Exam 3: Neural Processing

 When we view a stimulus with a specific property, neurons tuned to that property fire and will eventually become fatigued, an effect called _____ adaptation.

 Human lateral inhibition is most likely accomplished by _____.

 The flow of information to the _____ from the _____ is greater than from the _____.

Describe the difference between simple cortical cells, complex cortical cells, and end-stopped cells. (b) Explain why these cells are called "feature detectors."

 To measure _____, the experimenter decreases the intensity difference between the light bars and the dark bars until an observer can just barely detect the difference between the dark bars and the light bars.

 You can create a version of the _____ by illuminating a light-colored surface with a desk lamp and casting a shadow with a piece of paper.

 When a kitten is exposed to an environment of just horizontal lines, the kitten _____.

 A stimulus that contains alternating black and white bars is called a _____.

 What happens when the straight lines of the Hermann Grid are made curvy Why is this a problem

 Chad is reading when he sees an insect land on the corner of his book. He then makes an eye movement to look at the insect. The structure of the visual system that is most likely responsible for making this eye movement is the _____.

 In Mach bands, the darker area sends _____ lateral inhibition to the lighter area than the lighter area sends to the darker area.

 The different types of cortical cells that respond to specific stimuli are also known as _____.

 The gray intersections in the Hermann Grid _____.

 _________: Limulus :: ________: human retina.

 The inability of lateral inhibition to explain some perceptual effects suggests that some contrast effects are based in _____.

 The inability of lateral inhibition to account for more complex effects shows how _____.

 ______ cells fire to moving lines of a specific length or to moving corners or angles.

 When _____, lateral inhibition can no longer account for the Hermann Grid.

 _____ coding occurs when a particular object is represented by a pattern of firing of only a small group of neurons, with the majority of neurons remaining silent.

 A receptor array in the Limulus is connected by the lateral plexus. Receptor "A" is located 5 receptors to the left of Receptor "B." What stimulation will result in the greatest firing rate recorded from "A"
