2007 American Journal of Physiology. Regulatory Integrative and Comparative Physiology  
The relative contribution of central commands to the control of heart period, estimated from the negative peak value of the CCF, was lower in SHR than in WKY during REMS.  ...  The relative baroreflex contribution to the control of heart period, estimated from the positive peak value of the CCF, was lower in SHR than in WKY during QW but not during NREMS.  ...  Our CCF analysis, which is based on the whole time series of HP and MAP, yields information similar to other linear techniques, which focus on spontaneous ramps of arterial pressure and are based on the  ...

Alessandro Silvani, Valentina Asti, Tijana Bojic, Vera Ferrari, Carlo Franzini, Pierluigi Lenzi, Daniel A Grant, Adrian M Walker, Giovanna Zoccoli
2005 Pediatric Research  
Heart rhythm thus may be more tightly controlled by the baroreceptor reflex and less dependent on central autonomic commands in quiet sleep than either in quiet wakefulness or in active sleep.  ...  HP and MAP beat-to-beat values were computed from 120-s blood pressure recordings during quiet wakefulness, active sleep, and quiet sleep.  ...  Time lags at the positive peak of the HP versus MAP cross-correlation function may reflect the latency of the maximal sinus node response to a change in MAP (26) rather than the latency of the earliest  ...

Recovery of Neurological Function Despite Immediate Sleep Disruption Following Diffuse Brain Injury in the Mouse: Clinical Relevance to Medically Untreated Concussion

Rachel K. Rowe, Jordan L. Harrison, Bruce F. O'Hara, Jonathan Lifshitz
2014 Sleep  
In the hour following the first dark onset, sleep-disrupted mice exhibited a significant increase in sleep; however, this increase was not sustained and there was no rebound of lost sleep.  ...  Regardless of sleep disruption, mice showed a time-dependent improvement in Rotarod performance, with braininjured mice having significantly shorter latencies on day 7 compared to sham.  ...  Kathryn Saatman for training on behavioral techniques used in these studies. We would also like to thank the members of the laboratory for their help with sleep disruption.  ...

Influence of resistance exercise on autonomic nervous system and sleep
Uticaj vežbanja uz primenu otpora na autonomni nervni sistem i spavanje

Ivan Stanić, Tomislav Smoljo, Barbara Barun, Mario Habek
2018 Medicinski Podmladak  
There are other factors responsible for the influence of exercise on our body.  ...  In this article we will discuss multiple benefits of resistance training on autonomic nervous system function and sleep.  ...  Autoregulation in skeletal muscles during increased needs causes vasodilatation and therefore decreased amount of blood would be directed to the CNS if there were not any other regulatory mechanisms.  ...
