31. Two or more stimuli that are switched on and off in alternation can produce two different motion percepts . 32. We use the term percept to refer to the agent's perceptional inputs at any given instant. 33. The massive parallelism of neural networks allows redundant populations of neurons to mediate the same or similar percepts . 34. Microstimulation is being explored as a method to deliver sensory percepts to circumvent damaged sensory receptors or pathways. 35. Visual or optical illusions can be categorized according to the nature of the difference between objects and percepts . 36. But there is more to the human being's cognitive inventory than percept , concept and mental picture. 37. Whereas the percept during binocular rivalry alternates stochastically, the percept during flash suppression is precisely controlled in time. 38. Whereas the percept during binocular rivalry alternates stochastically, the percept during flash suppression is precisely controlled in time. 39. Thus, infinitely many different combination of wavelengths produce the exact same color percept in a normal healthy human. 40. Therefore, these receptors are crucial to the metabolic pathway of processing and eliciting for the percept of fear.
