Purkinje cells, the primary output neurons in the cerebellum, have the ability to modulate and filter incoming signals, according to research from Kyoto University[1]. The findings shed new light on learning mechanisms of both the cerebellum and the brain. The cerebellum is a structure located at the base of the brain, and is known to… Read more

During decision-making, neurons in the brain are capable of much more complex processing than previously thought, new research indicates. The findings[1] show that during decision-making, there are a multitude of small sections of dendrite throughout each neuron that process information before it is sent to other neurons. This suggests that much more complex processing can… Read more

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… Read more

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… Read more

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… Read more
