description Paxinos & Watson Rat Brain Atlas Overview
The Paxinos & Watson Rat Brain Atlas provides a detailed three-dimensional map of the rat brain. Published originally in 1982, it’s a cornerstone resource for neuroscientists conducting research into brain structure and function. This atlas features precise stereotaxic coordinates allowing researchers to accurately target specific brain regions during experiments. It is particularly valuable for those involved in preclinical neuroscience studies examining neural circuits, development, or disease models within the rat.
help Paxinos & Watson Rat Brain Atlas FAQ
What is the Paxinos & Watson Rat Brain Atlas used for?
The Paxinos & Watson Rat Brain Atlas is primarily used by neuroscientists to precisely map and target specific regions of the rat brain during stereotaxic surgery. It provides highly detailed 3D coordinates for anatomical structures. Researchers rely on it for tasks ranging from injecting viral vectors to placing recording electrodes.
Who wrote "The Rat Brain in Stereotaxic Coordinates"?
The atlas was co-authored by George Paxinos and Charles Watson, first published in 1982. Their combined expertise in neuroscience and anatomy resulted in what is considered a cornerstone text in the field. It has since gone through multiple updated editions reflecting new scientific discoveries.
How does the atlas help with stereotaxic surgery?
The atlas contains accurate scaled drawings of brain sections with exact measurements from Bregma, a crucial reference point on the skull. Surgeons use these coordinates to calculate the precise depth and anterior-posterior positioning needed for their instruments. This ensures that lesions or implants are placed exactly in the intended brain region.
Are there different versions of the Paxinos and Watson atlas?
Yes, there are multiple editions of the atlas, including versions tailored to specific rat strains, mice, and even developing animals. The seventh edition of "The Rat Brain in Stereotaxic Coordinates" is among the most widely cited scientific texts in the world. They also offer atlases in different planes, such as coronal and sagittal.
