respond to a stimulus and are basic for survival. For example‚ the rooting reflex is when the baby turns its head toward the direction of a stimulus to the cheek. This reflex facilitates the sucking reflex in order for the newborn to receive nutrients. Another sensory stimulation is bright lights which will cause the eye-blink reflex. Most of the reflexes are important to test for neural function because the absence of a reflex could indicate brain damage‚ immaturity‚ or slow responsiveness. Another

CS306- INTELLIGENT SYSTEMS Part – A 1. There are well-known classes of problems that are intractably difficult for computers‚ and other classes that are provably undecidable. Does this mean AI is impossible? (2) No‚ it means that AI systems should avoid trying to solve intractable problems. Usually this means they can only approximate optimal behavior. Notice that even humans do not solve NP- complete problems. Sometimes they are good at solving specific instances with a lot of structure

useful type of PNF is the CRAC (contract-relax‚ antagonist-contract) technique‚ which uses isometric muscle contractions as its basis. PNF stretching is best performed with a partner. Muscle recruitment is enhanced through the use of the appropriate reflex and proprioceptive stimuli. The efficient recruitment of motor patterns involves the use of the following PNF

1. Compare the reaction times for voluntary vs. involuntary activation of the quadriceps muscle. What might account for the observed differences in reaction times? Outline what has to occur in the body for each reaction to occur. Refer to your drawing from Step 24. Information from the flow chart you created in Activity 2.2.1 might also be helpful. The involuntary activation of the quadriceps muscle was faster than voluntary time; the reason could be that when you had to hear the sound for
