Were the subjects trying to please the researchers? Were the researchers who elicited "Detection" and "Awareness" unaware of whether stimuli had been delivered, and, if unaware, were they tested for their awareness through forced choice guesses? Did medication alter thresholds? Why was electroencephalography not used as an objective measure of detection and, or awareness?

With reference to trying not to find what they were looking for, the researchers stated that: "The IPSCs were always substantially larger than spontaneous IPSCs, if present, and were evoked with a constant latency typically between 50 and 100msec relative to the frequency of the glutamate pulse." Why was the difference in amplitude between evoked and spontaneous IPSCs not tested for statistical significance? Why was the rate of spontaneous IPSCs not reported? Why were there no images enabling comparisons of evoked and spontaneous IPSCs?
With reference to changes in tense, the researchers used the present tense unequivocally in the discussion, thereby generalising their findings in spite of the limitations of the in vitro format, which they did not acknowledge.

With reference to hyperbole, the opening sentence of the abstract: "The main role of the thalamus is to relay sensory inputs to the neocortex." is provocative. The thalamus orchestrates sensory, motor and visceral activities, as evidenced by its many nuclei, and if the researcher believed that these activities could be ranked, then he should have presented evidence to support his view.
With reference to trying not to find what he was looking for, the researcher's results for acetylcholine included p<0.0001; n=3 and for norepinephrine p<0.0001; n=4, which findings were described in the present tense as having general application. The similarity of effects of acetylcholine and norepinephrine suggested that they might have been due to the experimental format, which the researcher did not discuss.

With reference to animal experimentation, were the procedures to which the guinea pigs were subjected approved ethically?
With reference to consistent language: "Four of the five neurons located in the ventral division of the MGB (MGv) received facilitatory modulation from the cortical stimulation and the remainder did not respond to the cortical stimulation." Why not just say that one neurone did not respond? Again: "Of the four neurons that were histologically confirmed to be in the non-lemniscal MGB, three showed an inhibitory response to the acoustic stimulus, and one responded with spikes and EPSPs to the auditory stimulus." What was the difference between the acoustic stimulus and the auditory stimulus?
With reference to conclusions extending beyond results, the distinction between the "lemniscal" and "non-lemniscal" MGB was based on a sample of nine neurones, but the researchers do not indicate from how many guinea pigs these nine neurones were derived.

With reference to incorrect punctuation: "In contrast to this, relatively high degree of task specificity, in both VPLo and VLo the largest group of cells (approximately 55%) burst in relation to both tasks." There should be no comma after "this", and there should be a comma after VLo, and these mistakes visually trigger uncertainty.
With reference to the use of a singular noun with a plural verb, below Fig. 4. in the main text "...the largest group of cells were active" appears twice.

With reference to the lack of controls, and to how hard the researchers tried not to find what they were looking for, these researchers did not use control injections of lignocaine 5% into other thalamic nuclei, in spite of the realisation that the injected lignocaine might spread.
With reference to wishes conveyed by italics, specific subcircuits appeared for the first time in the discussion, as the concerns about the spread of lignocaine 5% were being admitted.
