Migraine and its transformation to chronic migraine are immense healthcare burdens in need of improved treatment options. We seek to define how neural immune signaling modulates the susceptibility to migraine, modeled in vitro using spreading depression in hippocampal slice cultures, as a means to develop novel therapeutic targets.

Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut An electrocardiograph is a graph recorded by electric potential changes occurring between electrodes placed on a patient's torso to demonstrate cardiac activity. An ECG signal tracks heart rhythm and many cardiac diseases, such as poor blood flow to the heart and structural abnormalities. The action potential created by contractions of the heart wall...

An approach for analyzing migration and eventual fate of avian neural crest cells in quail-chick chimeric embryos is described. This method is a simple and straightforward technique for tracing neural crest cells during migration and differentiation that are otherwise difficult to distinguish within an unmanipulated chick embryo.

Small-Signal Analysis of MOSFET Amplifiers

In small-signal analysis, a MOSFET transistor amplifier acts as a linear amplifier when operating in its saturation region. The gate-to-source voltage (VGS) of the MOSFET is the sum of the DC biasing voltage and the small time-varying input signal. This combination sets up the operating point and modulates the drain current (ID) that flows from the drain to the source. When a small AC signal is superimposed on the DC bias voltage at the gate, the instantaneous drain current comprises three...
FAQs
Membrane-potential changes reveal shifts in a neuron's electrical state, while action potentials represent electrical events that can transmit information along neural pathways. Examining these signals helps investigators characterize how neurons generate and propagate activity. Comparing signal patterns across conditions can support mechanistic models of normal nervous system function and identify alterations associated with dysfunction.
Neurotransmitter release provides a chemical step in communication between neurons. Its analysis complements measurements of electrical activity by showing how one cell influences another across a synapse. This distinction helps researchers evaluate communication at both individual-cell and circuit levels, which is important for understanding connectivity, information processing, and changes in neuronal communication linked to disease.
The analysis considers electrical events, including membrane-potential changes and action potentials, separately from chemical signaling through neurotransmitter release. Evaluating both forms of communication gives a more complete view than focusing on either alone. This combined perspective helps relate neuronal activity to synaptic interactions and supports explanations of how nervous system circuits process and transmit information.
Changes in measured or manipulated neural signals can indicate abnormalities in neuronal communication, although their interpretation depends on the electrical or chemical process being examined. By relating altered activity to synaptic communication and circuit behavior, researchers can investigate mechanisms of neurological disease. These findings may also guide diagnostic strategies and treatments aimed at abnormal signaling.
A typical analysis identifies the signaling process of interest, measures or manipulates the relevant neural activity, and examines the resulting electrical or chemical signals. Researchers then relate those observations to synaptic communication, circuit connectivity, or functional behavior such as sensory processing and motor control. The resulting patterns can be used to build or test mechanistic models.
Researchers apply this approach when they need to connect neuronal communication with a functional process. For example, examining signaling can help characterize circuit connectivity, sensory processing, or motor control. Because the approach addresses both electrical activity and chemical synaptic communication, it can link cellular events to broader nervous system operations rather than treating circuit behavior as an isolated outcome.
Measurements can describe how neural activity changes, while manipulations can help examine how those changes influence communication or circuit function. Together, these approaches provide evidence about neuronal signaling, synaptic interactions, and network organization. Their results can support mechanistic models and help identify signaling patterns relevant to diagnosis or treatment development in neurological disease.
