Retrograde labeling was combined with cytochemistry to investigate phenotypic differences in primary afferent neurons relaying sensory information from deep and superficial craniofacial tissues. Calcitonin gene-related peptide (CGRP), substance P (SP), somatostatin (SOM) immunoreactivity and isolectin IB4, and cholera toxin B (ChTB) binding were examined(More)
Contractions of the transmurally stimulated guinea-pig ileum were not affected by 10 microM bicuculline, a competitive GABAA receptor antagonist. The GABAA potentiator alphaxalone depressed the responses to 2 and 20 Hz stimulation by 20% and 40%, respectively, but had no effect on 0.2 Hz responses. The depressions were prevented by 10 microM bicuculline.(More)
