I need help plesse Question 22Which statement about central pattern generators (CPGs) is false?Each half of a CPG excites the other halfEach half of a CPG excites muscles on the ipsilateral bodyCPGs are circuits of neurons that control rhythmic movementsCPGs can be modulated by descending inputsQuestion 23Descending inputs from the brain to the spinal cord are necessary for locomotion in lampreys and cats.TrueFalse

Central pattern generators (CPGs) are neural circuits that are capable of producing rhythmic motor patterns without continuous sensory input. They are found in many animals, from invertebrates to mammals, and are responsible for a wide variety of behaviors, including walking, swimming, breathing, and chewing.CPGs are located in the spinal cord and do not directly excite muscles. Instead, they send signals to motor neurons, which are the neurons that directly control muscles. Motor neurons are located on both the ipsilateral (same side) and contralateral (opposite side) of the body, so CPGs can control muscles on both sides of the body.Therefore, the correct option is b)Each half of a CPG excites muscles on the ipsilateral body.Answer 23: -a) TrueDescending inputs from the brain to the spinal cord are indeed necessary for locomotion in lampreys and cats. While spinal cord circuits can generate rhythmic patterns of activity, the initiation and modulation of locomotion in these animals often require descending signals from the brain.
