Cell death of motoneurons in the chick embryo spinal cord. IV. Evidence that a functional neuromuscular interaction is involved in the regulation of naturally occurring cell death and the
Embryos immobilized with neuromuscular blocking agents for differing periods between 4.5 and 9 days of incubation had an increased number of motoneurons in the brachial and lumbar lateral motorExpand

Ontogeny of spontaneous blinking and of habituation of the blink reflex
Habituation of the blink reflex to glabellar percussion was examined in 164 infants and children from ages 2 days to 18 years and in 18 adults aged 18 to 50 years. Spontaneous blink rates wereExpand

Developmental expression of the GABAA receptor alpha 1 subunit mRNA in the rat brain.
Recent studies have suggested that the GABAA, receptor complex, the site of action of the inhibitory neurotransmitter gamma amino-butyric acid (GABAA) and the anxiolytic benzodiazepines, isExpand

Localization of mesenteric hyperemia during digestion in dogs.
For localization of the site of post-prandial mesenteric hyperemia, low-fat, low-protein food was placed in either the stomach, duodenum, or jejunum while blood flow was measured in the celiacExpand

Embryonic behavior, hatching and neuromuscular development in the chick following a transient reduction of spontaneous motility and sensory input by neuromuscular blocking agents
Embryos were immobilized with neuromuscular blocking agents for one to four days between days 10 and 15 of incubation. This treatment reduces spontaneous motility, as well as movement‐initiatedExpand

Age-related electrophysiological changes in rat cerebellum
The spontaneous discharge of cerebellar Purkinje neurons was studied in 3-, 12-, 15-, and 20-month-old rats. Fluphenazine and haloperidol administered intraperitoneally produced a dose-dependentExpand

Expression of the beta subunit of chorionic gonadotropin in transgenic mice.
Transcriptional activation of the chorionic gonadotropin (CG) genes is linked to trophoblast differentiation. In a multistep process, cytotrophoblasts expressing only the alpha subunit differentiateExpand

Experimental studies on hatching behavior in the chick. IV. Evidence for the role of a noradrenergic mechanism.
In the present experiments we have attempted to determine whether one or more of the biogenic amines are involved in the prehatching and hatching behavior of the chick. Injection of reserpine firstExpand
