We demonstrate the transmission of multiple independent signals through a multimode fiber using wavefront shaping employing a single spatial light modulator. By modulating the wavefront for each signal individually, spatially separated foci are transmitted. Potential applications are multiplexed data transfer in communications engineering and endoscopic light delivery in biophotonics.

The aim of the present study was to assess changes in transmission at the corticomotoneuronal synapses in humans after repetitive transcranial magnetic stimulation. For this purpose, an electrophysiological method is introduced that allows assessment of pathway specific corticospinal transmission, i.e. differentiation of fast, direct corticospinal pathways from polysynaptic connections.

FAQs
An action potential follows a coordinated change in ion flow. Opening voltage-gated sodium channels allows sodium ions to enter the neuron, initiating the signal. Potassium then leaves the cell, helping restore the membrane potential. This ordered sequence converts a stimulus into an electrical event that can reach a synapse and continue neuronal communication.
Voltage-gated sodium and potassium channels give the electrical phase its ordered sequence: sodium entry initiates the action potential, whereas potassium efflux restores membrane potential afterward. Their distinct contributions allow investigators to separate signal initiation from recovery when examining neuronal responses to stimuli. This distinction also makes ion channels important targets in neurological research.
After an electrical signal reaches a synapse, it promotes neurotransmitter release. These chemical messengers bind receptors on a neighboring cell, transferring information from the signaling neuron to the receiving cell. Receptor binding links activity in one neuron to the next, helping neural circuits coordinate sensory processing, movement, and regulation of internal functions.
A biological investigation can focus on three linked targets: ion channels that shape electrical changes, synapses where communication becomes chemical, and neurotransmitter systems that support signaling between cells. Examining these components connects cellular events with larger neural functions and provides a framework for identifying where transmission may be altered in neurological disorders.
By connecting stimulus detection with communication between neurons, nerve signal transmission helps organize sensory processing and motor control. The same signaling framework also contributes to regulation of internal functions. In biology, tracing these links helps researchers relate cellular electrical and chemical events to the coordinated activities of neural circuits.
Transmission provides several points for investigating neurological disorders: ion channels generate electrical changes, synapses pass messages, and neurotransmitter systems support chemical communication. Treatments can be studied by asking how they affect these targets. This approach links cellular mechanisms to disorder research and supports the development of therapeutic strategies directed at specific parts of neural signaling.
