What brain circuits are involved in the fear response?
Two separate pathways!
Amygdala sends automatic responses: Sweaty palms, increased heart rate
Circuit going through the cortex: Gives us a false alarm, a slower pathway that inhibits the amygdala
Which area is impaired in PTSD patients?
The circuit through the cortex, that shuts down the automatic fear responses when not needed.
Why can’t PTSD patients control their fear responses?
They dwell on memories, see their traumatic memories extremely vividly, while they can only vaguely recollect recent memories.
What other brain structure is important in the fear inherent in PTSD patients?
The hippocampus, which plays a vital role in memory.
It is visibly smaller in volume, compared to a normal individual.

What are some of the PTSD symptoms Dennis experiences?
- Intrusive, repetitive memories of the traumatic event that he has little control over
- Nightmares of the traumatic event
- Jumpy, easily startled, hypervigilant
What part of Dennis’s PTSD-bound brain seems to be affected?
- The mechanism that shuts down the fear responses; so in Dennis’s case, even a small fear stimulus leads to terror
- Part of the reason for this may be that Dennis’s terrifying experiences may have altered his hippocampus in such a way to make his long-ago memories of the war dominate his thinking and emotions, so much so that his memories of current events in his life is impaired
