Which of the following neurotransmitters affects neurons involved in the increased heart rate and the slowing of intestinal activity during stress?

Some popular writers have been quick to assume that brain differences between men and women explain differences in behaviours in real life. For example, it has been concluded that brain differences explain why women would rather talk about feelings and men would rather talk about sports. Sex differences in the brain have been cited to explain men's resistance in asking for directions and women's willingness to ask for help when lost.

Transcranial magnetic stimulation uses a powerful magnetic field produced by a wire coil placed on a person's head in order to temporarily inactivate neural circuits.

Nerve impulses travel more slowly in babies than in older children and adults because:

The temporal lobes are at the top of the brain.

We know that both sides of the brain are involved in most activities but that some activities are more closely associated with one hemisphere or the other. List three activities that are most closely associated with the left hemisphere and three activities that are most closely associated with the right hemisphere.

The authors are careful to note that just because neurotransmitters are sometimes effective in treating disorders, that does not necessarily mean that abnormal neurotransmitter levels are causing the disorder. Explain why this is true.

Which structure is involved in drives associated with survival of both the individual and the species?

In the peripheral nervous system, ________ carry messages from special receptors in the skin, muscles, and other internal and external sense organs to the spinal cord, which sends them along to the brain.
