Source: Taube, W., et.al., Non-invasive Assessment of Changes in Corticomotoneuronal Transmission in Humans. J. Vis. Exp. (2017)This video demonstrates a non-invasive method to assess changes in corticomotoneuronal transmission in humans following repetitive transcranial magnetic stimulation (rTMS). The study introduces an electrophysiological technique that differentiates fast, direct corticospinal pathways from polysynaptic connections.

A reliable home-based way to assess the language comprehension of very young typically developing children, as well as those with autism, is described. The method analyzes children's eye gaze while viewing side-by-side images but hearing an audio that matches only one image. Stimuli are designed with young participants in mind.

2025
The video demonstrates long-term continuous electroencephalography (EEG) monitoring in rodent pups using a wireless transmitter system. The transmitter contains two recording electrodes and one reference electrode extending to the brain's surface. Upon placing the pup in a recording chamber, EEG can be continuously monitored throughout the pup's development into adulthood.

The Synapse

Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information. An electrical synapse is one type of synapse in which the pre-...

2025
This video demonstrates a method for measuring pain-evoked brain activity in infants. It outlines the procedure for positioning electrodes on the infant's head and applying pain stimuli to the infant's hand using a flat-tip probe. The video also shows the EEG recording process to identify brain activity in response to the stimuli.
FAQs
At the sending end, processing is organized as a signal chain. Encoding prepares the information for transmission, modulation places it into a suitable signal form, amplification raises signal strength, and filtering controls the signal content. These operations are coordinated rather than treated as isolated steps because each affects how efficiently the next stage operates. The resulting design influences bandwidth use and signal quality.
Encoding and modulation perform different tasks within the transmission process. Encoding prepares the original voice, data, or sensor information in a form suitable for communication, while modulation transfers that prepared information onto an electrical, optical, or radio-frequency signal. Separating these functions helps engineers organize how information is represented and how it is carried through the communication channel.
Amplification increases the strength of the signal before it enters the channel. This matters because signal strength contributes to transmission range and the ability to preserve signal quality during transfer. However, amplification is one part of a larger source-side design: filtering and the selected signal form also influence bandwidth use and resistance to interference, so strength alone does not determine link performance.
Filtering controls the content of the transmitted signal before it reaches the channel. By shaping what is sent, it supports more efficient bandwidth use and can contribute to resistance to interference. In engineering designs, filtering therefore works alongside encoding, modulation, and amplification rather than replacing them. Its importance becomes especially clear when signal quality and reliable information transfer are design priorities.
A typical source-side sequence begins with the information to be transferred, such as voice, data, or a sensor signal. The system then encodes the information, modulates it into an electrical, optical, or radio-frequency signal, amplifies it, and applies filtering before transmission through the channel. This sequence gives engineers a structured way to connect message preparation with range, bandwidth, and quality requirements.
These principles support wired and wireless networks, telemetry systems, digital communication links, and other technologies that transfer information. The source-side design must be matched to the intended communication setting because electrical, optical, and radio-frequency signals provide different transmission forms. Engineers use the resulting signal-processing choices to address practical goals such as transmission range, bandwidth use, signal quality, and resistance to interference.
