1.what typically happens in the brain when someone perceives a threat?
2.what happens if this process doesn't work correctly?
3.how might this explain violent behavior?

1: the brain will naturally become strained and fear hormones will be released causing u to become more alert.
2: If fear hormones are not released, you would not be alert and have a higher chance of being harmed if danger is near.
3: When you are not alert you tend to rely on violence more but if you r alert you would probably run away.
