We examined the effect on unit activity with this spiking network with a distributed architecture consisting of up to four local networks connected by long range projections.
This major wave of growth and death establishes the long range projections between the deep grey matter and the cortex, and the short- and long- range cortico-cortical connections that are fundamental to integration of motor and cognitive functions [ 45].
This plasticity could thus be different to the form of plasticity expressed by the adult rats in the study by Diamond et al. The anatomical finding presented here suggests that the long range projections from these layer 2/3 neurons can be modified in isolation, implying that the mechanisms that result in the observed changes act relatively locally.
Increasingly, neuroscientists believe that the key to understanding how the brain works lies in its over-all neural circuitry, and the way that widely separated brain regions communicate through the long-range projection of nerve fibres.
Therefore, these cells were referred to as "long-range projection CR cells".
One of the most challenging aspects of spastin-related pathogenesis is that, despite its ubiquitous presence in many different organs, mutations of this protein result in the specific degeneration of processes of long-range projection neurons.
But Marilyn Moon, an economist and former Medicare trustee, said she had little confidence in such long-range projections.
Democrats today seized on the uncertainty of long-range projections to argue against the large tax cut President Bush is proposing.
That was the year when Goldman Sachs released the first of their long-range projections of the BRICs' economic fate over the next half century.
His staff's long-range projections envision threats not from Europe, where the Army is heavily positioned, but from Asia — possible conflicts in which Navy missiles and Air Force precision bombs would be the preferred assets.
Long-range projections by the Department of Education estimate that the default rate over 20 years, for borrowers who began repayment in 2009, is 17 percent; among students who attended profit-making colleges, the predicted default rate is 49 percent.
