Respiration patterns of resting wasps (Vespula sp.)
We investigated the respiration patterns of wasps (Vespula sp.) in their viable temperature range (2.9-42.4°C) by measuring CO2 production and locomotor and endothermic activity. Wasps showed cycles of an interburst-burst type at low ambient temperatures (Ta<5°C) or typical discontinuous gas exchange patterns with closed, flutter and open phases. At high Ta of >31°C, CO2 emission became cyclic....
متن کاملLow-frequency respiration related signals in resting state fMRI: a comparison of end-tidal CO2 and respiration volume per time
Introduction Functional connectivity analysis has been used to map several consistent resting state networks by exploiting coherent low-frequency fluctuations in the BOLD signal. The assumption in most of the fMRI literature is that these correlated fluctuations are neuronal in origin. Others sources of low-frequency fluctuations exist in fMRI data that are unrelated to neuronal activity. These...
متن کاملEstimation of the resting reflex hypoxic drive to respiration in patients with diffuse pulmonary infiltration.
1. Oxygen breath tests were performed in nine patients with diffuse pulmonary infiltration whose resting arterial PO2 (Pa, O2) ranged from 8-9 kPa to 11-8 kPa. The inspired air was suddenly replaced with oxygen for 30 s and the percentage fall in ventilation over the last 10 s was measured. 2. Pa,O2 rose rapidly and exceeded 16 kPa within 20 s in each patient. 3. The ventilation fell significan...
متن کاملMorphine inhibits resting respiration, but it attenuates reflexive respiratory suppression in anesthetized cat through kappa-receptor.
Noxious stimulation of thin-fiber muscular afferents induces a reflexive respiratory suppression that we call "poststimulus respiratory suppression." In anesthetized, vagotomized, paralyzed, and artificially ventilated cats, morphine depressed the level of resting respiration (inhibitory effect on resting respiration) and attenuated the magnitude of the poststimulus respiratory suppression (exc...
متن کاملLong-term mindfulness training is associated with reliable differences in resting respiration rate
Respiration rate is known to correlate with aspects of psychological well-being, and attention to respiration is a central component of mindfulness meditation training. Both traditional contemplative systems and recent empirical evidence support an association between formal mindfulness practice and decreased respiration rate. However, the question of whether long-term mindfulness training is a...
