Question

As part of your biological psychology class, you conduct an experiment in which a rat's brain is continuously infused with a hormone called ghrelin. Based on what you've learned about ghrelin in your psychology text, you predict that the rat will:

Answer 1

Continuous infusion of ghrelin in a rat's brain is predicted to increase hunger and food-seeking behavior due to the hormone's stimulating effect. Ghrelin acts on the hypothalamus region of the brain, which regulates hunger and satiety signals.

Step-by-step explanation:

Ghrelin is a hormone that stimulates hunger and increases appetite. By continuously infusing a rat's brain with ghrelin, you can predict that the rat will likely experience increased hunger and food-seeking behavior. Ghrelin acts on the hypothalamus region of the brain, which is responsible for regulating hunger and satiety signals. The continuous infusion of ghrelin may overpower the satiety signals, leading to increased hunger and a drive to eat.
