Functional brain areas associated with manipulation of a prehensile tool: a PET study.

30 Aug 2009 Using PET, brain areas representing the use of a well-learned tool (chopsticks) were investigated in 10 normal common users. The experimental task was to hold the tool in their right hand and use it to pick up and transport a small pin from a table. ... Read more...

Joint independent component analysis of structural and functional images reveals complex patterns of functional reorganisation in stroke aphasia.

9 Jun 2009 Previous functional activation studies in patients with aphasia have mostly relied on standard group comparisons of aphasic patients with healthy controls, which are biased towards regions showing the most consistent effects and disregard ... Read more...

A cerebral functional imaging study by positron emission tomography in healthy volunteers receiving true or sham acupuncture needling.

22 Jan 2009 Our recent studies have demonstrated that needling in Baihui, Shuigou and Shenmen enhances glucose metabolism in the frontal lobes, thalamus, temporal lobe, and the lentiform nucleus in vascular dementia. This study examined the effect of true, sham ... Read more...

Technical information about 'Nerve Net'

Definition: A meshlike structure composed of interconnecting nerve cells that are separated at the synaptic junction or joined to one another by cytoplasmic processes. In invertebrates, for example, the nerve net allows nerve impulses to spread over a wide area of the net because synapses can pass information in any direction.
