LIST 3 TRADITIONAL METHODS OF RESEARCH
|
1. USE NON-HUMANS TO DAMAGE BRAIN TO SEE THE CHANGES IN FUNCTION
(COMPARE WITH NONHUMANS WHO DO NOT HAVE THE LESION) 2. CLINICAL - ASSESSES HUMANS WHO HAVE BRAIN DAMAGE WITH NO BRAIN DAMAGE AND HOW IT AFFECTS BEHAVIOR 3. BRAIN MAPPING |
|
|
WHAT IS BRAIN MAPPING
|
INVOLVES STIMULATING THE BRAIN TO DETERMINE THE REACTIONS. BEEN DONE IN NEURO SURGERY
THIS ALLOWS NERO SCIENTISTS TO BUILD A MAP OF THE CEBERAL CORTEX AND ITS SPECIFIC SENSORY AND MOTOR FUNCTIONS |
|
|
TECHNOLOGOY TO STUDY BRAIN
|
EEG, MICROELECTRODE IMPLANTS, CT SCANS, MRI
FMRI, PET |
|
|
WHAT ARE EEG RECORDINS
|
REFLECT THE ELECTRICAL PART OF NEURAL TRANSMISSION. (REVELS SIZURES, SLEEP STAGES, DISEASE CONDITIONS SUCH AS TUMORS)
|
|
|
WHAT ARE MICTOELECTRODE IMPLANTS
|
ALLOWS RESEARCHERS TO STUDY THE ACTIVITY OF SINGLE NEURON
(THIS TECHNIQUE HAS ALLOWED RESEARCHERS TO STUDY THE RESTING AND ACTION POTENTIALS OF SINGLE NEURONS) TECNIQUE IS INVASIVE IT HURTS AND DAMAGES THE SINGLE NEURON |
|
|
WHAT ARE CT SCANS
|
3 DEMENSIONAL PICTURE OF THE BRAIN
EXCELLANT DX TOOL BUT DOES NOT REVEAL FUNCTION |
|
|
MRI
|
MAGNETIC RESONANCE IMAGING OF THE BRAIN
EXCELLENT DX TOOL BUT DOES NOT REVEAL FUNCTION |
|
|
FMRI
|
FUNCTIONAL MAGNETIC RESONANCE IMAGING
|
|
|
FMRI WHAT DOES IT USE
|
USES THE MAGNETIC PROPERTIES OF BLOOD TO IMAGE WHAT PARTS OF THE BRANI ARE WORKING MORE THAN OTHER PARTS OF THE BRAIN (NO DAMAGE TO BRAIN)
|
|
|
WHAT TWO TECNIQUES WILL CONTINUE TO CHANGE NEUROSCIENCE
|
FMRI AND PET
|
|
|
WHAT IS USED TO MONITOR THE BRAIN WHEN SOMEONE LISTENS TO A VOICE, THINKS ABOUT MATH PROBLEMS EXPERIENCES FEAR?
|
FMRI
|
|
|
PET IS
|
POSITRON EMISSION TOMOGRAPHY
|
|
|
WHAT IS PET
|
USES THE DECAY OF RADIOACTIVE MATERIAL TO IMAGE THE BRAIN
|
|
|
WHAT DOES THE PET ALLOW REASEARCHERS TO DO
|
IMAGE A LIVING FUNCTIONAL HUMAN BRAIN BUT DOES NOT EXPOSE TO RADIATIONS WHICS IS A DISAVANTAGE
|
|
|
WHICH HAS BETTER RESOLUTIONS OF PICTURES
|
FMRI
|
|
|
WHAT HAVE ALLOWED THE DEVLOPMENT OF COGNITIVE NEUROSCIENCE, ONE OF THE NEW BRANCHES OF BIO-PSYCH
|
PET AND FMRI
|
