Final answer:
The effect of aging on the nervous system that is NOT true is the increase in synaptic connections, as aging typically leads to a decrease in these connections.
Step-by-step explanation:
The question asks which of the following is NOT an effect of aging on the nervous system:
- a) increase in synaptic connections
- b) decrease in blood flow to the brain
- c) reduction of brain size and weight
- d) decrease in neurotransmitter production
The correct answer is a) increase in synaptic connections. As we age, the nervous system typically experiences a decrease in synaptic connections rather than an increase. Other changes that commonly occur with aging include a decrease in blood flow to the brain, a reduction of brain size and weight, and a decrease in neurotransmitter production. The increase in synaptic connections is generally associated with neural plasticity and learning during younger stages of life, rather than with aging.
