Breathlessness & the Brain | breathing, blood and brains
https://mariherigstad.wordpress.com/2016/10/17/breathlessness-the-brain
Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. Breathlessness and the Brain. October 17, 2016. So, which parts of the brain are involved in processing breathlessness? The first is the insular cortex. This anterior-posterior division may also be present in breathlessness, as the anterior insula appears to be more associated with the unpleasantness of breathlessness. The next on the list of likely suspects are somatosensory and motor regions. And in the cerebellum (a reg...

Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. Breathing on the brain. July 22, 2016. October 12, 2016. As easy as breathing? It may seem like it, but breathing is actually no easy process. It involves the precise integration of several systems, including, of course, the pulmonary and cardiovascular systems (gas exchange and transport, respectively). However, it also requires the direct involvement of the central nervous system: the brain. So to summarise, it is though...

How do eggs breathe? | breathing, blood and brains
https://mariherigstad.wordpress.com/2016/01/26/how-do-eggs-breathe
Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. How do eggs breathe? January 26, 2016. January 26, 2016. Bird’s eggs contain everything that the chick needs, except oxygen. So how exactly does the egg ‘breathe’? Pore area in total. Through these pores oxygen is taken in and carbon dioxide (CO. And loses 11 litres of water vapour. The rate of water loss depends on the porosity of the eggshell and the water vapour pressure gradient between the nest and egg. Out of the blo...

P-values for correlations in Excel | breathing, blood and brains
https://mariherigstad.wordpress.com/2016/07/05/p-values-for-correlations-in-excel
Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. P-values for correlations in Excel. July 5, 2016. October 12, 2016. This is just a quick post to describe how to calculate p-values for two-variable correlations in Excel. Annoyingly, there is no direct way of doing this. Excel will give you the correlation, but not its associated p-value. It can be done, however, in a slightly roundabout way. First, calculate the correlation between your groups:.

Predicting trouble: EEG, NO and stroke | breathing, blood and brains

Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. Predicting trouble: EEG, NO and stroke. August 31, 2016. October 12, 2016. We’ve recently published a paper titled “Electroencephalographic Response to Sodium Nitrite May Predict Delayed Cerebral Ischemia After Severe Subarachnoid Hemorrhage”. Which brings us to our question:. Patients who have the same clinical severity, no measurable genetic differences in nitric oxide production, and who seem exactly the same can go on ...

Breathlessness and opioids | breathing, blood and brains
https://mariherigstad.wordpress.com/2017/01/05/breathlessness-and-opioids
Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. January 5, 2017. January 16, 2017. We’ve recently published a paper on how opioids can modulate breathlessness. (The whole manuscript is open access here. Low-dose opioids can be used for treating chronic breathlessness, but we don’t know exactly how they work. In terms of breathing, opioids lower breathing by influencing brainstem respiratory centres. And are rich in opioid receptors. What did we do? What did we find?

Hemoglobin: a gamechanger | breathing, blood and brains

Breathing, blood and brains. A blog about physiology (mostly) #weareinternational. February 24, 2016. October 12, 2016. The supply of oxygen (O. Is crucial for life and there are two ways O. Can be carried in blood: dissolved or combined with hemoglobin. Can only supply a fraction of what the human body needs. One mL blood holds only about 0.003 mL O. At a partial pressure of oxygen (PO. Of 100 mmHg, and this can only be changed if we increase the PO. Not easily done) or the solubility of O. Atom has a f...
