How does lateral inhibition occur?
Lateral inhibition is the process by which stimulated neurons inhibit the activity of nearby neurons. In lateral inhibition, nerve signals to neighboring neurons (positioned laterally to the excited neurons) are diminished.
Which of the following occurs because of lateral inhibition?
Lateral inhibition increases the contrast and sharpness in visual response. This phenomenon already occurs in the mammalian retina. In the dark, a small light stimulus will enhance the different photoreceptors (rod cells). This mechanism also creates the Mach band visual effect.
What occurs during lateral inhibition quizlet?
a process in which lateral connections allow one photoreceptor to inhibit the responsiveness of its neighbor, thus enhancing the sensation of visual contrast.
What are lateral interactions?
The influence of signals generated by retinal neurons on the activity of other neurons laterally distant in the retina. Lateral interactions occur at all levels in the retina, from the Photoreceptors, the input neurons of the retina, through to ganglion cells ( Retinal ganglion cells), the output neurons of the retina.
What is the function of lateral inhibition in the retina quizlet?
What is the function of lateral inhibition in the retina?
Retinal lateral inhibition (RLI) is also known as contrast encoder. RLI creates a stimulation contrast allowing increased sensory perception and enhances the contrast between the center and the periphery in a stimulated region.
What is lateral feedback?
1. feedback from “higher” areas to lower areas, e.g., “top-down” connections from V2 back to V1, as well as. 2. lateral (horizontal) interactions, by which we mean here connections between features in the same stage, e.g., connections between simple cells.
Which type of cells mediate lateral inhibition in the retina?
Lateral inhibition is produced in the retina by interneurons (horizontal and amacrine cells) that pool signals over a neighborhood of presynaptic feedforward cells (photoreceptors and bipolar cells) and send inhibitory signals back to them [14–17] (Fig 2).
What is lateral connections neural network?
computational models such as convolutional neural networks (CNNs), lateral connections are implemented using inter-and intra-feature-map interactions of neurons within a single layer with neighboring receptive fields.
What is lateral inhibition quizlet?
lateral inhibition produces a perception of increased brightness on the bright side of boundary, a perception of increased darkness on the dark side of a boundary- serves to sharpen the edges.
