Brain and Behaviour practice MCQs

What did Otto Loewi’s classical experiments on the isolated frog heart demonstrate?

• Chemical transmission in axons

• Chemical transmission across the synapse

• Electrical transmission in axons

• Electrical transmission across the synapse

Where is the primary motor cortex located?

• Precentral gyrus

• Postcentral gyrus

• Central sulcus

• Central fissure

An action potential is:

• An excitatory potential in dendrites

• An electrical spike in axons

• Around -70 mV

• A trans-synaptic current

A neurotransmitter is:

• A chemical which stimulates action potentials

• A chemical which transmits signals in the dendrites

• A chemical which transmits signals across the synaptic cleft

• A chemical which transmits signals along the axon

Baddeley (1973) found that performance would suffer when completing 2 visual-based tasks simultaneously, but not when completing a visual and verbal task simultaneously. This has been considered as evidence in support of:

• Serial position effect

• Levels of processing theory

• Working memory model

• Multi-store model of memory

Patient KF had a higher rate of forgetting of auditory information compared to visual stimuli. Which model of memory does this contradict?

• Levels of processing

• Theories of forgetting

• Multi-store model of memory

• Working memory model

A patient is able to accurately recognise an object’s shape and size, but is unable to accurately position their hand to reach for the object. Which perceptual stream does this patient have damage to?

• The dorsal stream

• The ventral stream

• The Broca’s area

• The Wernicke’s area

Which of the following correctly describes the function of rods and cones in the process of visual perception?

• Rods give information about visual details such as colour while cones are sensitive to movement

• Rods are sensitive to movement while cones give information about visual details such as colour

What is 'confirmation bias'?

• Focusing on evidence consistent with hypotheses, ignoring contradictory information

• Basing judgments on the first piece of information available

• The belief that if something happens more frequently than normal during some period, it will happen less frequently in the future and vice versa

• Reliance on examples that come to mind first

Patient RD is able to comprehend the language of others, but has difficulty in producing speech, which is characterised by slow, non-fluent and syntactically incorrect sentences, e.g., “Cat furry is mine”. This is an example of which type of aphasia?

• Wernicke's aphasia

• Broca's aphasia
