In this way, gap junctions provide metabolic and electrical coupling between cells. For example, cardiac tissue has extensive gap junctions, and the rapid movement of ions through these junctions ...

Gap junctions (yellow) are clusters of channels that form tunnels of aqueous connectivity between cells.

An electrical impulse cannot directly cross the gap so a different mechanism has to be used. Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent ...

Deep brain stimulation may provide immediate improvement in arm and hand strength and function weakened by traumatic brain injury or stroke, University of Pittsburgh School of Medicine researchers ...

During normal exercise, the output voltage was about 2.3 V, showing that the BioES-suture can effectively convert natural body movements into stable electrical impulses. To assess the BioES-suture’s ...

These receive incoming impulses from other neurones. Receptor cells detect a change in the environmental (a stimulus) and start electrical signals along neurons. These move towards the central ...

When the cells are triggered, it discharges an electrical impulse into the surrounding water.” It was by studying the electric eel that Italian scientist Alessandro Volta was able to invent the first ...

These organs take up about 80% of the eel’s body and allow them to produce electric impulses of different strengths, which ...

Your brain contains billions of nerve cells called neurons that communicate with each other by sending and receiving electrical impulses. A seizure occurs when there is sudden abnormal electrical ...

In women, researchers identified an association with longer QRS duration, or contraction of the ventricles, and dysfunction of the electrical impulses of the heart. "It was particularly pronounced ...

This pattern is then converted into electric impulses that are sent to a signal-processing unit. Within the signal-processing ...
