MRI

A
  • Magnetic fields are generated that align hydrogen atoms – MRI uses the alignment to localize tissue precisely
  • very precise, detailed picture of the brain

A

role in movement, auditory perception, emotional processing

18
Q

Midbrain

A

Tectum

Tegmentum

19
Q

Tectum

A

a. Superior Colliculi: eye movements and visual reflexes
i. Eyes are your superior sense
Inferior Colliculi: auditory integration

20
Q

Tegmentum

A

a. Red Nucleus: Motor Control
i. Red – stop sign – motor control
b. Substantia Nigra: reward related behaviours
Substance addiction – dopamine rush – reward seeking

21
Q

Forebrain

A

Harry Potter Touches A Horcrux

22
Q

Hypothalamus

A

4 f’s, fight, flight, feeding, reproduction

HYPE – when you get hyped up, heart rate speeds up – need to be alert

23
Q

Pituitary

A

a. Anterior: releases stimulating hormones to regulate other important endocrine glands
b. Posterior: releases oxytocin and vasopressin
A is before P, anterior is rostral to posterior

24
Q

Thalamus

A

processes and relays the information selectively to areas of cerebral cortex

- Language
- Inhibition
- Manipulation of items in short term memory
33
Q

responsible for visual processing

- Sounds like optical, eyes

36
Q

Brain Lateralization

A

function specialized to one side of the brain

37
Q

damage in a particular area of the brain but not other, produces a specific behavioural defect

38
Q

Broca’s Area

A

vital for motor production of speech

39

41
Q

Split Brain Syndrome

A

having 2 independently operating hemispheres
