62. Clinical Case (2 of 2 questions): Noah is a 22yo patient undergoing physical therapy to recover from a severe patellar dislocation that he sustained during his recent soccer match. Following his injury, Noah has been placed in a knee immobilizer for 2 weeks, preventing knee flexion of his injured leg. In addition to weakness of the injured leg, Noah presents with significant difficulty in learning the new gait pattern required with wearing his knee immobilizer. A goal of your PT treatment is to improve the symmetry and control of Noah’s gait pattern by leveraging adaptive motor learning.   Noah is also experiencing muscle spasms and cramping, and is taking a drug that acts on GABAergic receptors for these symptoms. Which of the following synapses involved in adaptive motor learning will be MOST DIRECTLY affected by this drug?
