How brain injury can lead to post-traumatic stress disorder

Traumatic brain injury caused five times as many neurons in the amygdala to be active during white noise exposure in rats. Altered sensory processing within subcortical sensory-emotional networks following TBI impacts the facilitation of traumatic memory and may contribute to the development of PTSD.

Why the Memory of Fear Is Seared Into Our Brains

Norepinephrine facilitates fear processing by stimulating a population of inhibitory neurons in the amygdala, generating repetitive bursting patterns of electrical activity. This activity changes the frequency of oscillations in the amygdala from resting state to aroused state, promoting the formation of fear memories.

Proof it’s possible to enhance or suppress memories

Using optogenetics to stimulate different areas of the hippocampus has the ability to enhance or suppress memories in mice. The findings could have implications for suppressing memories associated with traumatic events in PTSD, and also in enhancing cognitive ability or improving memory for those with neurodegenerative diseases, in the future.

Human Screams Communicate At Least Six Emotions

Study identifies six psycho-acoustically distinct types of screams, relaying emotions such as pain, anger, fear, joy, sadness, and pleasure. Non-alarming screams, such as expressions of joy and pleasure, are perceived and processed by the brain more effectively than screams of alarm.

The Brain Uses Bodily Signals to Regulate Fear

Study reveals how the brain relies on feedback from the body to regulate fear response. When a mouse's body freezes in response to fear, its heart rate slows, and this leads to attenuated insular cortex activity.
