Module 11- Studying The Brain Flashcards
Lesion
The word for destroying or removing a very specific part of the brain. Scientists can reveal the impact removing certain parts of the brain and therefore learn more about the specialized neural networks in the brain
EEG (electroencephalograph)
Provided an amplified readout of waves of electrical activity on the brain surface. Measured by electrode placed on scalp
MEG
Measured magnetic fields from the brain’s electrical energy
CT Scan
X-ray photos of the brain to reveal damage
PET
Uses radioactive glucose to show active parts of the brain
MRI
Person’s head is out into magnetic fields and those fields jumble up the electrons and reconfigure the, which emits stuff which is scans to depict the brain’s soft tissues. Usually shows SIZE and SHAPE of brain
fMRI
Compares multiple consecutive MRI scans and watch specific brain areas activate, showing increase blood flow.
Brainstem
The brainstem is oldest and innermost part of brain.
Includes the Medulla, pons.
A CROSSOVER POINT where to nerves from each part of the body connect with the opposite part of the brain
Medulla
controls heart rate and breathing bottom of brainstem
Pons
Movement and sleep
Thalamus
On top of the brainstem.
SENSORY CONTROL; receives info from all senses except smell, and transmits that info to other parts of the brain.
Mostly a CONTROL CENTER, receive and redirects messages
Reticular Formation
Inside the brainstem. Similar to thalamus in that it controls and redirects messages, and specifically helps MULTITASKING
Also controls AROUSAL
Cerebellum
Rear of brainstem; enables non-verbal learning and skill memory. Helps us judge time, moderate emotions, processes SENSORY INFORMATION.
Also helps coordinate voluntary movement like MUSCLE MOVEMENT AND BALANCE
Limbic System
The neural system including AMYGDALA, HYPOTHALAMUS , HIPPOCAMPUS located below the cerebral hemispheres. Associated with various EMOTIONS AND DRIVES
Amygdala
Linked to emotion, aggression and fear.
