Presynaptic excitation - Study guides, Class notes & Summaries

presynaptic inhibition to gate the monosynaptic Ia input to motor neurons, and it is modulated according to the needs of the task (T/F) presynaptic inhibition is affected by spinal cord lesions (SCI, ALS, MS) True Conditioning stimulus (e.g., brief tendon vibration of tibialis anterior) depresses H-reflex in soleus (and quads heteronymous muscle to soleus) Heteronymous soleus and quads are heteronymous with each other; the tibialis is the antagonist with the soleus. ...

1. Volume neurotransmission refersto? The diffusion of neurotransmitter to nearby neurons. 2. Retrograde neurotransmissionsrefersto? The flow of neurotransmitter from postsynaptic neuron to presynaptic neuron 3. Use the following CYP450 table to hypothesize drug interactions and their clinical significance for a patient on clozapine who carbamazepine, a mood stabilizer?
