Question

A neuron that uses the neurotransmitter glutamate is on the left side of the worm, and activity of this neuron causes the worm to turn to the left. However, the synapse for this neuron also can produce anandamide, which when produced lessons the amount of glutamate used in signaling. A neuron that uses the neurotransmitter serotonin acting on a 5HT2A receptor is on the right side of the worm, and activity of this neuron causes the worm to turn to the right. When both synapses are equally active, the worm moves straight ahead, and velocity is proportional to the amount of neuron activity. When the synapse on one side is more active than the one on the other side, then the worm turns to the side with the most neuronal activity. 1. Which way does the worm turn after taking LSD? a. turns to the left b. turns to the right c. continues straight ahead 2. Which way does the worm turn after taking phencyclidine (PCP)?. a. turns to the left b. turns to the right c. continues straight ahead 3. Which way does the worm turn after taking mescaline or peyote? a. turns to the left b. turns to the right c. continues straight ahead 4. Which way does the worm turn after taking salvinorin A? a. turns to the left b. turns to the right c. continues straight ahead

Explanation / Answer

a)1 because lsd is a serotonin agonist b)2 because phencyclidine is a glutamate agonist
