eg learned social or cultural passing down of info from on generation to the next
How does complexity of behaviour differ?
Answer 5
At what levels can neural function be defined?
-The brain-Neural Cells (neurons and glia)
-neurotransmitters

--> we can now record neural function at all of these different levels
What brain structure is responsible for most conscious behaviours?
Forbrain

-prominant in mammals and birds
What brain structure is the source of behaviour in simpler animals?
Brainstem

-responsible for most of our unconscious behaviours
What are the four lobes of the brain and their general function
