(83 cards)
Describe some tools scientist use to explore the brain/mind connection
Tools of discovery
Brain structures determine our
Abilities
Damage to one side of the brain often causes paralysis on the bodies _______ side
Opposite
Others linked vision problems with damage to the ______ of the brain
Back
Speech problems with damage to the
Left front brain
Larger electrodes attached to the scalp to ease drop on the chatter about billions of neurons is a
EEG (electroencephalograph)
Tracks the brains favorite food, sugar glucose. PET scan’s hotspot show which brain areas are most active as a person sells math problems, looks at images of faces, or daydreams.
PET (positron emission tomography)
Scans capture images of brain structures by briefly disrupting activity in brain molecules.
MRI (magnetic resonance imaging
Tracks excessive images of brain tissue to show brain function
fMRI scan
Traxxas radioactive glucose to reveal brain activity
PET scan
Uses magnetic field and radio waves to show brain anatomy
MRI scan
A special application of MRI also reveals the brain functions.
fMRI
The brains oldest and innermost region is the _____. It begins where the spinal cord swells slightly after entering the skull.
Brainstem
This Slight swelling is the
Medulla
The _____, including the medulla and pons, is an extension of your spinal cord. The ___ is attached to its top. The reticular formation passes through both structures
Brainstem, thalamus
Just above the medulla sits the ____ , A brainstem area that helps coordinate movements. Helps relay messages between the cerebellum and the cortex to help coordinate movement
Pons
The ____ brain controls the ____ side of the body, and vice versa
Right, left
___ is one of the brains many surprises
Cross wiring
Sitting at the top of the brainstem is the
Thalamus
This joined pair of egg shaped structures acts as the brain’s sensory control center.
Thalamus
The Thalamus receives information from all your senses except ____.
Smell
Inside of the brainstem, between your ears, lies your _____. This neuron network extends upward from your spinal cord, through your brain stem, and into your thalamus helps control arousal
Reticular (“netlike”) formation.
At the rear of the brainstem is the ____ meaning “little brain”, which is what it’s too wrinkled has resemble. This baseball sized structure plays in important role in a lot that happens just outside your awareness. Voluntary movements.
Cerebellum
Helps process and store memories for things we cannot consciously recall, such as how we ride a bicycle. If you injure or Drug this with alcohol, you will have trouble walking, keeping your balance, or shaking hands. Movement and balance
Cerebellum
