  • Values shown are means ± SE. Asterisks (

  • * ) indicate values significantly different from regular spiking (RS) cells (t-test, P < 0.01). Pluses (+) indicate values significantly different from fast-spiking (FS) cells (t-test, P < 0.01). Baseline voltage is measured after applying a holding current. LTS, low-threshold spiking.
