Neuromodulation of Axon Terminals.
Understanding which cellular compartments are influenced during neuromodulation underpins any rational effort to explain and optimize outcomes. Axon terminals have long been speculated to be sensitive to polarization, but experimentally informed models for CNS stimulation are lacking. We conducted simultaneous intracellular recording from the neuron soma and axon terminal (blebs) during extrace...
متن کاملHorizontal cell axon terminals in growing goldfish.
In the retina of teleost fish, cone horizontal cell axons penetrate the inner nuclear layer, where they enlarge into fusiform terminal swellings. The present study shows that horizontal cell axon terminals enlarge disproportionately during postembryonic growth of the retina in juvenile and adult goldfish: the relative volume of axon terminals increases almost 20-fold, while the volume of the en...
متن کاملDevelopment of Ocularity Domains and Growth Behaviour of Axon Terminals
Ontogenetic development of ocularity domains-stripes, patches and layers in cortex, colliculus superior and lateral geniculate nucleus-is the result of organization that may either be intrinsic to the postsynaptic structure or induced to it by the aaerents. A speciic type of axonal growth behaviour that was recently proposed as a basis for ontogenetic development of retinotopy is suucient to ac...
متن کاملTarget-controlled differentiation of axon terminals and synaptic organization.
These experiments investigate the processes regulating the morphological differentiation of synaptic connections. Electron microscopy showed that the terminal boutons and synaptic complexes of retinal afferent axons in the main thalamic visual nucleus, the dorsal lateral geniculate nucleus, differ in their morphology from those of ascending afferent axons in the main thalamic somatosensory (ven...
متن کاملControl of extracellular dopamine at dendrite and axon terminals.
Midbrain dopamine neurons release dopamine from both axons and dendrites. The mechanism underlying release at these different sites has been proposed to differ. This study used electrochemical and electrophysiological methods to compare the time course and calcium dependence of somatodendritic dopamine release in the ventral tegmental area (VTA) and substantia nigra pars compacta (SNc) to that ...
