If panoramic vision induces calm through the parasympathetic nervous system, does tunnel vision induce adrenaline through the sympathetic nervous system?

Yes—with a useful qualification: tunnel-like visual focus is associated with greater alertness and sympathetic arousal, including epinephrine (adrenaline) and norepinephrine-related activity. The transcripts describe the visual shift and autonomic response, rather than claiming that tunnel vision alone always causes an adrenaline surge.

• Narrowing the visual field: Focusing on a specific target contracts the visual window and engages alertness circuits, including the locus coeruleus. In discussion of stress, tunnel-like vision is also linked with adrenaline release and increased concentration. 1 2
• Broadening the gaze: Widening into panoramic vision tends to promote relaxation and parasympathetic activity, easing the system away from sympathetic activation. It can also support efficient performance, while narrow focus can help generate effort when needed. 3 4
