Answer:

The correct option is a. "increased cortical mass, increased numbers of neurons, increased synaptic connections, increased neurotransmitter amounts, and increased myelination. "

Explanation:

Rodents that have been raised in enriched environments were found to have thicker cerebral cortex containing approximately 25% more synapses in a study conducted by Mark Richard Rosenzweig. This increase in <em>synapses</em> implies in an increase in <em>neurons</em> and <em>neurotransmitters</em>, which also indicates an increase in <em>myelination</em>.

During the action potential of a neuron, which ion is primarily crossing the membrane during the depolarization phase, and in wh
iragen [17]
The answer is Na + is entering the cell and the K + is leaving, during the depolarization phase of the action potential open Na + channels allow Na + ions to diffuse into the cell. This inward movement of positive charge makes the membrane potential more positive. The depolarization phase is a positive response sequence where open Na + channels cause depolarization which in re-occurrence causes more voltage gated Na+ channels to open.
