The definition of bulk magnetisation (M)
What is the vector sum of all spin ups and spin downs
The nuclear imaging technique that uses a collimator
What is SPECT
How we would get the best signal for electrophysiology (3 things)
What is pyramidal neurons, same direction, post synaptic potentials
the two types of coils used in TMS
what is round coils and double / figure 8 coils
what is the surface of the cerebral cortex and the scalp
The purpose of B1
The tracer for perfusion imaging in SPECT
What is Tc99m-HMPAO
non physiological artefact in eeg
what is 50Hz AC from electrical equipment
what is repetitive TMS
what is a channel
what is the midpoint of sources and detectors
The most efficient way to apply B1 to achieve resonance
What is to keep B1 on all the time but rotate it with M so it always pushes in the right direction (larmor?)
what happens in a coincident event
What is 2 photons are detected within a given timeframe and a line of response is drawn between them
The meaning of a model based approach to reducing interference
what is defining what interference means before collecting data, using mathematical models
the factors of the motor system we can measure with TMS
what is motor threshold, cortical silent period, input/output curve
what is neurovascular coupling
what is the active process linking local neuronal activity to an orchestrated increase in local blood flow
The events of a spin echo
What is after the rf90 pulse we apply an rf180 pulse which flips the directions causing them to move back together (instead of further apart)
How DATscans are normalised
What is counts in striatum / sounds in background = striatal binding ratio
example of interference a shield room will not eliminate in MEG
what is the piccadilly line
the minimum requirements for tDCS to be effective
what is 3 minutes of 0.6mA
how light separators work
what is they use prisms to disperse light and diffraction gratings with periodical microscopic ridges to diffract light
the direction of B0
What is Longitudinal (z)
The energy of the gamma rays produced in annihilation
What is 511KeV
2 examples of ERPs
what is N400/P600 - grammatical inconsistencies and mismatch negativity - deviant sound
how TMS can be used to assess neuroplasticity
the purpose of the ucln algorithm
what is connecting different intensities of light over time with the concentrations of the chromophores depending on how many wavelengths of light you have
