Dopamine & Serotonin in Animal Social Behaviour Flashcards
What are the 8 behavioural processes modulated by SEROTONIN?
Mood
Perception
reward
anger
aggression
appetite
memory
attention
What does serotonin bind to ?
serotonergic receptors
What socially affiliative behaviours is serotonin associated with in primate models?
Grooming
approaching others
What does serotonin control in decision making?
regulating emotions during social decision making
what is low levels of serotonin associated with in humans?
Impulsive aggression
What does dopamine bind to
dopaminergic receptors
What neuropsychological processes is dopamine involved in (3)
locomotion
learning
working memory
cognition
emotion
motivation
pleasure control
How does dopamine affect some adaptive behaviours?
It reinforces beneficial behaviours (i.e: social monogamy in Prairie voles)
What is dopamine?
an evolutionarily ancient biogenic amine that is found in most eukaryotes and involved in evaluation of stimulus salience
- controls reward system of brain
- critical role in social behaviour
In bees, how does DA affect behaviour?
queen bee releases pheromones that lowers DA levels in workers (modulates their behaviour towards colony chores)
What does DA do in prairie voles?
reinforces pair bond formation and monogamy
Name 2 areas of the brain where dopaminergic receptors are located
the SBN
Substantia nigra
Name 3 social behaviours that dopamine intrinsicly reinforces
- pair bonding
- parent-offspring attachment
- affiliative relationships
- play
- social recognition & memory
- vocal communication
- prosocial networks
- social hierarchy

How does dopaminergic reward signally lead to adaptive behaviours?
- Reinforcement of adaptive behaviours ultimately leads to repetition of behaviours
- Behaviours are inherited genetically or via learning
- Dopamine reinforcement ensures the adaptive behaviours persist in future generations.
