What does NS stand for in classical conditioning?
Neutral Stimulus. In classical conditioning, a neutral stimulus (NS) is a stimulus that nitially does not evoke a response until it is paired with the unconditioned stimulus.
What is the difference between conditioned and unconditioned reflex?
These examples, and other reflexes typically present in normal animals or humans, are called “ unconditioned reflexes (URs).” The stimulus that elicits a UR is called the “unconditioned stimulus (US).” In contrast, a “ conditioned reflex (CR)” is a reflex that has been created or modified through a particular training.
Is knee jerk is a conditioned reflex?
A reflex is built into the nervous system and does not need the intervention of conscious thought to take effect. The knee jerk is an example of the simplest type of reflex. When the knee is tapped, the nerve that receives this stimulus sends an impulse to the spinal cord, where it is relayed to a motor nerve.
Is knee jerk reflex unconditioned?
Knee-jerk reflex and motor-neuron connection. Encyclopædia Britannica, Inc. Many automatic, unconditioned reflexes can thus be modified by or adapted to new stimuli, making possible the conditioning of reflex responses.
What is a unconditioned reflex?
: a reflex that is inborn or dependent on physiological maturation rather than on learning.
What does exaggerated knee reflex indicate?
Spasticity is stiff or rigid muscles. It may also be called unusual tightness or increased muscle tone. Reflexes (for example, a knee-jerk reflex) are stronger or exaggerated. The condition can interfere with walking, movement, speech, and many other activities of daily living.

Although the knee jerk reflex is mediated by the L3 and L4 nerve roots, evidence exists that altered knee jerk expression may occur with exclusively L5 radiculopathy.
How does the knee jerk reflex protect the body?
This is a reflex of proprioception which helps maintain posture and balance, allowing to keep one’s balance with little effort or conscious thought. The patellar reflex is a clinical and classic example of the monosynaptic reflex arc.

Who has the fastest reflexes in the world?
Recently, fast reflex responses of skipper but- terflies (Hesperiidae) to the photographic flash were reported and were found to be among the fastest ever recorded (<17 ms)—comparable to the fastest reflexes of the vertebrates (Sourakov 2009).
