The phrase "a sample of neurons" is correct and usable in written English.
It can be used in scientific or medical contexts when referring to a small selection or representation of neurons for study or analysis.
Example: "In our research, we collected a sample of neurons to examine their response to various stimuli."
Alternatives: "a collection of neurons" or "a subset of neurons".
Quantification of neurite outgrowth was performed over a sample of 200 500 neurons per condition using Leica QWIN Image Analysis software (Leica Microsystems, Bannockburn, IL).
There is some evidence for this in macaque V1 as Cottaris & De Valois (1998) have shown, based on a sample of 95 neurons over 12 monkeys that cortical S-cone opponent signals are selectively amplified by a dynamic non-linearity, possibly based on intra-cortical modulation, yielding a delayed and sluggish S-cone signal in the cortex.
While an increased average firing rate of a local sample of neurons to a certain modulation rate would certainly lead to an increased BOLD response, an increased synchronisation within the same sample of neurons would probably have a similar effect.
To examine the possibility that SA currents are expressed in neurons derived from high-threshold mechanonociceptors, the activation thresholds for different current types were assessed in a larger sample of neurons (Fig. 4c).
For analysis of LTS bursts, we again had to use a smaller sample of neurons (10 BZ and 10 CZ neurons), for which we had long data files (duration of >350 s) that contained >150 LTS bursts.
For accurate circular statistics, we used a smaller sample of neurons (10 BZ and 10 CZ neurons), for which we had longer data files (duration of >350 s) containing >60 non-LTS spikes.
First, we analyzed an arbitrary sample of neurons, ignoring their laminar positions and their anatomical connectivity.
A sample of approximately 250 neurons per hemisphere in each of 6 mice per treatment group was analyzed and the percentage of striatal neurons containing NIIs was calculated.
In these experiments the depths of the cell bodies of a sample of CTb-labelled neurons were determined by examining all cells of this type in one section from the central part of the dorsal horn in each animal.
In a sample of nine basal forebrain cholinergic neurons, the mean dendritic arbor lengths were 9.6 mm at P12 (n = 5 arbors) and 11.5 mm at P30 (n = 4 arbors; Figure 2 figure supplement 1).
