While the neural architecture responsible for the transmission of electrical impulses has been known for more than a century, the basic biology behind how a neuron acquires its one and only axon ...

The axons and dendrites of neuronal cells differ from each other in the composition of their proteins and organelles. Axons are typically long and thin, with a uniform width, and they branch at ...

Neuron Function Synapses Neural synapses are junctions between neurons that permit neural communication. Synapses come in two different forms: chemical and electrical. 2 Chemical synapses communicate ...

While comparing neurons and transistors is a convenient metaphor (and not completely out of left field), the brain is ...

Without key extracellular protein, neuronal axons break and synaptic connections fall apart Peer-Reviewed Publication. Picower Institute at MIT ...

Some are excitatory, pushing the neuron to fire; others are inhibitory, restraining the neuron from firing. Neurons with axons that have been truncated show a disruption of the normal excitatory ...

The semaphorins have integral roles in various processes that underlie the development of neural circuits. In this article, Jeroen Pasterkamp explores novel aspects of neuronal semaphorin receptor ...

In a study published in Cell on July 10, researchers reported the first comprehensive study of whole-brain projectomes of the macaque prefrontal cortex (PFC) at the single-neuron level and revealed ...

Researchers also tested the effects of lipin1 elimination on neuronal lipid metabolism to explore which components affect axon regeneration. Their measurements showed the following: cholesterol ...

Axon growth stops as the neuron and its axon connect to the neural circuit. "PTBP2 and SHTN1 give us an entry point to understand how splicing changes occur to promote axon growth," Zheng said.

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal ...
