Question

What does the term "half-center" structure refer to in the context of neural systems?

A) A structure in the brain responsible for sensory processing.

B) A network of neurons that generates rhythmic patterns.

C) The midbrain region that coordinates voluntary movements.

D) The area of the brain associated with higher cognitive functions.

Answer 1

A 'half-center' structure in neural systems refers to a network of neurons responsible for generating rhythmic movement patterns through alternating excitation and inhibition.

Step-by-step explanation:

The term “half-center” structure refers to a network of neurons that generates rhythmic patterns. It is often used in the context of neural systems that control repetitive movements such as walking or breathing. These half-centers are comprised of two groups of neurons that rhythmically inhibit each other, leading to an alternating excitation and inhibition of motor neurons. The activity in these networks is responsible for the coordination and timing of rhythmic motor patterns.
