What did Hubel and Wiesel research on the brain show?
What did Hubel and Wiesel research on the brain show?
Hubel and Wiesel demonstrated that some neurons were only responsive to information that came from a single eye, a phenomenon they referred to as “ocular dominance”. Intriguingly, neurons that are tuned to a particular eye cluster together in anatomical columns in the visual cortex of the brain.
What is Hubel and Wiesel theory?
Hubel and Wiesel hypothesized that there was a time period during which the visual nerve cells develop and that if the retina did not receive any visual information at that time, the cells of the visual cortex redistribute their response in favor of the working eye.
What were the research contributions of David Hubel and Torsten?
Hubel and Wiesel received the Nobel Prize for two major contributions: firstly, their work on the development of the visual system, which involved a description of ocular dominance columns in the 1960s and 1970s; and secondly, their work establishing a foundation for visual neurophysiology, describing how signals from …
What did David Hubel and Torsten Wiesel discover about perception and the visual feature detectors in the brain?
Unlike many of the cells in the retina, which respond to spots of light or dark, they found that cells in the visual cortex were highly selective for edges (or lines) of a specific orientation. …
What did David Hubel contribution to psychology?
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 is David Hubel known for?

What did Torsten Wiesel discover?
Wiesel received a total of twenty scientific awards throughout his career, including his Nobel Prize in 1981 for his discovery of the critical period in visual system development as well as research on visual information processing by the visual cortex of the brain.
Why is Torsten Wiesel important to psychology?
Who is David Hubel in psychology?
David Hubel (1926-2013) was a Canadian neurophysiologist that was a co-winner (with partner Torton Weisel and co-recipient Roger W. Sperry) of the 1981 Nobel Prize in Physiology or Medicine for their work on the visual cortex. They had studied how the brain processes information in the visual system.

What did Canadian David Hubel and Swede Torsten Wiesel of Johns Hopkins University in Baltimore discover in their experiment with the cat?
Neurophysiologists Torsten Wiesel and David Hubel, whose early research involved cats staring at black dots on a screen, are responsible for major progress in our understanding of the brain, for significant advances in the treatment of childhood cataracts, and for informing current research to enable computers to …
What did Torsten Wiesel study?
Torsten Nils Wiesel studied visual information processing and development in the US during the twentieth century. He performed multiple experiments on cats in which he sewed one of their eyes shut and monitored the response of the cat’s visual system after opening the sutured eye.
