Researchers found the brains of three species of stranded dolphins had classic biomarkers associated with human Alzheimer's disease. The findings add weight to the "sick leader" theory, where a group of healthy dolphins finds themselves in dangerously shallow waters after following a group leader showing signs of confusion.
Areas of the genome associated with brain development harbor variants that seem to account for behavioral differences between dog breeds. The genomic differences between dog breeds are related to the development of their nervous systems. Researchers say genes associated with different dog lineages may relate to genes involved in the development of human behavior.
Over the years, many people have reported their pets can communicate with them. There are numerous videos online "demonstrating" animal communication. Researchers investigate whether our pets really can understand what we are saying and communicate back with us.
A new neuroimaging study reveals how dogs process words they have been taught to associate with objects. Findings suggest dogs have a rudimentary neural representation of meaning for words they have been taught.
