|
1. Temporary
2. Permanent |
|
Types of Genetic Manipulation (3)
|
1. Knock-down: less active gene
2. Knock-in: mutation 3. Knock-out: gene taken out (ability to produce protein removed by alteration/replacement of dummy code) |
|
NonInvasive Structural Methods are...what are they? (2)
|
Volumetry Analysis.
1. CT: visualize fractures and leakage, no wh/gr matter diff 2. MRI: exploit NMR and RF. |
|
(2) types of MRI
|
1. T1: White matter BRIGHT, view anatomical structures (familliar brain)
2. T2: Grey matter BRIGHT, view tumors, swelling. |
|
(2) Types of non Invasive Functional Methods
|
1: Direct: measure n. firing
2. Indirect: measure blood flow |
|
(2) Types Direct methods
|
1: EEG- changes in extracellular current, EPSP&IPSP (ERP)
2: MEG- Magnetic field arising from e curent as result of stimulus |
|
ERP
|
Event-related Potentials: AVGing of time-locked segments of EEG to stimulus
|
|
(2) Types of Indirect Methods
|
1. PET- inject of isotopes of glucose or other relevant chemical
2. fMRI- measure areas of blood overcompensation |
|
EEG freq oscillations indicate..
|
different processes.
