Neurotransmitters in hiccups [PDF]
Hiccups are the sudden involuntary contractions of the diaphragm and intercostal muscles. They are generally benign and self-limited, however, in some cases they are chronic and debilitating. There are approximately 4000 admissions for hiccups each year in the United States.

Developmental Neurotransmitters? [PDF]
Previous studies support an early role for neurotransmitter signaling before synaptogenesis, but puzzlingly, a neurological phenotype is absent in embryonic mice that lack vesicular release. Demarque et al. (in this issue of Neuron) now report that early release of transmitter is unconventional in not requiring action potentials, Ca(2+) entry, or ...

Neurotransmitters and Neuromodulators [PDF]
In the central nervous system, besides the neurotransmitters, the occurrence of substances which modify neuronal excitability has been proposed. Since their effect is a matter of modulating neuronal responsiveness, these substances may be called neuromodulators.Examples of neurotransmitters or putative neurotransmitters in the central nervous system ...

A Life of Neurotransmitters [PDF]
Development of scientific creativity is often tied closely to mentorship. In my case, two years with Julius Axelrod, the sum total of my research training, was transformative. My mentoring generations of graduate students and postdoctoral fellows has been as nurturing for me as it has been for them.

SummaryStimulation of the cardioaccelerator nerve (CA) in the isolated chicken heart causes the release of norepinephrine and little epinephrine and increases heart rate significantly, but after beta blockade heart rate was depressed indicating the release of cholinergic agent which could be blocked with atropine.

Neurotransmitter release [PDF]
Axon terminals release more than one physiologically active substance. Synaptic messengers may be stored in two different types of vesicles. Small electron‐lucent vesicles mainly store classical low molecular weight transmitter substances and the larger electron‐dense granules store and release proteins and peptides.
