But brain researchers have discovered that when we consciously develop new habits, we create parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks.
This concentration gradient is extremely important for setting the resting membrane potential of excitable cell membranes, which is needed for normal contraction of smooth, cardiac, and skeletal muscle.
When your brain cells multiply, your memory can improve, viewed from a biological perspective, this makes sense because animals that are better at remembering dangerous situations can avoid them in the future.
