Though speculative, alteration in brain function may offer some interesting perspectives and insights into these issues.
While it has often been suggested that developmental changes in brain function may reflect and contribute to changes in brain structure (Cohen Kadosh 2011; Crone and Ridderinkhof 2011; Scherf et al. 2012), no studies have directly investigated this with regard to face-processing abilities.
But the importance of sleep to our brain function may be even more fundamental.
That is, some activation in functional brain imaging studies may reflect brain activity that is not essential for the function of interest.
Hence, preceding activation in one brain area compared to a second brain area may reflect true causal influence or, alternatively, a hemodynamic response function that peaks earlier in time compared to the second area [ 11].
Other ornithomimosaurs have proportionally large brains, and the small brain of Deinocheirus may reflect its social behaviour or diet.
Overall, these overlapping brain changes may reflect the central sensitization mechanism underlying FM [56].
The present study thus hypothesized that TTH and migraine are different in brain morphology, which may reflect their distinct symptomatology, sensory processing, and disease burden.
This observation of multiple dynamic aspects of FC of a single region, the PCC in this case, may also characterize brain function more generally and reflect a fundamental aspect of functional organization in the brain.
It is reported that most patients with depression may have alterations in their thyroid function including slight elevation of the serum FT4, blunted TSH response to thyrotropin-releasing hormone (TRH) stimulation[ 60], and loss of the nocturnal TSH rise and this may reflect brain hypothyroidism in the context of systemic euthyroidism[ 61].
The adrenal cortex secretes cortisol and aldosterone, and their concentrations may reflect adrenocortical function.
