Neural Computation Relies On Compartmentalized Dendrites To Discern Inputs

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 […]

Dendrites Are Unexpectedly Active In Neural Computation

Most neurons have many branching extensions called dendrites that receive input from thousands of other neurons. Dendrites aren’t just passive information-carriers, however. According to a new study from MIT, they appear to play a surprisingly large role in neurons’ ability to translate incoming signals into electrical activity. Neuroscientists had previously suspected that dendrites might be […]

Inhibitory Synapse Growth Is Stimulated In The Vicinity Of Excitatory Synapses

The growth of inhibitory synapses is specifically stimulated in the vicinity of excitatory synapses, researchers at Utrecht University have discovered. The vast majority of synapses are excitatory, which increase the activity of the receiving neuron. Around 10 to 20 percent of synapses have the opposite effect, and are called inhibitory. “Excitatory and inhibitory synapses create […]

Neocortical Thickness Governs Dendritic Morphology Of Visual Cortex Neurons

The thickness of the brain’s outer layer influences how individual neurons process information, new work from the University of Queensland indicates. The findings challenge the understanding of how brain circuits function throughout the brain. The outer layer of the brain (the cortex), is made up of many smaller microcircuits of brain cells, each consisting of […]
