To test whether the hippocampus could actually form spatial maps using only visual landmarks, Mehta's team devised a noninvasive virtual reality environment and studied how the hippocampal neurons in the brains of rats reacted in the virtual world without the ability to use smells and sounds as cues.

Is visual input essential to how the topographical map of the visual cortex develops in the human brain?

«Some of the brain's connectivity maps is hardwired, possibly dependent on genetically - driven processes that do not need any external sensory information for their activation, while other process might indeed need visual input to specialize,» Amedi said.

«Though the «blind brain» wiring may change greatly in the blind in its frontal language related parts, it still retains the most fundamental topographical and functional connectivity organizational principles of the visual cortex, known as «retinotopic mapping» — the processing of two - dimensional visual images through the eye,» said co-lead researcher Amir Amedi, associate professor of medical neurobiology at the Hebrew University's Edmond and Lily Safra Center for Brain Sciences and IMRIC, the Institute for Medical Research Israel - Cabrain» wiring may change greatly in the blind in its frontal language related parts, it still retains the most fundamental topographical and functional connectivity organizational principles of the visual cortex, known as «retinotopic mapping» — the processing of two - dimensional visual images through the eye,» said co-lead researcher Amir Amedi, associate professor of medical neurobiology at the Hebrew University's Edmond and Lily Safra Center for Brain Sciences and IMRIC, the Institute for Medical Research Israel - CaBrain Sciences and IMRIC, the Institute for Medical Research Israel - Canada.
