Rat's Move Their Eyes In Opposite Directions When Running For Unique View
2013-05-28 14:17:27

Lee Rannals for redOrbit.com — Your Universe Online Max Planck Institute (MPG) scientists have found that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running. This gives the rats a unique perspective on the world around them. The team discovered that each rat eye moves in a different direction, depending on the change in the animals' head position. They analyzed both eyes and found that one of the eye movements exclude the...

Internal GPS Guides Rats To Rewards
2013-04-18 08:48:04

April Flowers for redOrbit.com - Your Universe Online Scientists at Johns Hopkins University studying rats' ability to navigate familiar territory found that remembered spatial information is used by one particular brain structure to imagine routes that the rats then follow. Understanding why damage to that structure disrupts specific types of memory and learning could have implications for people with Alzheimer's disease and age-related cognitive decline. The model developed for this...

Rodents recognize objects using sophisticated perceptive strategies Sight is such a spontaneous activity that we are unaware of the complexity of the brain mechanisms it implies. For instance, we easily recognize objects, which appear to look always the same, without realizing that we observe them from ever-changing points of view and that their image — the luminance profile cast onto the retina —varies significantly each time we look at them. To maintain such "invariance"...

2012-07-04 11:09:29

The Jamaican rice rat (Oryzomys antillarum) is an extinct species of rodent that was once found in Jamaica. This rat is thought to have been a divergence of O. couesi, which can be found in mainland Central America. It is thought that this rat went extinct in the late 19th century due to habitat destruction and by predation and competition from introduced species like the mongoose and the brown rat. Elliott Coues noted two specimens of Oryzomys in his 1877 monograph about North American...
