Working with patients with electrodes implanted in their brains, researchers show that areas of the brain work simultaneously to recall memories. The approach promises new insights into how we remember details of time and place.
Using several neuroimaging methods, a team of researchers working at the University of Western Ontario have now uncovered that functional changes within a key brain network occur directly after a 30-minute session of noninvasive, neural-based training.
Researchers found that neurons team up together to sway particular outcomes in the brain and take over the nervous system in the name of their preferred action or behavior.
A new information-theoretical model of human sensory perception and memory sheds light on some peculiarities of the nervous system. Ask adults from the industrialized world what number is halfway between 1 and 9, and most will say 5. But pose the same question to small children, or people living in some traditional societies, and they're likely to answer 3.
Proof of concept: Researchers identify principles to support brain simulation models. Blue Brain Project has identified key principles that determine synapse-scale connectivity by virtually reconstructing a cortical microcircuit and comparing it to a mammalian sample. These principles now make it possible to predict the locations of synapses in the neocortex.
Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.
Research from Washington University in St. Louis suggests that another 10 percent of individual differences in intelligence can be explained by the strength of neural pathways connecting the left lateral prefrontal cortex to the rest of the brain.
Researchers determined how the neurons and muscles are connected in a decision-making neural network important for mating in C. elegans. The team also accurately measured the weights of those connections, i.e., an estimate of the strength with which one neuron or muscle communicates with another.
New findings support the view that the content of consciousness is not localised in a unique cortical area. Consciousness is...
