Nervous System MCQs

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…

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…

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

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)

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

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…

A. Parallel and visual processing of incoming information

B. Independent and neuronal processing of incoming information
