New study by David Freedman, PhD and Bobby Kasthuri, PhD from finds that, surprisingly, primate neurons have fewer synapses than mice in the visual cortex.
By studying several neuron pairs that innervate distinct muscles in a fruit fly model, researchers found that some neurons compensate for the loss of a neighboring partner.
Proteins active in a neuron’s development can have powerful roles in its maintenance later: a “temporal modularity,” where proteins take on multiple roles at different times in a cell’s life.
How do our brains translate the signals of millions of neurons into meaningful perceptions of our environment and help guide our behavior? Attempting to answer this question is no small task, but understanding the connection between spiking neurons and our behavior will not only provide insights into the human brain but also will be the key for developing new and innovative neuroprosthetic devices.
Among the most prominent goals of UChicago’s Neuroscience Institute is to make a major contribution to the understanding of neural circuits—how information is processed by networks of neurons. But experimentation to understand neural circuitry is costly and complicated, in several ways.
