Neuroscience Quiz

The neural tissue covering the cerebral hemispheres is called the

• cerebrum.

• cerebral cortex.

• meninges.

• association cortex.

Experimental research using ablation involves _____ a brain structure or area to observe the effect on behavioural or mental functions.

• removing

• stimulating

• inhibiting

• stimulating and/or inhibiting

The term contralateral in relation to brain function means

• contradictory function.

• interconnected.

• opposite side.

• interdependent.

The brain structure that is most prominently involved in regulation of eating, drinking and body temperature is the

• cerebellum.

• reticular formation.

• thalamus.

• hypothalamus.

The brain structure that coordinates bodily movements to ensure precise and smooth execution is the

• cerebellum.

• cerebrum.

• medulla.

• hypothalamus.

The brain area primarily involved in regulating bodily activities that are vital for survival is the

• cerebral cortex.

• hindbrain.

• forebrain.

• midbrain.

Which of the following statements about hemispheric function is correct?

• The left and right hemispheres control voluntary movements on both sides of the body and receive sensory information from both sides of the body.

• The left and right hemispheres exchange and process sensory information before deciding which side of the body requires control of voluntary movements.

• The right hemisphere controls voluntary movements on the right side of the body and receives sensory information from the right side of the body.

• The left hemisphere controls voluntary movements on the right side of the body and receives sensory information from the right side of the body.

An advantage of a PET scan when compared with a CAT scan is that

• a PET scan provides information about brain movement, whereas a CAT scan provides only structural information.

• a PET scan provides information about brain activity, whereas a CAT scan provides only structural information.

• a PET scan provides magnetic brain images whereas a CAT scan provides computerised cross-sectional brain images.

• a PET scan is non-invasive, whereas a CAT scan is invasive because radiation is used.

Which brain structure screens then redirects incoming sensory information to the relevant cortical area?

• thalamus

• hypothalamus

• medulla

• cerebrum

The brain vs heart debate

• has its origins with the development of neuroimaging techniques in the 1970s.

• is about the source of human mental processes and behaviour.

• was first proposed by the philosopher Descartes.

• proposes that both the heart and brain contribute to human mental processes and behaviour.
