After "this activity pattern:" is the unique name we
apply to the pattern shown in the center of the page.
Beneath this name, we indicate the number of rats used
to create that average pattern. Beneath the number of
rats we indicate the parts of odorant per million parts
of vapor (ppm) used during the exposure, if this number
is available. The value is calculated using both the
partial pressure of the odorant as represented on the
molecular properties page and the dilution factor in
air. (In the event that the odorant was first dissolved
in a solvent, we are not currently able to calculate the
ppm in the vapor phase as described in "About our
Methods".) Beneath the value for ppm we give an exposure
description including the dilutions in air and solvent,
if any. In early papers, we used the method of Hass and
Newton to estimate vapor pressures and to calculate ppm
vapor phase concentrations. In the event that we
previously published vapor phase concentrations derived
in this way, this previously published ppm concentration
will be indicated within the notes that appear in a blue
color at the bottom of the pattern information.
Beneath the description of the odor dilution, we provide
a study code that identifies a unique experiment
conducted by our laboratory. (We find that patterns
often show greater similarity within an experiment than
across different experiments, which is not surprising
given that the animals are more closely related to each
other, that the animals have had a more similar
environment during rearing, that they share home cage
odors, that the same cylinders of gas are used during
the exposures, and that a common blank pattern has been
subtracted.) Below the study code, we indicate the print
publication(s) that have utilized the activity pattern.
These papers can be accessed from our Publications
Beneath the publication is a set of notes in blue type
that indicates the relationship of the displayed pattern
to other patterns in our database. Also included in
these notes is any other information that helps to
identify the pattern as well as any comments we might
offer regarding the interpretation of the pattern.
If this page is reached through the "Browse Odorants"
feature of our site, there will be a section on the
bottom of the page with the heading "instances of this
odorant:". In the event that we studied the same odorant
more than once, there will be patterns listed here
beyond the one shown on the page. These patterns can be
accessed by clicking on their names.
