biopsychology exam questions with
correct answers

Briefly outline how excitation and inhibition are involved in synaptic transmission (4) -

Answer✔️✔️-• Neurotransmitters can be excitatory or inhibitory (most can be both but

GABA is purely

inhibitory).

• If the neurotransmitter is excitatory then the post synaptic neuron is more likely to fire

an

impulse.

• If the neurotransmitter is inhibitory then the post synaptic neuron is less likely to fire an

impulse.

• The excitatory and inhibitory influences are summed, if the net effect on the post

synaptic

neuron is inhibitory, the neuron will be less likely to 'fire' and if the net effect is

excitatory,

the neuron will be more likely to fire.

Briefly explain one function of the endocrine system (2) - Answer✔️✔️-• To secrete the

hormones which are required to regulate many bodily functions.

• To provide a chemical system of communication via the blood stream.

The electroencephalogram (EEG) and event-related potentials (ERPs) both involve

recording the

electrical activity of the brain.

Outline one difference between the EEG and ERPs - Answer✔️✔️-EEG is a recording of

general brain activity

usually linked to states such as sleep and arousal, whilst ERPs are elicited by specific

stimuli presented to the participant.

Sam is a police officer. She has just started working the night shift and after a week, she

finds that she has difficulty sleeping during the day and is becoming

tense and irritable. Sam is also worried that she is less alert during the night shift itself.

Using your knowledge of endogenous pacemakers and exogenous zeitgebers, explain

Sam's experiences. - Answer✔️✔️-endogenous pacemakers - internal biological rhythms

• exogenous zeitgebers - external factors, eg light

• moving to night shift means pacemakers try to impose inbuilt rhythm of sleep, but are

now out of synchrony with the zeitgeber of light

• disruption of biological rhythms has been shown to lead to disrupted sleep patterns,

increased anxiety and decreased alertness and vigilance.

Outline the structures and processes involved in synaptic transmission.

(Total 6 marks) - Answer✔️✔️-The synaptic cleft; pre and postsynaptic membranes;

postsynaptic receptor sites,

neurotransmitters in vesicles in the presynaptic terminal, release of neurotransmitters

into

the synaptic cleft when stimulated by nerve impulses (action potentials) arriving at the

presynaptic terminal, combination of neurotransmitters with postsynaptic receptors;

postsynaptic effects either excitatory (depolarisation) or inhibitory (hyperpolarisation).

Split brain patients show unusual behaviour when tested in experiments. Briefly explain

how

unusual behaviour in split brain patients could be tested in an experiment.



(Total 2 marks) - Answer✔️✔️-plausible experimental situation / set-up - eg split visual

field, dichotic listening

• plausible stimulus - visual, faces, words, auditory, digits, music etc

• plausible task for patient - verbal or visuospatial response, eg drawing, matching etc.

Briefly evaluate research using split brain patients to investigate hemispheric

lateralisation of function. - Answer✔️✔️-• the disconnection between the hemispheres

was greater in some patients than others

• some patients had experienced drug therapy for much longer than others

• the comparison groups were not considered to be valid as they were often people

with no history of epileptic seizures

• the data were artificially produced as in real life a severed corpus callosum can be

compensated for by the unrestricted use of two eyes

• the research has added to the unity of consciousness debate
