How to study the brain

Question 1

where are place cells found

Answer 1

hippocampus

Question 2

what are LFP recordings

Answer 2

local field potential recordings - recording electrical potentials generated by many neurons

Question 3

what is an EEG

Answer 3

electoencephalography - records electrical activity in the brain, records spontaneous activity and event-related (evoked) activity

Question 4

what is an MEG

Answer 4

magnetencephalography - measures small magnetic-field changes - better spacial resolution than EEG

Question 5

What is an MRI

Answer 5

magnetic resonance imaging, strong magnetic fields align hydrogen nuclei

Question 6

what is functional MRI of the brain

Answer 6

based on changes associated with metabolic and cerebral-blood-flow changes - most common method - BOLD MR signal

Question 7

What is a PET

Answer 7

positron emission tomogrpahy - injection of radioactive tracers - tracers followed around the brain
can see chemical neurotransmission and brain activity
