Early research on the patterns of behavior observed in people during epileptic seizures advanced the idea that:
A. Seizure were caused by chemical discharges in the brain B. The cortex can be surgically removed to reduce seizures C. Brain regions have highly specialized functions D. (b) and (c)
Communication among the neurons requires two main activities. Electrical signals which are generated by________and chemical signals which are generated by______.
A. Resting potentials, neurotransmitters B. Neurotransmitters, axon potentials C. Neurotransmitters, depolarization D. Axon potentials; neurotransmitters
If we surveyed a sample of neuroscientists, which part of the brain would they report as most preferable to lose?
A. A cubic centimeter of glial cells because the damage would be less disabling B. A cubic centimeter of subcortex because the damage would be less disabling C. A cubic centimeter of spinal cord because the damage would be less disabling D. A cubic centimeter of cortex because the damage would be less disabling
Which one of the following do we know to be true about inhibitory neurotransmitters?
A. Inhibitory neurotransmitters increase the excitability of a cell B. The classic inhibitory neurotransmitter is glutamate C. Increasing chloride ion flow into the interior of the cell decreases the cell’s negativity D. Increasing the cell’s negativity is called hyperpolarization
Neurotransmission, and thus brain function, can be disrupted by:
A. Antagonists B. Agonists C. A and B D. Synapses
Regarding the electrical activity of neurons, which of the following is?
A. Neurons are integrators; they can have a vast number of different inputs, but they produce just a single output signal, which they transmit to their targets B. There is a small voltage difference between the inside and the outside of the neuron in it resting state, known as the action potential C. The inputs … Read more
Which of the following statements regarding the NMDA receptor is?
A. The NMDA receptor is a particular subtype of glutamate receptor B. Sodium entry into cell is one of the triggers for the development of LTP C. NMDA-dependent LTP can only develop in a cell that has been depolarized and then receives a further input D. Experiments have show the blockade of the NMDA receptor … Read more
Long-term potentiation and long-term depression are processes demonstrating that:
A. Experience can modify a neuron’s responses B. Experience can modify a person’s potential C. Experience can modify a person’s mental health D. Experience cannot modify a neuron’s responses
Which of the following assertions about modularity in the brain is accurate?
A. Different aspects of a visual stimulus appear to be analysed by different modules in the brain B. It is impossible to use an evolutionary explanation for modularity in the brain C. Both (a) and (b) D. Neither (a) nor (b)
