[PHYSIOLOGICAL] Biological - Neurochemicals

Question 1

[NEUROCHEMICALS & BIOCHEMICALS]

Explain the function of Neurochemicals

Answer 1

Chemical messages that are passed through neurons
Responsible for the activation of behavioural patterns and tendencies in specific areas of the brain
Carry messages throughout the body

Question 2

[NEUROCHEMICALS & BIOCHEMICALS]

Explain the function of hormones

Answer 2

Controlled by the endocrine system
travel through the blood stream

Question 3

[NEUROCHEMICALS & BIOCHEMICALS]

Explain how the brain is effected

Answer 3

Effected by diet

Question 4

[NEUROCHEMICALS & BIOCHEMICALS]

What foods can help to raise serotonin & dopamine

Answer 4

Fatty fish
Dark chocolate
Turmeric
Organic Green Tea
Fermented Foods like kimchi

Question 5

[NEUROCHEMICALS & BIOCHEMICALS]

Explain how diet can help neurochemical transmission & Adrian Raine’s research

Answer 5

Omega 3 - impacts healthy cell growth and neural connections

Experiment where he gave 100 children a fruity dribk with omega 3 for 6 months alongside a control group

Behaviour of children improved in the Omega 3 group showing a reduction in aggression - continued 6 months after experiement

Regular dose of Omega 3 in childhood can reduce chance of criminality

Question 6

[NEUROCHEMICALS & BIOCHEMICALS]

Explain how blood sugar levels can cause criminality

Answer 6

Low blood sugar levels can cause aggressive reactions
Research shows a link between low blood sugar levels and alcohol abuse as drinking large quantities of alcohol can induce hypoglycaemia and increase aggression

Question 7

[NEUROCHEMICALS & BIOCHEMICALS]

Explain how biochemical substances can cause criminality

Answer 7

Their effects on brain chemistry and mental processes can cause criminal behaviour

E.g: Sex hormones, blood sugar levels and substance abuse

Question 8

[NEUROCHEMICALS & BIOCHEMICALS]

Explain the function of serotonin

Answer 8

Regulates signals between neurons and is believed to control mood. Can also prevent behaviours.

Question 9

[NEUROCHEMICALS & BIOCHEMICALS]

Explain dopamine’s link to criminal behaviour

Answer 9

Linked with aggression, addiction and substance abuse

Question 10

Weakness

Answer 10

• Everyone’s neurochemical levels are different making it difficult to find balance for you
