How do neurons communicate with each other? (a) What is the main function of the nervous system? (b) How does it accomplish its mission? (c) Describe the similarities and differences between the endocrine and neural systems. What are some general components of endocrine signaling? How ...
Neurons themselves are simple and perform basic mathematical functions to normalize their outputs between 1 and 0 or -1 and 1. They become powerful, however, when they’re connected to each other. Neurons are arranged in layers in a neural network and each neuron passes on values to the ...

Kandel's team found in a previous study that CPEB3 plays a critical role in strengthening synapses, the connection points where tiny branches of neurons connect to each other when all memories are made. When they prevented mice from making CPEB3, those animals could form a new memory but ...
Paracrine Signaling:This form of communication takes place between cells that are near each other, but are not connected. In this case, the cells talk via the diffusion of chemical signaling molecules across short distances.Synaptic signalingbetweenneurons(brain cells) is an example of paracrine sign...
Connect with a licensed therapist online Mirror neurons, empathy, and social behavior Mirror neurons are generally nerve cells located in the brain that light up both when you see someone performing an action and when you perform that action yourself. They may be related to empathy and other soc...
Neurons and blood vessels often traverse the body side by side, a fact observed as early as the 16th century by the Flemish anatomist Andreas Vesalius. Only over the last ten years, however, researchers have discovered that the growth of neuronal and vascular networks is controlled by the same...
Despite considerable progress, the complex molecular processes are still not fully understood. It is all the more astonishing how smoothly neurons communicate with each other and how effectively the fusion machinery works in the synapse to effect our every movement, emotion and thought. Scientists the...
from that of the remaining network. Information processing through hubs is characterized by theirrhythmic activitythat is synchronized to one another. This suggests that large groups of neurons synchronize rhythmically to connect parts of the brain together in order to solve specific tasks (eLife, ...
A hallmark of neurodegenerative diseases like Huntington's is the progressive death of nerve cells in the brain. The cells don't die quickly, though. They first start to disconnect from each other because their neurites—long finger-like extensions that
