Researchers at the Howard Hughes Medical Institute Janelia Research Campus have discovered that rats have the ability to imagine. There findings indicate that just like people, animals can think about places and objects that they cannot see.

To determine this, they used a Brain Machine Interface and saw that rats showed specific neural activity patterns in the hippocampus area of their brain which is related to spatial memory. The researchers have determined that this function is necessary for an animal to remember past events and imagining future scenarios even if the animal is at a different location.  

Sue’ Note: While this research is important because it gives scientific proof that animals can remember the past and think of the future, it is obvious to me because if animals cannot do this, those in the wild would not survive. Our domestic animals would not be able to learn the things we teach them. An example that many of us have observed is the dog who knows what time a person is coming home and waits at the door, long before he could hear, smell or see the person coming. This is evident when the person is late and the dog at waiting at the normal time and illustrates the dog’s ability to anticipate the future. A famous example of this is Hachikō, an Akita who lived in Japan from 1923 to 1935 and went every day to the train station to wait for his master after his master died.
