Question

The connectivity of the human brain–and the development of this connectivity–can be described at coarse, intermediate, and fine levels. At the coarsest level, brain areas are created by the process of [ Select ] , which occurs [ Select ] . At the intermediate level, connections between individual neurons are created by the process of [ Select ] . The number of synapses peaks [ Select ] and then declines as a result of a process called [ Select ] . At the finest level, the strengths of individual neurons are adjusted as a result of experience. This is the primary mechanism of plasticity [ Select ] .

5) synaptic pruning, during embryonic development
6) synaptic pruning, during adulthood
7) neuroplasticity
8) neurogenesis

Answer 1

The connectivity of the human brain can be described at different levels. At the coarsest level, brain areas are created through neurogenesis during embryonic development. At the finest level, neural plasticity occurs as a result of experience.

Step-by-step explanation:

The connectivity of the human brain at different levels can be described. At the coarsest level, brain areas are created through the process of neurogenesis during embryonic development. At the intermediate level, connections between individual neurons are created through the process of synaptogenesis.

The number of synapses peaks during embryonic development and then declines as a result of a process called synaptic pruning. At the finest level, the strengths of individual neurons are adjusted as a result of experience, which is the primary mechanism of neuroplasticity.
