The slow speed of spikes (they travel about one foot per second in axons that lack the insulating sheathing called myelin) is one hundred - millionth the speed
of signal transmission in digital computers.
Hiroshima University, the National Institute of Information and Communications Technology, and Panasonic Corporation announced the development of a terahertz (THz) transmitter capable
of signal transmission at a per - channel data rate of over ten gigabits per second over multiple channels at around 300 GHz.
Congenital myasthenic syndromes (CMSs) are heterogeneous neuromuscular disorders characterized by skeletal muscle weakness caused by
disruption of signal transmission across the neuromuscular junction (NMJ).
They were able to demonstrate that both the speed and
frequency of signal transmission in the trapezoid body doubles as soon as the young mice begin to perceive sounds.
«Such losses are particularly critical in the auditory system, because they reduce the temporal
precision of signal transmission — and the quality of our perception of the acoustic environment is primarily dependent on rates of action potential generation and precise neural computation of their temporal sequences.»
Oligodendrocytes, the cells that are known to produce the myelin sheaths which enable saltatory conduction of action potentials along the myelinated axons, are
modulators of signal transmission along neuronal connections (axons) and also promote neuronal survival by providing metabolic support.
Because of the high speed of light, it is necessary that the
instant of signal transmission at the satellite and the instant of signal reception at the receivers antenna be accurately registered in order for the distance and, consequently, the position calculation to be accurate.
These gaseous messenger substances do not follow the normal
route of signal transmission via the synaptic cleft but can diffuse directly across the membrane of neighboring nerve cells without docking to receptors.
However, the low levels of acetylcholine seen during slow - wave sleep are necessary for lifting this
suppression of signal transmission in order to facilitate the consolidation of memories encoded during the waking hours.
Disruption
of signal transmission within the NMJ resulting from presynaptic, synaptic, or post-synaptic defects causes congenital myasthenic syndromes (CMSs), heterogeneous neuromuscular disorders characterized by skeletal muscle weakness and fatigue.
An Ludwig - Maximilians - Universitaet (LMU) in Munich study reveals that sound - evoked activity of neurons in the auditory system of the mouse increases the thickness of their myelin sheaths — and enhances the
speed of signal transmission — both during development and in the adult brain.
This could overcome the loss of
some of the signal transmission strength.
