Definition: Nocusculus refers to the brain's ability to form new memories after a traumatic event or experience, often through direct exposure to the sensory inputs that triggered it. This state occurs in some people with trauma-related disorders like PTSD, which involves persistent fears and avoidance reactions following intense life events. The exact definition of "nocusus" is subjective, but generally, it means the brain's ability to store new information and memories from previous experiences, which can be crucial for recovery after trauma.
