Neurons, like all cells, maintain different concentrations of certain ions (charged atoms) across their cell membranes. Imagine the case of a boat with a small leak below the water line. In order to keep the boat afloat, the small amount of water entering through the leak has to be pumped out, which maintains a lower water level relative to the open sea. Neurons do the same thing, but they pump out positively charged sodium ions. In addition, they pump in positively charged potassium ions (potash to the gardeners out there!!) Thus there is a high concentration of sodium ions present outside the neuron, and a high concentration of potassium ions inside.
Virat Kohli - first to 4000 runs in IPL. 4002 Runs for Virat Kohli in his IPL career. In his innings of 113 against Kings XI Punjab, he became the first batsman to complete 4000 runs in the IPL, going past Suresh Raina's tally of 3985. Before the start of the season, Kohli was fourth on the list.
Still, thatâs no excuse for William Holbert. In 2,335 at-bats over the course of 13 seasons, Holbert didnât manage to hit a single home run. By contrast, in the first 2,335 at-bats of his career, Albert Pujols had already hit over 150 home runs.
