Brain Flashcards
EEG
Device that detects, amplifies and records electrical activity of the brain. To diagnose disorders such as epilepsy and Parkinson’s disease. Also identify brain waves patterns of people suffering depression
CAT
Iodine based substance injected in vein of persons arm or hand. CT scan reveal location and effects of stroke, injuries, tumours and other brain disorders. Doesn’t provide info on structure and function of brain.
MRI
Strong magnetic field to construct image of brains structure. Distinguish cancer and non-cancerous cells. Pinpoint weakness in blood vessels in the brain. Detect lesions or brain damage associated with epilepsy. Also detect spinal cord abnormalities in children and degenerative diseases of the central nervous system.
fMRI
Detects changes in oxygen levels in the blood flowing throughout the brain dead combines the data to create an enhanced 3-D representation of the active brain. Psychologists use fMRI scans to pinpoint which brain area and structure is being used while the person is using cognitive and physical activity
Parietal lobe
Bodily sensations, eg. Touch, temp and pain relating to muscle and joint movement
Gage
Frontal lobe was i paled with iron rod. Gages personality, behaviour and temperament was affected. Led teasers hers to believe the frontal lobe was involved in personality
Neutron
A neuron is a cell that receives and transmits information.
Somatic nervous system
PNS that transmits sensory info received from sensory info receptor cells inwards towards the CNS, motor messages from CNS to the body’s skeletal system
Autonomic
PNS that’s transmits motor messages from the brain to the body’s internal organs and glands, which results involuntary activity of internal organs and glands, and transmits messages back to the brain about the activity level of those organs and glands.
Brain structure and lobes
Forebrain
Midbrain
Hindbrain
Lobes Parietal lobe Frontal lobe Occipital lobe Temporal lobe
