According to the theory of evolution, why might we call some parts of the brain the old brain and some parts the new brain? Old brain parts are what exist in very young children, and the new brain develops later The old brain developed first according to evolution The old brain becomes more active as we grow older The new brain deals with new information, while the old brain deals with information gathered when we were children The old brain is most affected by age deterioration (dementia) while the new brain remains unaffected :25 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

A spinal reflex differs from a normal sensory and motor reaction in that: A spinal reflex occurs only in response to extremely stressful stimuli In a spinal reflex, the spine moves the muscles in response as soon as the sensory information reaches the spine while usually the impulse must reach the brain before a response In a normal sensory/motor reaction, the spine transmits the information through afferent nerve fibers, while reflex reactions are transmitted along special efferent nerves Spinal reflexes are part of the central nervous system response, while normal sensory/motor reactions are part of the peripheral nervous system Spinal reflexes occur only in animals because humans are born without instinctual responses :25 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Which sentence most closely describes neural transmission? An electric charge is created in the neuron, the charge travels down the cell, and chemicals are released that cross the synapse to the next cell A chemical change occurs within the cell, the change causes an electric charge to be produced, and the charge jumps the gap between the nerve cells The electric charge produced chemically inside a group of neurons causes chemical changes in surrounding cells Neurotransmitters produced in the hindbrain are transmitted to the forebrain, causing electric changes in the cerebral cortex Neural transmission is an electrochemical process both inside and outside the cell :25 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
