Two-way traffic in the brain is crucial for seeing objects

5 July 2017

Visual information from our eyes first enters the brain’s visual cortex at lower areas where elementary image characteristics are encoded. It later reached higher processing levels where objects are identified and recognized. The way in which visual information travels through the brain depends on the direction in which it travels.

Information from lower areas is transmitted truthfully to higher level areas, whereas information that is sent back from higher areas to the lower areas strongly depends on the interpretation of the visual world.

This is demonstrated by recent research of the Vision & Cognition group (Netherlands Institute for Neuroscience), published in the prestigious international journal Neuron on 5 July 2017. Using electrical brain stimulation, the researchers show that signals that are sent back from higher brain area are crucial in recognizing where an object ends and the background begins.

Netherlands Institute for Neuroscience

The Netherlands Institute for Neuroscience is an Academy research institute. It conducts basic and strategic research in the neurosciences. It examines how the human brain makes awareness, perception, movement, learning, social interaction and other cognitive functions possible. It also studies how brain disorders can disrupt these functions.
