Figure 6.
The numbers of AVP-immunoreactive and VIP-immunoreactive neurons in the suprachiasmatic nucleus are not associated with sleep fragmentation as assessed by actigraphy. (A) VIP-immunoreactive suprachiasmatic nucleus neuron counts (n = 22). (B) AVP-immunoreactive suprachiasmatic nucleus neuron counts (n = 22). All panels show partial regression plots of models adjusted for age, sex, and presence/absence of Alzheimer's disease. r indicates the partial correlation coefficient between the number of neurons and sleep fragmentation measured using kRA). SCN = suprachiasmatic nucleus.
