Neuroplasticity, i.e., the modifiability of the brain, is different in development and adulthood. The first includes changes in: (i)neurogenesisand control of neuron number; (ii)neuronal migration; (iii) differentiation of the somato-dendritic and axonal phenotypes; (iv) formation of connections;...
In the 1920s, researcher Karl Lashley found evidence of changes in neural pathways of rhesus monkeys. By the 1960s, researchers began to explore cases in which older adults who had suffered massive strokes were able to regain functioning, demonstrating that the brain was more malleable than previ...

in many forms and for many reasons and at any time during our lifetime. For example, children acquire new knowledge in vast quantities and their brain changes significantly at these times of intensive new learning. New learning may also be required in the presence of neurological damage caused,...
A two-year old rat, R222, survived a life-time of extreme hydrocephaly affecting the size and organization of its brain. Much of the cortex was severely thinned and replaced by cerebrospinal fluid, yet R222 had normal motor function, could hear, see, sme

children, younger adults, and older adults. Whereas the use of a spatial strategy (using the relative positions of landmarks for way finding, known to activate the hippocampus) was more prevalent in children and younger adults, the use of a response strategy (memorizing a series of left and...
