Psychology is the scientific study of human behavior, mental processes, emotions, and personality. It is an important subject for competitive exams such as PPSC, FPSC, NTS, OTS, KPPSC, BPSC, AJKPSC, CSS, and PMS.

Which of the following statements is NOT true in terms of the repairing damaged brains?

A Adult neurons can sometimes from new connections
B If one input to a target area is lost, the remaining inputs sometimes send out new branches from their axons to colonize the vacant space
C Although transplanted neurons taken from a brain at the right stage of development will grow in an adult host brain, they will not restore normal function
D Transplants of dopamine cell bodies alleviate some of the symptoms of Alzheimer’s disease in human patients
Correct Answer: Transplants of dopamine cell bodies alleviate some of the symptoms of Alzheimer’s disease in human patients

Research on neural grafting techniques to transplant dopamine cell bodies indicate that:

A We cannot repair damaged brains
B We can repair some damaged brains
C We can prevent brain damage
D We can prevent Parkinson’s disease
Correct Answer: We can repair some damaged brains

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)
Correct Answer: Different aspects of a visual stimulus appear to be analysed by different modules in the brain

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
Correct Answer: Experience can modify a neuron’s responses

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 by the drug AP5 prevents the development of LTP
Correct Answer: Sodium entry into cell is one of the triggers for the development of LTP

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 to neurons are tiny amounts of chemical neurotransmitters
D In the steady state neurons, there is an active pumping of ions across the neuronal membrane
Correct Answer: There is a small voltage difference between the inside and the outside of the neuron in it resting state, known as the action potential

Neurotransmission, and thus brain function, can be disrupted by:

A Antagonists
B Agonists
C A and B
D Synapses
Correct Answer: A and B

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
Correct Answer: Increasing the cell’s negativity is called hyperpolarization

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
Correct Answer: A cubic centimeter of cortex because the damage would be less disabling

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
Correct Answer: Axon potentials; neurotransmitters
