- Nociception to the brain www.bodyinmind.com.au © lorimer moseley 2010 thalamus “Danger in my area”
- Nociception to the brain www.bodyinmind.com.au © lorimer moseley 2010 - Relay/prio ritisation centre ant thalamus “what i s the most import know thin g for the brain to ” about right now? Site of the famous pain gate
- Nociception to the brain www.bodyinmind.com.au © lorimer moseley 2010 thalamus There are actually 3 different types of these...
- Nociception to the brain www.bodyinmind.com.au © lorimer moseley 2010 thalamus Periaqueductal Gray There are about 600 descending neurons for every spinal nociceptor. 600 1
- Nociception to the brain www.bodyinmind.com.au © lorimer Projections to PAG come from moseley 2010 all over the brain thalamus Periaqueductal Gray
- Nociception to the brain All happens without us knowing about it thalamus Can activate protective responses without us knowing about it Nociception is happening now Right now. www.bodyinmind.com.au © lorimer moseley 2010
- Acute pain basics www.bodyinmind.com.au © lorimer moseley 2010
- Pain emerges from the brain with activity in a particular and peculiar network of brain areas Individually specific Every brain cell involved also does other things Hoffman et al (2004) NeuroReport Text Obliteration of one ‘node’ does not remove pain - the brain works out how to produce pain Professor Wiki Pedia (2010) using other brain cells. MacIver et al (2008) Brain www.bodyinmind.com.au © lorimer moseley 2010
- How does the brain produce a conscious protective response? www.bodyinmind.com.au © lorimer moseley 2010
