Nearly every chemical and cell that helps run and control the brain can be found in the gut. Until relatively recently people thought that the gut’s muscles and nerves were controlled by the brain through a pathway, that simply increased or decreased rates of activity. That was until someone decided to count the brain cells in the gut. Surprisingly they found that it contained over a hundred million nerves. That's more than the spinal cord has. And the nerve that connects the brain to the gut has only a couple of thousand nerve cells. The gut also seems to follow similar sleep patterns with 90-minute periods of inactivity followed by short periods of rapid muscle movement.

Option 1: "a complex spinal cord"

Explanation: This option is incorrect because the text discusses the gut's nerve cells and their comparison to the spinal cord, but it does not suggest that the gut is a 'complex spinal cord.' Instead, it emphasizes the gut's own nerve system, which is distinct from the spinal cord.

Option 2: "an inactive mind"

Explanation: This option is incorrect as the text does not imply that the gut is associated with an 'inactive mind.' In fact, it highlights the active role of the gut's nerve cells, which contradicts the idea of inactivity.

Option 4: "a sensitive stomach"

Explanation: This option is incorrect as it oversimplifies the role of the gut. The text discusses the gut's nerve cells and their functions, which go beyond just being 'sensitive.' It does not support the notion that the gut is merely a sensitive stomach.
