AI Article Synopsis
- The homing pigeon serves as a key model species for studying how birds navigate using their brains.
- The olfactory system helps create an "olfactory map," allowing pigeons to determine their location relative to home when in unfamiliar areas.
- GPS-tracking technology has enhanced understanding of how pigeons use environmental scents and visual landmarks for navigation, revealing new insights into the hippocampal area's role in spatial perception.
Article Abstract
The homing pigeon is the foundational model species used to investigate the neural control of avian navigation. The olfactory system is critically involved in implementing the so-called olfactory map, used to locate position relative to home from unfamiliar locations. The hippocampal formation supports a complementary navigational system based on familiar visual landmarks. Insight into the neural control of pigeon navigation has been revolutionised by GPS-tracking technology, which has been crucial for both detailing the critical role of environmental odours for navigation over unfamiliar areas as well as offering unprecedented insight into the role of the hippocampal formation in visual landscape/landmark-based navigation, including a possible, unexpected role in visual-spatial perception.
