Question 1

Tomography

Answer 1

calcium plays a big role. the spatial resolution is in mm, morphological information.

Question 2

Cerebral circulation: oxygen consumption

Answer 2

100g / 3.35 ml/min.

90% of energy metabolism: oxydative breakdown of glucose. 10% anearob glycosis.

Question 3

Blood flow

Answer 3

100g/min = 50 ml

Question 4

1842 Christian Doppler

Answer 4

Ultrasound. Defined variables: 1) shape of pulse wave 2) direction of flow 3) speed of flow

Question 5

PET study

Answer 5

injected isotopes. its great for studying metabolism but its bad because of the spatial and time resolution.

Question 6

FDG PET

Answer 6

measures glucose uptake: the higher the more active.

Question 7

FMRI

Answer 7

functional magnetic resonance imaging: deoxihaemoglobin has paramagnetic properties.

Question 8

Transcranial Magnetic stimulation

Answer 8

Faraday: electromagnetic field is generated in a coil

Question 9

NIRS

Answer 9

Near infrared spectroscopy.

Question 10

NIRS basic principle

Answer 10

NIRS measures the of oxigenization of living tissue
ABSORPTION IS MOSTLY DUE TO HEMOGLOBIN.
ADVANTAGE:
Good temporal and spatial resolution.
DISADVANTAGE:
expensive
small cortical area can be investigateds
