Spectral output of subpopulations at Low Beta (LB) and High Beta (HB). All neural groups (in cortex and thalamus) have generated spectral responses within the beta band in both conditions as expected. Together with an increase in power a small increase in frequency peak of approximately 1–2 Hz is also apparent – when comparing the output generated in condition 1 (LB) with condition 2 (HB). Full curves represent the median spectral output across the 36 animals and shaded regions refer to the 25th and 75th percentiles.
