Postsynaptic potentials in toad's spinal motoneurons due to muscle afferent volleys.
Although some investigators are dubious of a direct connection between the dorsal root fibers and the motoneurons in frog spinal cord21), evidences for the monosynaptic connection between them have recently been presented by ARAKI3), BROOKHART and FADIGA7)and FADIGA and BROOKHART16) with toad's and frog's spinal cord. In their experiments a single orthodromic stimulus delivered to a dorsal root...
متن کاملCharacteristics and mechanisms of locomotion induced by intraspinal microstimulation and dorsal root stimulation in spinal cats.
Intraspinal microstimulation (ISMS) through a single microelectrode can induce locomotion in cats spinalized at T(13) 1 wk before (untrained) or after 3-5 wk of treadmill training. Here we study the optimal parameters of ISMS and the characteristics of locomotion evoked. ISMS was applied in the dorsal region of segments L(3)-S(1) at different lateralities (midline to 2.5 mm) and after an intrav...
متن کاملVentral root afferent and dorsal root efferent fibres in dog and human lower sacral nerve roots.
Two pairs of wire electrodes were used to record single afferent action potentials from ventral roots and single efferent action potentials from dorsal roots of dogs and humans. A human lower sacral ventral root contained about 20 to 30% afferents among fibres with a diameter larger than 5 microns; a comparable ventral root of a dog contained about 1% afferents. Human S3, S4 and S5 dorsal roots...
متن کاملMuscarinic signaling in the cochlea: presynaptic and postsynaptic effects on efferent feedback and afferent excitability.
Acetylcholine is the major neurotransmitter of the olivocochlear efferent system, which provides feedback to cochlear hair cells and sensory neurons. To study the role of cochlear muscarinic receptors, we studied receptor localization with immunohistochemistry and reverse transcription-PCR and measured olivocochlear function, cochlear responses, and histopathology in mice with targeted deletion...
متن کاملIntraspinal latency, cutaneous fiber composition, and afferent control of the dorsal root reflex in cat.
The dorsal root reflex (DRR) is a special manifestation of primary afferent interaction which can be used to further examine and extend our understanding of cutaneous fiber interactions derived from studies of the dorsal root potential (DRP) and intracellular recording of primary afferent depolarization (PAD). The presynaptic interactions of mammalian cutaneous afferents, for example, are thoug...
