question 132

Multiple Choice

Modern research on the physiological mechanisms responsible for hunger have revealed that

• A)as a function of hunger regulation, the lateral hypothalamus (LH) is the "hunger on" centre and the ventromedial hypothalamus (VMH) is the "hunger off" centre
• B)while involved in hunger regulation, the lateral hypothalamus (LH) and ventromedial hypothalamus (VMH) are not actually "hunger on" and "hunger off" centres
• C)as a function of hunger regulation, the ventromedial hypothalamus (VMH) is the location of both the "hunger on" and "hunger off" centres
• D)as a function of hunger regulation, the lateral hypothalamus (LH) is the location of both the "hunger on" and "hunger off" centres

Definitions:

Movement

The act or process of moving, involving physical change in position or relocation of an object or organism.

Back Propagation

A key algorithm in neural networks used for training, by adjusting weights based on the error rate obtained in the previous epoch.

Neuroplasticity

The brain's ability to reorganize itself by forming new neural connections throughout life, allowing the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or changes in their environment.

Absolutely Refractory

The state of an axon in the repolarizing period, during which a new action potential cannot be elicited (with some exceptions) because gate 2 of sodium channels, which are not voltage-activated, are closed.
