamus.
d) Visual signals are stored in the hippocampus.

Answer 1

Once visual signals reach the visual cortex, they are processed and interpreted. The thalamus acts as a routing station for sensory impulses, and from there, visual signals are sent to the primary visual cortex. The visual signals are then sent in different directions to the parietal lobe and the temporal lobe for processing.

Step-by-step explanation:

Once visual signals reach the visual cortex, they are processed and interpreted. The thalamus serves as a routing station for all incoming sensory impulses except olfaction. In the thalamus, there are different layers dedicated to processing visual signals. From the thalamus, visual signals travel to the primary visual cortex at the rear of the brain. The visual signals then travel in two directions - one stream projects to the parietal lobe carrying information about the location or movement of visual stimuli, while a second stream projects to the temporal lobe carrying information about both location and object recognition.
