Left Stria Terminalis (Stria terminalis sinister)
Educational content only — not medical advice.
Anatomy
The left stria terminalis is a slender C-shaped white matter bundle that serves as the major efferent pathway of the amygdala, running in the groove between the caudate nucleus and thalamus to project to the bed nucleus of the stria terminalis (BNST) and hypothalamus, regulating anxiety, neuroendocrine stress responses, and social behavior.
Clinical notes
Crucial for maintaining sustained fear and chronic stress states (unlike acute fear mediated by the central amygdalar nucleus).
