Researchers have explored temporal cortical activations by utilizing magnetoencephalography (MEG). Like Koodo, it only works on postpaid activations, known as Pay After. Studies have revealed the differences in neural activations of inner dialogues versus those of monologues. These dopaminergic activations of the mesolimbic pathway are accompanied by the perception of reward. Sales and new activations resumed on November 16, 2009. "left" activations on the beta node each time it stores a new WME list. A microcontroller can be used to enable precise timing of phase activations. Supervisor-given target activations can be supplied for some output units at certain time steps. On October 20, 2011, AT&T surpassed one million activations. These events including turns, changes in altitude, sensor activations/de-activations and landing. In principle this is similar to Scheduler Activations. These changes are referred to as "activations". The brigade saw five brief activations for service over a 40-year span. Other activations have included a private luncheon honoring former President Bill Clinton.
