Question
Chapter 49, Problem 7TYK
Summary Introduction
Introduction: In the mammalian brain, long-term potentiation is the main form of synaptic plasticity. The strength of synaptic transmission is increased in long-term potentiation (LTP).

What evidence led Sherrington to conclude that transmission at a synapse is different from transmission along an axon? a. Chemicals that alter a synapse are different from those that affect action potentials. b. The velocity of a reflex is slower than the velocity of an action potential. c. Stains and microscopic observations demonstrate a gap at the synapse. d. Reflexes can go in either direction, whereas axons transmit in only one direction.
In some cases, people who suffer from depression can be prescribed a serotonin re-uptake inhibitor if they are determined to be resistant to behavioral treatment. Explain how a serotonin re-uptake inhibitor would alter concentrations of serotonin in the brain. Would this change occur at all synapses within the brain? Why or why not?
When do neural discharges in the brain have their strongest effect?
a. When the discharge rate of individual nerve cell is highest
b. When individual nerve cells fire in regular way
c. When the coherence of discharges in groups of nerve cells is greatest
d. When many nerve cells have burst activity

- What is a unique feature about the basal ganglia's anatomical organization? a. Few inhibitory circuits among many excitatory loops b. A balance of action-promoting and action-inhibition circuits c. Few excitatory circuits among many inhibitory loops d. Basal ganglia regions send motor output straight to the brain stem to control movements e. A balance of LTP and LTD circuitsarrow_forwardSuppose axon A enters a ganglion (cluster of neurons) and axon B leaves on the other side. Shortly after an experimenter stimulates A, an impulse travels down B. We want to know whether B is just an extension of axon A or whether A formed an excitatory synapse on some neuron in the ganglion, whose axon is axon B. How could an experimenter determine the answer? Try to think of more than one good method. Presume that the anatomy within the ganglion is so complex that you cannot simply observe the course of an axon through it.arrow_forwardGiven what you already know about the sensation of pain, what is the expected change in membrane potential when pain is felt by sensory receptors? Select one: a. The nerve impulses increase in strength and lower the threshold potential. b. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain. c. The nerve impulses occur more frequently and prevent neurons from entering the refractory period. d. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal.arrow_forward
