In this procedure, a comparison is made between the responding elicited by individual versus compound presentations of two extinguished CSs.
For liquid stimuli, cotton applicators (Puritan Medical Products, Guilford, ME, USA) were saturated with the pure compound before presentation to the animal.
Such an inclusion would have clarified whether patients have a general deficit in learning under conditions of confusion between single and compound stimulus presentation.
During the second phase, the lever was available throughout the whole session and an elevation score was calculated for each stimulus as the mean number of responses during each component or compound stimulus presentation minus the mean number of responses during the 30-s prestimulus interval for that specific stimulus.
During the actual test (Phase 3, parts 2 and 3), the EF compound was presented twice, unreinforced, followed by four unreinforced presentations of the components E and F, intermixed with four unreinforced presentations of the compound EF.
A few patients, either with typical or atypical clinical presentation, are compound heterozygous for the GAA expansion and a micromutation.
In the second part, participants first received two presentations of the new compound EF, followed by another four presentations of EF intermixed with four presentations each of E and F. The trial-level raw data are archived at www.willslab.co.uk/kulmaes2 with md5 checksum 931a93e8e924c7d5116043680b30cd65.
The data presented strongly support the charcoal presentation as a compound heterozygote (A Pbe /a) of the leopard cat agouti allele (A Pbe ) and the domestic cat non-agouti melanism allele (a).
Automatically generated HTML, PDF and ASCII presentations of compound sets are identified by their set number.
The tool Show Absent/Present Compounds reveals a tabular presentation of pie charts, which shows in how many chromatograms of a particular chromatogram group or the entire experiment a particular compound was identified (cmp. Fig. 3a).
