... Because of its noninvasive nature and good spatial resolution, functional magnetic resonance imaging (fMRI) has been increasingly used in studying human brain function since its emergence in 1992 (Bandettini et al. 1992; Kwong et al. 1992; Ogawa et al. 1992). In the field of human motor control, rec ...

For example, between a certain brain activity and the behavioral act many events occur: Synaptic transmission, the gradual build-up of post-synaptic potentials, action potentials, and so on. These events take time, resulting in a delay between the brain activity and the behavioral act th ...

In Section 4 I will bring the distinction between stimulation-connection and simulationreplacement methodology to bear on some claims recently made by Craver (2010) and Chirimuuta (2013) on the epistemic value of bionic systems. In particular, based on that distinction, I will show that Craver’s (20 ...

Aging brain

Age is a major risk factor for most common neurodegenerative diseases, including Mild cognitive impairment, Alzheimer's disease, cerebrovascular disease, Parkinson's disease and Lou Gehrig's disease. While much research has focused on diseases of aging, there are few informative studies on the molecular biology of the aging brain (usually spelled ageing brain in British English) in the absence of neurodegenerative disease or the neuropsychological profile of healthy older adults. However, research does suggest that the aging process is associated with several structural, chemical, and functional changes in the brain as well as a host of neurocognitive changes. Recent reports in model organisms suggest that as organisms age, there are distinct changes in the expression of genes at the single neuron level. This page is devoted to reviewing the changes associated with healthy aging.
