The Social Brain
Humans, like other mammals, are fundamentally social creatures. A baby's brain can't develop properly without the right social stimulation from the baby's loved ones. A classic early experiment in the 1950s showed that baby monkeys deprived of social interaction try to cuddle with inanimate objects. If the infant monkey is isolated from any social contact, as a juvenile, the monkey shows deficits in play and learning, and is more fearful.This section describes how we understand social signals, the parts in the brain that are involved in processing social information, and how these parts differ in people with ASD.
- We are fundamentally social creatures.
- Faces are critical for communicating. Our eyes and mouth reveal our emotions.
- The brain's social pathway attaches meaning to social signals, motivates us to respond to social signals, and guides our social behavior.
- Key hormones (oxytocin and vasopressin) and neurotransmitters (dopamine) help us bond with other humans and motivate us to do so.
- Deficits in all of these brain regions can be seen in ASD patients.
Our brains develop without the influence of people that surround us.
We are fundamentally social creatures. A baby's brain can't develop properly unless he/she is around other people and provided social stimulation from the ones they love.
