Sy T, Grinnell A, Peskoff A, Yazejian B
Neuroscience
. 2009 Nov;
165(3):715-22.
PMID: 19897018
Neurotransmitter release from the basolateral surface of auditory and vestibular hair cells is mediated by Ca(2+) influx through voltage-gated Ca(2+) channels. Co-localization of large-conductance Ca(2+)-activated K(+) (BK) channels at the...

Sand O, Chen B, Grinnell A
J Physiol
. 2001 Oct;
536(Pt 1):21-33.
PMID: 11579154
1. Simultaneous pre- and postsynaptic patch recordings were obtained from the varicosity synapses formed by Xenopus motoneurons on muscle cells in embryonic cultures, in order to elucidate the contribution of...

Pattillo J, Yazejian B, DiGregorio D, Vergara J, Grinnell A, Meriney S
Neuroscience
. 2001 Feb;
102(1):229-40.
PMID: 11226687
Using Xenopus nerve-muscle co-cultures, we have examined the contribution of calcium-activated potassium (K(Ca)) channels to the regulation of transmitter release evoked by single action potentials. The presynaptic varicosities that form...

Kashani A, Chen B, Grinnell A
J Physiol
. 2001 Feb;
530(Pt 2):243-52.
PMID: 11208972
Hyperosmotic solutions cause markedly enhanced spontaneous quantal release of neurotransmitter from many nerve terminals. The mechanism of this enhancement is unknown. We have investigated this phenomenon at the frog neuromuscular...

Yazejian B, Sun X, Grinnell A
Nat Neurosci
. 2000 May;
3(6):566-71.
PMID: 10816312
Neurotransmitter release during action potentials is thought to require transient, localized [Ca2+]i as high as hundreds of micromolar near presynaptic release sites. Most experimental attempts to characterize the magnitude and...

Pawson P, Grinnell A, Wolowske B
J Neurocytol
. 1999 Jan;
27(5):379-91.
PMID: 9923982
Neurotransmitter release from different parts of frog motor nerve terminals is often non-uniform. There is a decrease in release efficacy from the distal regions of frog motor nerve terminal branches....

Pawson P, Grinnell A, Wolowske B
J Neurocytol
. 1999 Jan;
27(5):361-77.
PMID: 9923981
The orderly arrays of intramembranous particles (IMPs) found in the p-face of freeze-fracture replicas of the frog neuromuscular junction ('active zones') are believed to be involved in transmitter release. Some...

Yazejian B, DiGregorio D, Vergara J, Poage R, Meriney S, Grinnell A
J Neurosci
. 1997 May;
17(9):2990-3001.
PMID: 9096135
The understanding of neurotransmitter release at vertebrate synapses has been hampered by the paucity of preparations in which presynaptic ionic currents and postsynaptic responses can be monitored directly. We used...

Chen B, Grinnell A
J Neurosci
. 1997 Feb;
17(3):904-16.
PMID: 8994045
Neurotransmitter release from frog motor nerve terminals is strongly modulated by change in muscle length. Over the physiological range, there is an approximately 10% increase in spontaneous and evoked release...

Harada Y, Grinnell A
J Neurobiol
. 1996 Dec;
31(4):433-48.
PMID: 8951102
We investigated the motor unit organization and precision of reinnervation in the Xenopus pectoralis muscle following different manipulations, including crush or section of the posterior pectoralis nerve, foreign nerve innervation,...
