Serotonin is a busy neurotransmitter, influencing processes as memory, mood, emotion, appetite, and sexuality. A prime role for this neurotransmitter is social behavior, across a variety of species; humans, rodents, primates.
Aggressive behavior is adaptive for most species. But how is this aggressive behavior mediated in the brain? A recent study indicates that the hippocampus is a crucial neural component in mediating social recognition.
In Planckendael Wild Animal Park (Belgium), researchers have been observing a group of bonobos and have found that the differences between chimpanzees and bonobos are not always as black and white as generally believed.
The treatment of Fragile X syndrome is limited to the symptoms. One of the factors currently holding back drug development is the difficulty of finding a reliable behavioral test for neurobiological studies.
Women and Venus, men and Mars, right? In mice, the establishment of social hierarchies is sex-dependent.
Domestication has a considerable effect on the behavior of animals. The dramatic change in their environment and provision of food alter the need for behaviors such as exploration. But what exactly is the difference?
Zebrafish. This little fish is a vertebrate, and a relatively complex one. Looking at the major neurotransmitters and hormones that are investigated in neuroscience, they are as good of a model as many mammalian species.
Why do wolves howl? From research, movies, and even television series, we learn that wolves cry out to each other to facilitate the reassembling of a pack when members have strayed.
How to mark zebrafish without compromising their behavior? They may have just found the answer to this at the University of Toronto. Cheung et al. tried out a method using subcutaneous injection with dyes.
As humans, we help each other because it is the right thing to do. We help our friends and our family. And of course we help strangers as well. Right?
