Heterogeneity of membrane properties in sympathetic preganglionic neurons of 1 neonatal mice :
19 Spinal cord sympathetic preganglionic neurons (SPNs) integrate activity from descending 20 and sensory systems to determine the final central output of the sympathetic nervous system. 21 The intermediolateral column (IML) has the highest number and density of SPNs, and within 22 this region SPN somas are found in distinct clusters within thoracic and upper lumbar spinal 23 segments. While SP...
متن کاملPhysiological properties of newly formed synapses between sympathetic preganglionic neurons and sympathetic ganglion neurons.
We have examined the physiological properties of transmission at newly formed synapses between sympathetic preganglionic neurons and sympathetic ganglion neurons in vitro. Chick neurons were labeled with fluorescent carbocyanine dyes before they were placed into culture (Honig and Hume, 1986), and were studied by making intracellular recordings during the first 2 weeks of coculture. Evoked mono...
متن کاملInhibition of sympathetic preganglionic neurons by spinal glycinergic interneurons.
Intracellular and whole-cell patch-clamp recordings were obtained from sympathetic preganglionic neurons in rat spinal cord slices. Perfusion of selective ionotropic and metabotropic excitatory amino acid agonists induced depolarizing responses in all neurons. In approximately 20% of neurons the application of these agonists also evoked inhibitory postsynaptic potentials. The application of the...
متن کاملPutative transmitter systems of mammalian sympathetic preganglionic neurons.
The sympathetic nervous system evokes complex effects at multiple target organs in response to external, internal as well as mental stimuli. This output involves an interplay between the actions of a number of transmitters and modulators and at the postsynaptic and presynaptic sites of the autonomic ganglia and the sympathetic preganglionic neurons (SPNs). This review concerns particularly the ...
متن کاملHeterogeneity of membrane properties in sympathetic preganglionic neurons of neonatal mice: evidence of four subpopulations in the intermediolateral nucleus.
Spinal cord sympathetic preganglionic neurons (SPNs) integrate activity from descending and sensory systems to determine the final central output of the sympathetic nervous system. The intermediolateral column (IML) has the highest number and density of SPNs and, within this region, SPN somas are found in distinct clusters within thoracic and upper lumbar spinal segments. Whereas SPNs exhibit a...
