¡°By studying socioeconomic status within a neuroscientific framework, we have the potential to expand our understanding of the biological signatures of poverty,¡± said Nina Kraus, professor of neurobiology, physiology and communication sciences at Northwestern University and an author of the second study, in a statement. ¡°And a better understanding of how experiences shape the brain could inform educational efforts aimed at closing the socioeconomic achievement gap.¡±

Question

What does this mean?
I got that Nina Kraus is the prof of neurobiology, physiology and communication sciences at Northwestern University and said ¡°By studying socioeconomic status within a neuroscientific framework, we have the potential to expand our understanding of the biological signatures of poverty,¡±

but I don't quite understand what these sentences below mean.

an author of the second study, in a statement. ¡°And a better understanding of how experiences shape the brain could inform educational efforts aimed at closing the socioeconomic achievement gap.¡±

are the sentences in quotation marks also the one that Nina Kraus said?
