Seeing me, you actually experience a disturbance in the sodium-potassium equilibrium across your neuron membranes. So all we have todo is send a few well-chosen molecules down into those cortical mitochondria, activate the right neurohumoral-synaptic transmission effector sites, and your fondest dreams come true.
