Ontology

the process of a individual changing.

What are the three approaches to study the relationship between the brain and behaviour?

Somatic intervention

Behavioural intervention

Correlational studies

What is somatic intervention about?

Changing the structure/function of the brain to see how this changes behaviour?

Independent variable: what we manipulate —> here structure/function)

Dependent variable: what is measured in response to the change in the independent variable —> here behavior)

What is behavioral intervention about?

Changing the behaviour/experience of an individual, to look for resulting changes in the brains structure/function

The opposite of somatic intervention

Indpendent variable: what we manipulate —> here behaviour/experience

Dependent variable: what is measured in response to the change in the independent variable —> here structure/function of the brain

What are correlation studies about?

Are about finding the degree of how a certain bodily meassurement varies in a gived behavioural meassure.

Looks at how much a bodily meassure varies in connection to a behavioural meassure.

The correlation insinuates that the bodily and behavioural measures are connected in some way

Neuroplasticity

The brain will change in order to adapt. The brain will change due to physical behaviour and experiences.

What are the levels of analysis to study the brain?

From “biggest” to smallest:

o   Social level

o   Organ level

o   Neural system level

o   Circut level

o   Cellular level

o   Synaptic level

o   Molecular level

What are the main 5 methods of taking pictures of the brain?

Structural MR

Functional MR

EEG

CT

PET

How does structural MR work and what is it suited to meassure?

Uses a magnetfield that influences the molecules in the brain.

Visualizes the brains structure

How does functional MR work and what is it suited to meassure?

Uses a magnetfield that influences the molecules in the brain.

Visualizes where functions of the brain are located

How does EEG work and what is it suited to meassure?

A hat with electrodes, that meassure electric activity patterns, that the brainneurons produce when at work —> converted to graphs

Shows the brains activity patterns over time and place-period

How does CT work and what is it suited to meassure?

Are exray radiation that created 3D-images of the brain

Is fast to use in urgent situations

How does PET work and what is it suited to meassure?

Inserts radioactive trace elements to the bloodstream, which gather in the brain where their spesific goal, like a molecyl, are.

These elements produce a positron, which meets an electron —> produces gama radiation that a scanner tracks —> creates images of the trace elements localisation in the brain
