What did Hubel and Wiesel demonstrate about how visual processing works?
What did Hubel and Wiesel demonstrate about how visual processing works?
Hubel and Wiesel’s findings were not just an advance but a quantum leap in our understanding of visual cortex. They showed how the pointillism of the retina is transformed into the orientation sensitivity in cortex.
What did Hubel and Wiesel measure?
They called these “ocular dominance columns”. They also measured how distinct neurons respond to distinct visual features, such as the orientation of a line projected on a screen, or specific patterns of lines. These experiments were instrumental to our understanding of visual processing.
What did Hubel and Wiesel discover?
Hubel and Wiesel concluded that an abnormality occurred somewhere within the visual pathway from the eye to the brain that caused the cortical neurons to redistribute and function only with the normal eye. Hubel and Wiesel investigated where in the vision pathway the abnormality of vision cells came from.
What did the work of David Hubel and Torsten Wiesel contribute to our understanding of feature detectors?
David Hubel and Torsten Wiesel demonstrated that specialized neurons in the occipital lobe’s visual cortex respond to specific features of an image such as angles, lines, curves, & movement.
When Hubel and Wiesel Monocularly deprived a cat during its visual system development the result was?
David Hubel and Torsten Wiesel’s experiments showed that if a kitten is deprived of normal visual experience during a critical period at the start of its life, the circuitry of the neurons in its visual cortex is irreversibly altered. In each of a number of newborn kittens, one eyelid was sutured shut.
What did Hubel and Wiesel discover quizlet?
Hubel and Wiesel discovered feature detector cells in the visual cortex that respond selectively to: lines at different orientations.
What is Torsten Wiesel known for?
Torsten Nils Wiesel (born 3 June 1924) is a Swedish neurophysiologist. With David H. Hubel, he received the 1981 Nobel Prize in Physiology or Medicine, for their discoveries concerning information processing in the visual system; the prize was shared with Roger W.
What is David Hubel known for?
David Hubel, who has died aged 87, was one of the greats of neuroscience. He discovered how individual brain cells convey the information that enables us to see the world, how these cells are organised in an exquisite crystalline structure and how they are moulded by experience in early life.
What did Torsten Wiesel contribution to psychology?
Hubel and Wiesel’s experiments showed that the ocular dominance develops irreversibly early in childhood development. These studies opened the door for the understanding and treatment of childhood cataracts and strabismus. They were also important in the study of cortical plasticity (Goldstein, 2001).
Who discovered feature detectors?
Feature detection was discovered by David Hubel and Torsten Wiesel of Harvard University, an accomplishment which won them the 1981 Nobel Prize.
How did Hubel contribute to psychology?
What are the 3 feature detectors?
The three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells.
