Just a brief round-up today.
An fMRI study provided evidence of different regions involved in learning new verbs (left posterior temporal gyrus and left inferior frontal gyrus) and nouns (left fusiform gyrus) as well as a relationship between hippocampal activity and the efficiency of learning new nouns. This information could be of relevance to a number of conditions which involve disorders of language and memory. For more information on the study see here.
A study involving neural prosthetic devices in people provided evidence of the function of the beta and delta oscillations identified in the EEG. Based on their findings about the timing of the oscillations, the researchers concluded that the beta oscillations were strongly associated with anticipating commands for initiating movements. For more information see here.
Discover reports on some experimental evidence to suggest that smells and sounds are perceived together as hybrid ‘smounds’ – at least in a murine model. These conclusions are based on the activity of cells in the olfactory tubercle which respond not only to smells but also auditory tones presented alone or in combination with smells*.
Vaughan Bell has a good round-up of Spike Activity where he looks at the recent findings on the XMR virus in Chronic Fatigue Syndrome amongst other studies.
Brain-Derived Neurotrophic Factor has been suggested as a possible therapeutic intervention in dementia. The authors of a new study reported on here found that slow versus rapid application of BDNF to cell cultures had different effects and this is discussed further in the report.
* Since smells are closely related to taste it is tempting to speculate that this could even be relevant to Pavlovian conditioning if confirmed in other species.
