3a - The individual hypothalamic concentrations of neurotensin over the 13 months that data were collected. A three cosinor function was fit to the data as both cosinor and spectral analysis indicated a statistically significant fit for this number of peaks. (From reference 13 with permission.)
3b - The individual hypothalamic concentrations of neuromedin N (NMN) over the 13 months of data collection. Data were fit to a two cosinor function in this case, although both spectral and cosinor analysis indicated that both a three and this two cosinor function were statistically significant for these data.
