Brain organoids — also called mini-brains — are 3D cellular models that represent aspects of the human brain in the laboratory. Brain organoids help researchers track human development, unravel the ...

Reentry arrhythmia occurs when electrical signals in the heart deviate from their usual path, creating a loop that causes repeated stimulation and disrupts the heart’s rhythm. Symptoms of reentry ...

People with third degree heart block have an irregular heartbeat due to a total blockage of the electrical impulses that control the heart’s activity. It can lead to faintness and breathing difficulty ...

Neuronal electrical activity correlates in a systematic way with these state changes. The most conspicuous of these activity measures exist in terms of nerve impulse firing and the extracellular ionic ...

Researcher have uncovered a new cell type in the human brain that fires electrical impulses. The cells are hybrids, part neuron and part glia, and are present in both glioma, a type of brain tumor, ...
