You've watched the videos above and read the rest of the Rappers and Zombies page by now. To begin to try to explain the behavior of zombies, let's think about the role of the hypothalamus in regulating the release of hormones. Here's the recap from the video on the Human Endocrine system above: 1. the hypothalamus releases a hormone that tells the 2. pituitary gland to 3. release another hormone into the bloodstream. This 4. hormone travels the bloodstream and 5. links with hormone receptor molecules in particular glands/muscles/tissues. When a particular hormone reaches a certain level in the bloodstream, the hypothalamus either continues to produce or ceases to produce that hormone. Now, let's think about some of the hormones that are involved in hunger and appetite. Leptin is a hormone that suppresses the appetite. The higher the leptin levels, the lower the food intake. Ghrelin is a hormone that increases the appetite. It increases before meals and essentially tells the stomach to tell us that we're hungry.

The brain scan in the Walking Dead scene shows that there is just enough electrical activity to stimulate the hypothalamus. Additionally, the activity from the brain scan also shows stimulation in the limbic system, which houses the amygdala. Finally, note that the activity does not travel very far through the cerebral cortex, particularly the frontal lobes, where judgment occurs. Given what you know about hormones, the limbic system, amygdala, and frontal lobes, explain the zombies' hunger, aggression, and lack of inhibition. Be sure to incorporate content from the module and/or the chapter text into your work.

The behavior of zombies, including their insatiable hunger, heightened aggression, and diminished inhibitory control, can be comprehensively understood through the lens of neuroendocrinology and neuroanatomy. Drawing on insights from the human endocrine system and brain function, particularly the hypothalamus, limbic system, amygdala, and cerebral cortex, provides a plausible explanation for these atypical behaviors.

Central to this understanding is the hypothalamus, a small but vital brain structure responsible for regulating essential physiological processes through hormone release. It acts as the master regulator, orchestrating the hypothalamic-pituitary axis to maintain homeostasis. When stimulated, the hypothalamus releases hormones that influence various glands and tissues, including those involved in hunger and aggression.

In the context of zombie behavior, brain imaging data suggest that the hypothalamus receives just enough electrical stimulation to activate its functions without the higher-order processing of the cerebral cortex. The limbic system, particularly the amygdala, shows activation in the scan, indicating heightened emotional responses. The amygdala is crucial for processing fear, aggression, and primal drives, and its activation could explain the zombies' aggressive nature.

The involvement of hormones such as ghrelin and leptin further elucidates the hunger component. Ghrelin, known as the "hunger hormone," rises before meal times to signal hunger, whereas leptin suppresses appetite when energy stores are sufficient. In zombies, the hypothalamic circuits controlling these hormones are likely dysregulated or hyperactivated, leading to persistent hunger signals regardless of actual energy needs. This persistent craving for flesh aligns with elevated ghrelin activity and reduced leptin signaling.

Moreover, the lack of inhibition observed in zombies can be attributed to diminished activity in the frontal lobes—the regions responsible for judgment, impulse control, and decision-making. The minimal cortical activity implies that higher-order processes are compromised or suppressed, leaving primal instincts unchecked. This neurofunctional pattern results in zombies acting on instinctual drives—hunger and aggression—without the moderating influence of logical thought or moral reasoning.

The convergence of these neural and hormonal factors creates a state of heightened primal drives, characterized by relentless hunger and violent tendencies, with diminished capacity for self-control or social restraint. This aligns with the observed behavior in zombie scenarios and offers a scientific basis for understanding their actions. Essentially, the abnormal activation of the hypothalamic and limbic regions, coupled with suppressed cortical functions, produces a creature driven solely by instinctual, survival-related impulses rather than rational thought.
