Kinetics, Ca2+ Dependence, and Biophysical Properties of Integrin-Mediated Mechanical Modulation of Transmitter Release from Frog Motor Nerve Terminals
Neurotransmitter release from frog motor nerve terminals is strongly modulated by change in muscle length. Over the physiological range, there is an ∼10% increase in spontaneous and evoked releaseExpand

Echolocation, development, and vocal communication in the lesser bulldog bat, Noctilio albiventris
SummaryForaging and echolocation behavior and its ontogeny in the lesser bulldog bat, Noctilio albiventris, were studied in Panama under field and captive conditions. The vocalizations utilized forExpand

Electrophysiological studies of central auditory mechanisms in cetaceans
Summary1.A preparation has been developed for the study of central auditory neurophysiology in cetaceans. Under N2O and Fluothane anesthesia, supplemented by succinylcholine chloride, twenty-nineExpand

Fishing and echolocation behavior of the greater bulldog bat, Noctilio leporinus, in the field
When hunting for fish Noctilio leporinus uses several strategies. In high search flight it flies within 20–50 cm of the water surface and emits groups of two to four echolocation signals, alwaysExpand

Direct Measurements of Presynaptic Calcium and Calcium-Activated Potassium Currents Regulating Neurotransmitter Release at CulturedXenopus Nerve–Muscle Synapses
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 monitoredExpand

Tracking presynaptic Ca2+ dynamics during neurotransmitter release with Ca2+-activated K+ channels
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 toExpand

Hypertonic enhancement of transmitter release from frog motor nerve terminals: Ca2+ independence and role of integrins
1 Hyperosmotic solutions cause markedly enhanced spontaneous quantal release of neurotransmitter from many nerve terminals. The mechanism of this enhancement is unknown. We have investigated thisExpand
