The midnight interval was not dead time; it was noticed time, which shapes how long nights are experienced.

—Pallas pour’d sweet slumbers on his soul;If every day did not produce fresh instances of the ingratitude of mankind, we might, perhaps, be at a loss, why so liberal and impartial a benefactor as sleep, should meet with so few historians or panegyrists. Writers are so totally absorbed by the business of the day, as never to turn their attention to that power, whose officious hand so seasonably suspends the burden of life; and without whose interposition man would not be able to endure the fatigue of labour, however rewarded, or the struggle with opposition, however successful.
And balmy dreams, the gift of soft repose,
Calm’d all his pains, and banish’d all his woes. POPE.
Si quis invisum Cereri benignæ
Me putat germen, vehementer errat;
Illa me in partem recipit libenter
Fertilis agri.
Meque frumentumque simul per omnes
Consulens mundo Dea spargit oras;
Crescite, O! dixit, duo magna sustentaculu
vitæ,
Carpe, mortalis, mea dona lætus,
Carpe, nec plantas alias require,
Sed satur panis, satur et soporis,
Cætera sperue,
He wildly errs who thinks I yieldSleep, therefore, as the chief of all earthly blessings, is justly appropriated to industry and temperance; the refreshing rest, and the peaceful night, are the portion only of him who lies down weary with honest labour, and free from the fumes of indigested luxury; it is the just doom of laziness and gluttony, to be inactive without ease, and drowsy without tranquillity.
Precedence in the well-cloth’d field,
Tho’ mix’d with wheat I grow:
Indulgent Ceres knew my worth,
And to adorn the teeming earth,
She bade the Poppy blow.
Nor vainly gay the sight to please,
But blest with pow’r mankind to ease,
The goddess saw me rise:
“Thrive with the life-supporting grain,”
She cried, “the solace of the swain,
The cordial of his eyes.
Seize, happy mortal, seize the good;
My hand supplies thy sleep and food,
And makes thee truly blest:
With plenteous meals enjoy the day,
In slumbers pass the night away,
And leave to fate the rest.” C. B.
Medvedev and his colleagues used a type of brain imaging known as near-infrared spectroscopy, which involves placing optical fibers similar to electrodes symmetrically around a person’s scalp. These “optodes” send infrared light through the brain and measure how much light returns.
The intensity of light bouncing back provides an estimate of the blood flow in different regions of the brain. Blood flow, in turn, is an indicator of how active those regions are.
