Neuroanatomy of Perceptual Binding Flashcards
What is “common fate” in perception?
The ability to bind separate stimuli into a single object
What is perceptual binding? What type of connections mediate this ability?
The perception of stimuli be unified because of some common feature. Mediated by corticocortical connections.
What areas of cortex respond better to images of faces than other types of stimuli?
Inferotemporal cortex, Superior Temporal Polysensory areas.
Give a description of the usefulness of cross correlation histograms in analyzing processing streams?
They give the probability that a target neuron will discharge at some time T, given that a presynaptic neuron discharged at time 0.
What is a possible cellular mechanism for perceptual binding?
corticocortical syncronization of firing. “Imagined lines” in the place of gaps are created by innervation of neurons that perceive the existing lines.
