...Michelle C. Stone; Gregory O. Kothe; Melissa M. Rolls; Timothy Jegla ABSTRACT The centralized nervous systems of bilaterian animals rely on directional signaling facilitated by polarized neurons with specialized axons and dendrites. It is not known whether axo-dendritic polarity is exclusive...

...Melissa M. Rolls; Timothy J. Jegla; Peter A. V. Anderson Polarized distribution of signaling molecules to axons and dendrites facilitates directional information flow in complex vertebrate nervous systems. The topic we address here is when the key aspects of neuronal polarity evolved. All neurons...

... flagellum, the axonal conduction velocity of the sensory neuron pair associated with each feathered sensillum was linearly related to the position of the sensillum along the flagellar axis. In the current studies I show that the conduction velocity of axons within the proximal three segments...

...Sergej V. Shabelnikov; Olga A. Bystrova; Vadim A. Ivanov; Boris A. Margulis; Marina Martynova SUMMARY The atrium of the gastropod mollusc Achatina fulica receives rich innervation and contains numerous granular cells (GCs). We studied the atrial innervation and discovered that axon profiles typical...

...I. Parnas; O. Shahrabany-Baranes; N. Feinstein; P. Grant; H. Adelsberger; J. Dudel ABSTRACT Peripheral axons of lobsters can survive for many months after axotomy. We have investigated the structural and ultrastructural changes seen after axotomy using confocal microscopy and electron microscopy...

... that propagate at approximately 50cms −1 . The identity of the giant axons activated by tubefoot stimulation, the path-ways they follow and their role in mobilizing the coordinated escape response are discussed. 24 09 1986 Suction electrodes for recording were either polyethylene or glass...

...Philip J. Stephens; Paul A. Frascella; Norman Mindrebo ABSTRACT In autotomized walking limbs of Pachygrapsus crassipes , microelectrode recordings of evoked action potentials were made in the meropodite from the E2 excitor axon to the bender muscle. The action potential spike was followed...
