Molly is likely higher at risk for. With increasing flow rates, both the maximum height of the Cu dendrite, Hmax, and the growth rate of the Cu dendrite, Ravg, decreased, confirming that cross-flow suppressed dendrite growth in the overlimiting regime ( Fig. Nat Neurosci 4:359365, Niell CM, Meyer MP, Smith SJ (2004) In vivo imaging of synapse formation on a growing dendritic arbor. 2c). They suggested neurogenesis is rare in adults or that it happens to such a small degree that its undetectable. The traditional approach emphasizes extensive change from birth to adolescence, little or no change in adulthood, and decline in late old age. Some of the studies point to age being less of a factor in cessation of neurological development, with environment (e.g .
