Final answer:
The content provided does not precisely address 'humoral vision' but rather discusses neurological and visual occurrences over extended periods, ranging from years to nearly seven decades.
Step-by-step explanation:
The query appears to be addressing neurological and visual phenomena, specifically the duration of certain symptoms like binocular vision, peripheral vision loss, and the onset of paralysis and subsequent biological changes. The reference to humoral vision mentioned in the question does not directly relate to the content provided. Instead, the content discusses clinical presentations such as the development of binocular vision in an individual named Bruce, who took nearly 70 years to have these cells activated, and visual conditions like bilateral hemianopia, which occurs when a growth impinges on the optic chiasm, causing loss of lateral peripheral vision. Also mentioned is the case of Leborgne, who experienced a progression of symptoms over several years, including paralysis and deterioration of vision and mental faculties prior to his death. These scenarios involve complex interactions between the nervous system and the visual system but do not singularly address 'humoral vision,' which may refer to an outdated concept in medical history regarding bodily fluids influencing health and disposition.
