The original nerve impulse findings were that the rate of impulse firing governed the impact on neuronal targets, whether they be muscle or other neurons. Various labs, including my own, in the 1980s, ...

ITHACA, N.Y. -- Combining the bright laser light of multiphoton microscopy with specially developed dyes and a phenomenon called second-harmonic generation, biophysicists at Cornell University and ...

(1) A nerve impulse arrives. (2) This causes calcium ion channels to open, resulting in an influx of calcium ions in the terminal. (3) This causes synaptic vesicles to fuse with the terminal membrane, ...

Researchers developed a laser-based artificial neuron that fully emulates the functions, dynamics and information processing of a biological graded neuron, which could lead to new breakthroughs in ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...

Neurons, also known as nerve cells, send and receive signals throughout your nervous system. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique.
