Question 1

Which brain region is primarily responsible for processing fear responses and is often hyperactivated in traumatized children?

Accepted Answer

Amygdala

Answer

The amygdala detects threat and triggers the fear response, and chronic trauma can leave it in a state of heightened activation.

Question 2

The term 'window of tolerance' in trauma neuroscience refers to:

Accepted Answer

The optimal zone of arousal in which a child can process experiences effectively

Answer

The window of tolerance describes the arousal zone where the nervous system can function adaptively without becoming hyper- or hypo-aroused.

Question 3

Which stress hormone, when chronically elevated in traumatized children, can suppress immune function and impair hippocampal memory consolidation?

Accepted Answer

Cortisol

Answer

Chronically elevated cortisol from toxic stress damages hippocampal neurons and dysregulates immune responses in children.

Question 4

Polyvagal theory, developed by Stephen Porges, emphasizes the role of the __________ in social engagement and trauma response.

Accepted Answer

Parasympathetic vagal pathways

Answer

Polyvagal theory highlights how the ventral vagal complex supports social engagement, while dorsal vagal shutdown underlies freeze/dissociation responses.

Question 5

Neuroplasticity in the context of childhood trauma treatment most importantly means:

Accepted Answer

The brain retains the capacity to form new neural pathways through therapeutic experiences

Answer

Neuroplasticity means the brain can reorganize and build new connections throughout development, giving trauma-informed interventions biological efficacy.
