 LTP may last A) hours in living animals and indefinitely in a brain slice. B) hours in a brain slice and indefinitely in living animals. C) a few seconds in living animals and several hours in a brain slice. D) a few seconds in a brain slice and several hours in living animals.

 LTP is similar to long-term memory in which of the following ways? A) It requires input to be presented at rates of 2 per second or less. B) It occurs only in the hippocampus. C) It takes only seconds to develop and lasts indefinitely. D) It requires the activity of neurons that release ACh.

 "Associativity" in the Hebbian synapse refers to the A) use of the same type of neurotransmitter in both the pre- and postsynaptic neurons. B) simultaneous activity of several synapses on the same postsynaptic neuron. C) nearly simultaneous activity of the pre- and postsynaptic neurons. D) ability of the postsynaptic cell to use retrograde messengers such as nitric oxide (NO) to communicate with the presynaptic cell.

 Simultaneous activity of several synapses on the same postsynaptic neuron during LTP is referred to as A) sensitization. B) facilitation. C) cooperativity. D) potentiativity.

 NMDA receptors ___________ when the nearby membrane is not depolarized. A) allow both sodium and calcium to enter the cell B) are blocked by a molecule of calcium C) are blocked by a molecule of magnesium D) allow potassium to leave the cell

 LTP A) always involves the neurotransmitter glutamate and only occurs in the hippocampus. B) always involves the neurotransmitter glutamate and occurs in many areas of the central nervous system. C) involves a variety of neurotransmitters but only occurs in the hippocampus. D) involves a variety of neurotransmitters and occurs in many areas of the central nervous system.

 The process of __________ is probably dependent on LTP. A) language learning B) spatial learning C) formation of flashbulb memories D) habituation

 Typical mice with unimpaired LTP A) are unable to form spatial maps. B) form spatial maps that are inaccurate. C) form spatial maps accurately but experience immediate loss of those maps. D) form new maps and can retain them for long periods of time.

 In conditioned fear research with rats, which of the following might be used by the experimenters as a conditioned response? A) working to postpone an electric shock B) increased salivation C) freezing D) increases in working for food
