Reynolds et al. (1999) measured the responses of a single neuron in area V4 of a macaque monkey. The monkey was trained to keep its eyes on the fixation point at all times and to direct its attention in various ways while the experimenters presented either an effective stimulus, an ineffective stimulus, or both. When the monkey attended to the effective stimulus, the neuron's response was:
A) enhanced as the effective stimulus was presented alone.
B) suppressed as the ineffective stimulus was presented alone.
C) a compromise due to the presence of both the effective and ineffective stimuli.
D) inconsistent, as it did not match the neuron's tuning function.
