释义 | neuron noun[ C ] biology specializeduk /ˈnjʊə.rɒn/ us /ˈnʊr.ɑːn/(UK alsoneurone) a cell that carries information between the brain and other parts of the body: 神经元 Research has shown that aerobic exercise remodels the brain, prompting the growth of new neurons. Both of these act to decrease the excitability of the neurones. Lower motor neuron lesions produce weakness of the muscles supplied by the affected neurons. This finding shows that a specific combination of two molecules can block only pain-related neurons. The cells that carry these signals are called neurones.

This means that when one type of behavior is repeated, like being sociable, that tells the brain to produce more neurons, helping someone do that behavior better. What’s more, doing something like playing a musical instrument will make the brain grow more neurons in the area being used. neuron | American Dictionaryneuron noun[ C ] us/ˈnʊr·ɑn/ biology (in animals and people) a type of cell that sends and receives messages within the brain and the nerves of the body Examples of neuronneuron Stress, the aging brain, and the mechanisms of neuron death. This included neurons with anticipatory activity, "vigilance," and activity related to the reinforcing qualities of the reward itself. Therefore, during one cycle of fast oscillations only a small volume of neurons is recruited. These findings indicate that, under conditions of reduced astrocytic coverage of neurons, diffusion is facilitated and takes place in a reduced volume. Firing patterns of neurons in abducens nucleus and surrounding medulla and their relation to eye movements. The dashed line is the theoretical total nuclei assuming all neurons survive and astroglia start at zero. The spike trains of neurons in sensory systems are certainly correlated with the structure of sensory input. Each successive hidden neuron is trained on the component of the problem its predecessors failed to learn, that is, the remaining error. The activity of most thalamic neurons is reduced, not increased, during trains of high frequency pallidal stimulation. Patients suffering from progressive autonomic failure with primary degeneration of autonomic neurons show a characteristic inability to contract the distal urethral sphincter. Ultimately, the output neurons that fire will be those with the closest original firing regions to the input vector. The reasons for this smaller neuron size are unclear at present. We agree with barlow on the plausibility of rotation-tuned visual cortical neurons, which may be involved in the twisting motion experience in shepard's experiments. Parvocellular neurons limit motion acuity in human peripheral vision. This effect was observed in the presence or absence of primary sensory neurons.
