That they work both ways.
Conserved characteristics?
Some features multiple species share because they arose in a shared ancestor.
Ontogeny?
The process by which an individual change in the course of its lifetime

The ability of the brain to be changed by the environment and by experience.
Reductionism?

Broca’s area?
Speech production.
Where can you find the neurotransmitter?
At the end of the axons.

The field that related behavior to bodily processes.
Who were the first people to study the relationship between brain and behavior?
Philosophers.
In which way do neuroplasticity play a role when becoming a mother?
When women become a mother, their baby’s cry causes the mother’s brain to secrete a hormone – this shows that experience alters the structure and/or function of the brain.
