A Clock-Like Neuron That Predicts Perception By Rhythmicity

Interneurons
A new type of cell that keeps time so regularly that it may serve as the brain's long-hypothesized clock or metronome has been identified by Brown University neuroscientists. This type of neuron spikes rhythmically, and in a synchronized manner, independent of external sensations, said Chris Moore, a professor of neuroscience at Brown and the associate …

Perception Is Fundamentally Linked To Visual Working Memory

perception and working memory
Perception and thought are fundamentally linked, according to research from George Washington University. "We create a false separation between our perception of the world and the way that we're thinking about it. But actually these two things occur at the same time, in the same place, and as a result they interfere with each other. …

Neuroscience And Artificial Intelligence Can Help Improve Each Other

neuron interconnections
Despite their names, artificial intelligence technologies and their component systems, such as artificial neural networks, don’t have much to do with real brain science. I’m a professor of bioengineering and neurosciences interested in understanding how the brain works as a system – and how we can use that knowledge to design and engineer new machine …

Neural Computation Relies On Compartmentalized Dendrites To Discern Inputs

Electrical Compartmentalization in Neurons
Researchers at EPFL's Blue Brain Project have discovered that dendrites, the neuron's tree-like receptors, work together — dynamically and depending on the workload — for learning. The findings further our understanding of how we think and may inspire new algorithms for artificial intelligence. The analysis was performed using cells from the Blue Brain's virtual rodent …

Constricting Actin Spheres Accelerate Injured Axons Disintegration

actin spheres
The same mechanism by which damaged peripheral nerves can regenerate after an injury could be activated in cells of the central nervous system – after a spinal cord injury, for instance, new research indicates. "An injury in the peripheral nervous system quickly triggers the activation of a fascinating repair process that allows the injured nerve …
