... necessary for APP cleavage, BACE. Synaptic activity is known to involve a very different type of ... in vesicle trafficking and exocytosis. Also unclear is why neuronal activity should cause APP to jump ...
... at many different anatomical locations across the hippocampus, we found instead a systematic delay in neuronal activity from site to site. Instead of the whole structure oscillating at once, we see ...
... at Indiana University and the University of Montreal models the random synchronization of neuron activation. The findings expand scientists' understanding of brain rhythms, both reoccurring and ...
... . Under these conditions and although animals were exposed to identical stimuli, convergent neurons were not activated.
Bernstein and her colleagues also proposed a model that associative learning ...
... . They report their findings in Journal of Neuroscience, on Dec 17, 2008. They investigated neuronal activity in the basal ganglia of a dystonia mouse model, which was generated by transferring human ...
... neurons and further suggest the feasibility of using these cells to explore how changes in motor neuron activity contributes to the degeneration of these cells underlying these disorders," the authors ...
... promptly shift their cognitive sets and compared neuronal activity during shift and non-shift ... study provide unprecedented evidence that PPC neurons contribute to flexible shifting of internal cognitive ...
... a series of experiments using a neuroimaging technique that allowed very sensitive examination of neuronal activity. Subjects were imaged while performing reading detection tasks using real words and ...
... are firing, according to researchers at the Duke University Medical Center. "We speculate that the neurons' activity may lie beneath critical social behavior, such as joint attention," said Michael ...
... function via correlation. If a group of neurons activates every time an animal performs a certain ... key to the scientists' success is an artificial, light-activated protein they developed a few years ago ...
... s work is the first experimental demonstration of this Time-keeping function using recordings of neuron activity.
The discovery opens the door to many investigations, including how the brain produces ...
... They then developed a model that enabled them to test hypotheses about the relationship between neuronal activity that they measured in the animals’ motor cortex and the resulting actions.
They said ...
... explains.
“Reciprocally, the connections in the network determine the patterns of spontaneous neuronal activity and their complexity.”
“The calculations and the computer model showed that these ...

... , we show that knocking out MEFC2 in the brain results in mice with smaller brains, fewer neurons and reduced neuronal activity. The commonality is the protein's association in making new neurons."
