The feature detectors identified by hubel and wiesel respond to specific aspects of visual stimulation.
The answer is visual because with that stimulation they tried to find out the effect of unilateral vision on the primary visual cortex of the brain. According to the work done, it was suggested that if the developing brain is not exposed to superimposed images of the two eyes, it will never form the connections you need to process a three-dimensional scene. The purpose of the experiment was to find out how the brain can develop complex visual images.
I think the answer is this is an example of personification. Sorry if this isn't correct.
Cacophony means a harsh, discordant mixture of sound that is annoying or irritating. A combination of sounds that is not in harmony.
The words that form the clue to the meaning of cacophony are:
1) blare, battered, trumpet
2) smash, cymbals
3) anguished, screech, poorly-played saxophone
Trumpet, cymbals, and saxophone are all musical instruments. If these instruments were in very good condition and were played well, then the sounds they would have produced will be harmonious.
