Which of the following best describes why afterimages occur?
A)
Due to the opponent-process functioning of colour receptors, whenever a receptor is activated it will enter the opponent colour state following a briefinterval.
B)
Due to the opponent-process functioning of colour receptors, a receptor that has been activated for an extended period of time will then go into the opposite state.
C)
Due to the centre-surround activation of colour receptors, both colours are activated when a cell is exicted, with one colour appearing as the initial image and one as the afterimage.
D)
Due to the centre-surround activation of colour receptors, one colour will be activated when the cell's firing is above baseline, signaling nearby receptors to activate the complementary colour state.
