PAPER 2026 COMPLETE Q&A
GUARANTEED TO PASS
⩥ What five things must be used to evaluate localisation of function?
Answer: Brain scan evidence, neurological evidence, case study
evidence, Lashley's research and plasticity and the equipotentiality
theory.
⩥ Synaptic pruning. Answer: As we age, rarely used connections are
deleted and frequently used connections are strengthened.
⩥ Axonal sprouting. Answer: Undamaged axons grow new nerve
endings to reconnect neurons whose links were injured or severed.
⩥ Recruitment of homologous areas. Answer: Regions on opposite sides
of the brain take on functions of damaged areas.
⩥ Functional recovery. Answer: Form of plasticity. Following damage
through trauma, the brain's ability to redistribute/transfer functions
performed by damaged areas to other, undamaged areas.
, ⩥ Neural plasticity. Answer: Describes the brain's tendency to change
and adapt - functionally and physically - resulting from experience and
new learning.
⩥ What is the central nervous system (CNS)? Answer: Consists of brain
and spinal cord; origin of all complex commands and decisions.
⩥ What is the peripheral nervous system (PNS)? Answer: Sends info to
CNS from outside world, transmitting messages from CNS to muscles
and bodily glands.
⩥ Define hemispheric lateralisation.. Answer: Certain mental processes
and behaviours are controlled or dominated by one hemisphere rather
than the other (as in the example of language).
⩥ Corpus callosum. Answer: A band of neural fibres that connects the
left and right hemispheres of the brain.
⩥ Split-brain studies.. Answer: Corpus callosum cut in patients with
severe epilepsy, allowing researchers to investigate the extent to which
brain function is lateralised.
⩥ Describing what you see.. Answer: Pictures shown to RVF could be
described but not those to LVF because no language centres in left
hemisphere (connected to RVF).
