Light and gravity ensure that tree trunks grow straight up while their roots burrow deep underground. What about neurons, which can project up, down, and anywhere in between? What keeps the axon a ...

Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body, and axons carry signals away. In one of many surprise findings, ...

Nerve cells communicate by using electrical signals. Dendrites, the widely branched portion of the neuron, receive signals from other neurons and then transmit them over a thin cell extension -- the ...

The human brain is a network of nearly 100 billion neurons forming as many as a quadrillion synapses. Exactly how this massively distributed information processor produces and represents mental ...

In your typical brain cell, the branched dendrites receive electrical signals from other neurons, and once they’re processed, these signals are passed on to other neurons along the axon, a long ...

Glycogen synthase kinase-3β (GSK-3β), governs axon and dendrite growth in determining cell polarity, according to research groups from China and Japan. GSK-3β is found throughout neurons but is less ...

The cellular mechanisms underlying axogenesis and dendritogenesis are not completely understood. The axons and dendrites of retinal bipolar cells, which contact their synaptic partners within specific ...

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.
