Drinking once can change the brain permanently

The German research team wrote in the latest issue of the National Academy of Sciences that the research carried out by the genetic model system of the black -bellied fruit flies showed that even drinking can permanently change the form of the brain neurons permanently, and and the form of the brain neurons permanently, and the form of the neurons of the brain, and the form of the neurons, and the form of the neurons, and the form of the neurons, and the form of the neurons, and the form of the neurons, and the form, The structure of the "traffic fortress" in the brain and the dynamics of mitochondria to provide energy for cells will also be affected by alcohol.

The team verified its assumptions through the research of fruit flies and mouse models, and found that ethanol -induced changes in the balance between mitochondrial dynamics and neuronal synapses. Mitochondria provide energy for cells, especially nerve cells. Mitigation can move to better transport energy to cells. Studies have found that the mitochondrial movement used in ethanol treatment is disturbed; chemical balance between certain synapses is also disturbed. These changes are permanent, and the changes in animal behavior also confirmed this: In the future life, the alcohol intake of mice and fruit flies increased.

Researchers explained that the formal reshaping of neurons is the basis for learning and memory. These so -called cell plasticity mechanisms are the core of learning and memory, and they are also considered the core of drug -related reward memories. Therefore, some morphological changes observed by scientists may affect the formation of memory -related memory. In addition, the migration of neuron mitochondria is also important for synapses and plasticity. Researchers have speculated that these ethanol dependence on cell changes is essential for the development of addiction.
