True false questions

Neuron cell bodies are only found in CNS but not in PNS, while axons are the opposite. True False

If the threshold for AP is set at -60mV, a neuron receives total 8 EPSPs of -65mV and 6 IPSPs of -75mV, after the summation, this neuron will launch an AP.  True  False

Sodium-potassium exchange pump is the key factor in maintaining the concentration gradients of the cations across the plasma membrane. True  False

The resting potential, -70mV, being close to K+ equilibrium potential, -90mV, is because neuron is much leakier to K+ than to Na+. True False

Axon hillock is where the threshold potential is set to launch an action potential. True False

K+ leak channel is responsible for both hyperpolarization and repolarization in the action potential. True False

True or False Questions: Determine if true or false. If false why? 1) Premature efforts to treat problem behavior before determining its function can be inefficient, ineffective, and even harmful. 2) Research has found that functional analyses conducted in natural environments (e.g., classroom settings) often yield the same (or even clearer) results compared to those conducted in simulated settings. 3) Problem behavior can only be maintained by one function. Behaviors are not multi-functional. 4) Indirect functional assessment procedures are referred...
