The nucleus of the solitary tract (NTS) contains a unique subpopulation of neurons that express the enzyme 11-beta-hydroxysteroid dehydrogenase type 2 (HSD2). These neurons are mineralocorticoid-sensitive and are activated in association with salt appetite during sodium deficiency. In the absence of sodium deficiency, the HSD2 neurons and sodium appetite are both stimulated by chronic mineralocorticoid administration. After 7 days of treatment with deoxycorticosterone (2 mg/day), an increased number of HSD2 neurons became immunoreactive for the neuronal activity marker c-Fos. When given access to concentrated saline (3% NaCl), deoxycorticosterone-treated rats drank eight times more than vehicle-treated rats. Saline ingestion increased neuronal activation within the medial subdivision of the NTS, but the number of c-Fos-immunoreactive HSD2 neurons was reduced. This finding suggests that the HSD2 neurons are inhibited by signals directly related to saline ingestion, and not simply by the alleviation of sodium deficiency, which does not occur during mineralocorticoid administration.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 January 2013.
All research outputs
#9,516,022
of 27,782,313 outputs
Outputs from Brain Research
#2,975
of 10,039 outputs
Outputs of similar age
#36,057
of 99,958 outputs
Outputs of similar age from Brain Research
#33
of 87 outputs
Altmetric has tracked 27,782,313 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 10,039 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 26th percentile – i.e., 26% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 99,958 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 87 others from the same source and published within six weeks on either side of this one. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
