Chapter 2 - Brain Structures and Imaging Techniqhes Flashcards
What does a Electrical Recording (EEG) do?
Records Electrical Recording of brain
Useful in Sleep Studies
What is a PET?
Radioactive tracer injected into brains circulation and can be tracked externally to study the brain
What is a fMRI and what does it do?
MEasures changes in blood flow and oxygenation in the brain
Creates images of brain nativity
Used to study the brain during specific tasks
Ex: what part of brain is used during math problems etc
What does “Old Brain” Mean?
Oldest Evolutionary Parts of the brain linked with
- Basic Survival Functions
- Instinctual Behaviors
What does the “Old Brain” consit of?
Brainstem
Cerebellum
Subcortical Structures
What does “New Brain” Mean?
Newest Evolved parts of brain linked with
- Higher Cognitive Functions
- Significant portion of brains volume
What are parts of the “New Brain” ?
Outermost Layer of Brain
Four Lobes
- Frontal Lobe
- Occipital Lobe
- Parietal Lobe
- Temporal Lobe
What are the Brain Stem Functions?
Collects sensory signals from the body
Sends Signals down from the brain to create movement and regulate vital functions
What is the Function of the Cerebellum?
Supports variety of functions
Coordination
Precision
Balance
Accurate Timing
What are the Subcortical Structures?
-Basal Ganglia
- Thalamus
- Hypothalamus
- Hippocampus
- Amygadala
What does Basal Ganglia do?
Cordinates movement
What does Thalamus Do?
Relay center for all senses (Except Smell)
What does Hippocampus do?
Encoding and Retrival; Thinking about the future
What does the Amygadala do?
Expierence of emotion (especially fear)
What does the Hypothalamus do?
Releasing horomones. Regulating body temperature
