relates to whether an action and its consequences are right or wrong

consent obtained from a patient where they fully understand the procedure and its implications

a type of cell division that produces genetically identical cells

a cell that can differentiate into specialised cells

Damage and disease in the human brain, including fMRI and electrical stimulation

Biology

The human nervous system

Neurones and synapses

Human reaction time: practical

The structure and function of a reflex arc

The human eye

Common defects of the human eye

The human brain

Pupils will learn how hormones and glands of the human endocrine system enable us to coordinate and control changes in our bodies.

Pupils learned how substances essential for chemical reactions in living cells, and the products of the reactions, are transported into, around and out of the human body, and the implications of surface area:volume ratio.

This unit explores the structure and function of the nervous system, including the CNS, reflex arcs, and the eye. It covers brain structure, common eye defects, and the challenges in treating nervous system damage. It also addresses ethical considerations.

Coordination and control: the human nervous system

Subjects which particular individuals may be sensitive to, eg, adoption, migration, bereavement or death, divorce, poverty, deprivation.

Depiction or discussion of sensitive content

When embarking on research into the human brain, what should we consider?

The patient may not be able to consent to the research.

The patient may not benefit from the research.

Patient brain function may be severely limited.

The patient may be harmed by the research.

Which of these statements is **not** an ethical issue involved in studying patients with brain damage caused by Parkinson's?

True or false? Stimulation of the brain involves an electrical current being applied.

used to treat long-term conditions such as dementia

involves an implant being placed in the brain

involves a net of electrodes being placed over the head

used to treat long-term conditions such as Parkinson’s and epilepsy

Which of the following are true about deep brain stimulation (DBS)?

electrical impulses are sent to the brain

cause oxygen molecules to oscillate and vibrate

magnetic material cannot go in the scanner

Which of the following is true about Functional Magnetic Resonance Imaging (fMRI) scans?

Neurones are very complex cells and cannot undergo {{}} to create new copies of themselves.

What kinds of issues determine whether an action and its consequences are right or wrong?

What types of cells primarily make up brain tissue?

What is the process of ordinary cell division called?

cells found in the stem of a flowering plant

cells that can differentiate into other types of cell

fMRI imaging uses {{}} radiation to visualise brain activity.

parts of the brain become damaged, affects muscles, e.g. slow movement

associated with an ongoing decline of brain functioning, e.g. memory

involves having a low mood that affects day-to-day living

when the blood supply to part of the brain is cut off
