A research on animals suggest that intake of excessive alcohol reduces the number of neurons in the hippocampus which is responsible for storage of memory and softens mitochondria, the producer of energy in cell, their impairment can damage brain cells. Another study conducted on two new animals shows, aerobics amend some of the effects of excessive drinking on the brain. The above mentioned studies were presented earlier this month at Annual Sin tha pa society for Neuroscience meeting held in San Diego. The study based on damage of brain cells due to excessive drink was conducted by physiologist at the University of Louisville on adult male mice. For 12 weeks, the adult male mice received either alcohol inserted through injection or salt water. Half the animals in each group were put through intense treadmill workouts everyday. The second study was conducted by researchers from United of Houston which focused on binge drinking , one night for 11 weeks , tubes were inserted into the stomachs of female rats to provide steady doses of alcohol nor non-alcoholic liquid. Half of the rats ran on wheel for upto two hours every three days a week. In both the studies , the brain of the rats that received exercise after alcohol were significantly different from those of their sedentary peer. Mitochondria of inactive mice had weekend neurons whereas the runners had harder mitochondria.
