noticeable delay in heartrate variation at the time of change of raycast direction. In mid-day testing, learning and recall decisionmaking might appear to be significantly greater than in dusk-based sessions for a wide variety of dementia related diseases. This is because the pathway between the photosensitive retinoganglion cells to the thalamocortical nuclei may be compromised by the disease, such that the hippocampal cells via the retinohypothalamic tract do not receive sufficient daylight phase management information. The loss of daylight wavelength variation from pre-dawn to post-dusk impairs conscious-state transition and increases patient confusion and risk of sleep disruption and hallucination.
