Web12 de abr. de 2024 · In fact, travelling waves in the cortex are usually observed not at the whole-brain level but localized in smaller regions [5, 75, 76]. A reconciling approach could consist on applying the same analysis in a model closer to experimental conditions, based on short-range coupled NMMs in a small section of the cortex. Web12 de dez. de 2024 · Answer: Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. …
Web26 de abr. de 2011 · When the signal reaches the end of an axon, it causes the release of chemical neurotransmitters into the synapse, a chemical junction between the axon tip and target neurons. A target neuron responds with its own electrical signal, which, in turn, spreads to other neurons. WebFor functional interpretations of brain oscillations in the visual system, it therefore seems to be crucial to find out whether or not the phase of brain oscillations can be affected by visual stimuli. To answer this question, we investigated whether alpha waves are generated by a linear or a nonlinear mechanism.
