Are stria terminalis considered as projection fibers?

Answer 1

Projection fibers are usually considered as those fibers that connect the cerebral cortex to subcortical structures and vice versa. The stria terminalis connects the amygdala to the hypothalamus - i.e., two subcortical structures. So, on this basis they are not projection fibers. But because they connect subcortical structures they are referred to as 'association fibers'.

Answer 2

Yes, the stria terminalis is considered as a group of projection fibers in the brain. It connects the amygdala and hippocampus with several other brain regions, including the hypothalamus and septal nuclei. These fibers play a role in regulating emotional and stress responses in the brain.
