Antennal motor activity of the honeybee was used to test the effects of sucrose stimuli and of serotonin and octopamine microinjections into the brain. The antennal scanning behavior was analyzed in behavioral experiments. Activity of an antennal muscle, the "fast pedicellus flexor muscle" which dominates scanning behavior, was used as a physiological(More)
Honeybees fixed in small tubes scan an object within the range of the antennae by touching it briefly and frequently. In our experiments the animals were able to scan an object for several minutes with the antennae. After moving the object out of the range of the antennae, the animals showed antennal movements for several minutes that were correlated with(More)
Antennal movements of the honey bee can be conditioned operantly under laboratory conditions. Using this behavioural paradigm we have developed a preparation in which the activity of a single antennal muscle has been operantly conditioned. This muscle, the fast flagellum flexor muscle, is innervated by an identified motoneuron whose action potentials(More)
BACKGROUND Epidural anesthesia is commonly administered to laboring women. Some studies have suggested that epidural anesthesia might inhibit breast-feeding. This study explores the association between labor epidural anesthesia and early breast-feeding success. METHODS Standardized records of mother-baby dyads representing 115 consecutive healthy,(More)
