The control of different behaviors is a complex process that is
influenced by both genetics and environmental factors, according to a story in Science Daily from May 25. A new study confirms what other researchers have shown - that there's a correlation between aggression that the firing of those neurotransmitters in canine brains.
Here's the technical deal - central nervous system and its neurotransmitters and intricate
networks of receptors play a key role in the study of behavioral
genetics. Serotonin and dopamine are neurotransmitters in the brain and
have an important function in the control of behavior. Many of the
medicines used these days by veterinary behaviorists and veterinarians who know for the treatment of psychological disorders do
have an effect on these neurotransmitters.The psycho-pharmaceuticals don't always solve the problem, but they make learning more possible and dogs somewhat less reactive.
The doctoral study (at it sounds it - warning: be ready for technical stuff) has revealed a variation in genes related to
serotonin and dopamine in dogs. Jørn Våge used these variations as markers
in the study and discovered connections between individual variants of
genes and aggressive behavior in dogs. The neurotransmitter systems have many different receptors and
enzymes that regulate the production and breakdown of psychoactive
substances. All stages of these reactions are controlled by genes and
can be potential sources of behavioral changes.
The thesis also covers studies of genetic activity (expression
studies) in different areas of the brain in aggressive and
non-aggressive dogs respectively.
