Transmitter concentration at a three-dimensional synapse.
Transmitter concentration at a three-dimensional synapse. J. Neurophysiol. 80: 3163-3172, 1998. At intensities from starlight to 1000-fold brighter, the mammalian rod synapse transmits a binary signal, the capture of 0 or 1 photon. Zero is signified by tonic exocytosis, and 1 is signified by a brief pause. The synapse is three dimensional: vesicles discharge at the apex of a deep cleft created ...
متن کاملCalcium control of transmitter release at a cerebellar synapse
The manner in which presynaptic Ca2+ influx controls the release of neurotransmitter was investigated at the granule cell to Purkinje cell synapse in rat cerebellar slices. Excitatory postsynaptic currents were measured using whole-cell voltage clamp, and changes in presynaptic Ca2+ influx were determined with the Ca(2+)-sensitive dye furaptra. We manipulated presynaptic Ca2+ entry by altering ...
متن کاملTwo components of transmitter release at a central synapse.
After the arrival of a presynaptic nerve impulse at an excitatory synapse in hippocampal neurons, the rate of neurotransmitter release increases rapidly and then returns to low levels with a biphasic decay. The two kinetically distinct components are differentially affected when Sr2+ is substituted for Ca2+ ions. Our findings are comparable to those of the classical studies for the frog neuromu...
متن کاملCytosolic Transmitter Concentration Regulates Vesicle Cycling at Hippocampal GABAergic Terminals
Sustained synaptic transmission requires vesicle recycling and refilling with transmitter, two processes considered to proceed independently. Contrary to this assumption, we show here that depletion of cytosolic transmitter at GABAergic synapses reversibly reduces the number of recycling vesicles. Using paired recordings in hippocampal cultures, we show that repetitive activity causes two phase...
متن کاملCarbachol can be released at a cholinergic ganglionic synapse as a false transmitter.
Carbachol was injected into a presynaptic cholinergic neuron in the buccal ganglion of Aplysia and the quantal aspects of the Cl- -dependent postsynaptic response to a prolonged stimulation were analyzed by a statistical fluctuation method. The calculated amplitude of the miniature postsynaptic current was increased with respect to control. Statistical fluctuation analysis was also used to anal...
