How are pig and human brains different?

How are pig and human brains different?

First, the human brain is only 7.5 times the size of an average pig brain. Typically a brain that has more convolutions (i.e. gyrencephalic) is associated with higher connectivity and complexity. The pig brain is similar to humans in that it has a gyrencephalic brain again making it an easily translatable model.
