Proof For Theory Of Visual Perception
Researchers at the Technical University of Munich have confirmed the validity of the 1981 Nobel Prize-winning model of visual perception by David Hubel and Torsten Wiesel. The study used high-resolution imaging to analyze signal transmission between the thalamus and the visual cortex, resolving a long-standing controversy in the field of neuroscience.
A scientific dispute about visual perception in mammals has been settled by researchers at the Technical University of Munich. They used a high-resolution imaging approach to measure synaptic activity in the intact brain. The study found that signals arriving from the thalamus were robust but non-specific, while orientation selectivity emerged through processing within cortical circuits. This confirms the model proposed by Hubel and Wiesel, which suggested that visual perception is the result of orderly computations in the brain. The research team developed a new method for analyzing synaptic function, which can be applied to other areas of neuroscience. The findings were published in the journal Science.
