Maybe these "humanizing" features make most people tear up and spontaneously place their hands over their hearts out of sheer patriotism, but they make me unpleasantly cynical and bitter.
Moreover, when forced to suckle instead of being allowed to suckle spontaneously, newborns place their tongues inappropriately around the nipple [33].
In previous work, we have shown that a dilute suspension of colloidal particles will spontaneously flow when placed in a container.
This catheterization is not feasible in awake mice, and anesthesia in spontaneously breathing mice placed in a supine position for instrumentation probably results in hypoventilation, thereby provoking major bias to the sensitive readout performed here.
Without any training, 78% spontaneously picked up sticks placed in their enclosures and used them to extract food from crevices in pieces of wood, much as New Caledonian crows use twigs to pry grubs and insects from rotted logs.
Fig. 2 Analysis of cardiopulmonary functions of conscious, spontaneously breathing, unrestrained rats placed in whole-body barometric flow-plethysmographs (food and water accessible) from the end of exposure to phosgene until the next morning during a data collection-period of 20 h.
Measurements were made in conscious, spontaneously breathing restrained rats placed in nose-only volume-displacement plethysmographs (pressure = const).. Animals were exposed in three subsequent steps to air (15-min, pre-exposure baseline data), phosgene (30-min, hatched bar), and air again (30-min, recovery).
Briefly, unrestrained, spontaneously breathing mice were placed in plethysmographs and challenged with aerosols of PBS and increasing concentrations of MCh.
The spontaneously breathing monkeys were placed on a heating pad to maintain body temperature in a lateral recumbency.
