Unit 3B Flashcards
Destroying certain brain tissues
Lesion
Records electrical activity in our brains; waves are measured by electrodes on scalp
EEG
Series of x-rays put together
CT scan
Visual display of brain activity that detects where radioactive glucose goes
PET scan
Produces computer generate brain tissue; magnetic fields and radio waves
MRI
Reveals bloodflow through brain; shows brain function
fMRI
What makes up the brainstem?
Pons and medulla
Controls when we sleep
Pons
Responsible for automatic survival functions
Brainstem
Controls heartbeat and breathing
Medulla
Controls arousal and filters sensory info
Reticular formation
Directs messages to sensory receiving areas except smell
Thalamus
Controls balance, voluntary movement, judgement, emotions, time
Cerebellum
What makes up the limbic system?
Amygdala, hypothalamus, hippocampus
Associated with emotions and drives
Limbic system
Linked to emotions (fear and anger)
Amygdala
Controls the pituitary gland; linked with emotion and reward
Hypothalamus
Body’s ultimate control and information processing center
Cerebral
Cells in the nervous system that nourish, protect, support neurons
Glial cells
Associated with speech, movement, judgemet, personality, planning
Frontal lobe
Receives sensory input for touch and body position
Parietal lobe
Associated with receiving info for vision
Occipital lobe
Associated with receiving auditory information
Temporal lobe
Sends voluntary movements
Motor cortex
Registers and processes body touch and movement sensations
Sensory cortex
Where is the motor cortex located?
Frontal lobe
Where is the sensory cortex located?
Parietal lobe
Involved with speaking, thinking, remembering, learning; higher knowledge areas
Association areas
How do areas coordinate to produce speech?
- Registers in visual area
- Relayed to angular gyrus to make an auditory code
- Received by Wernicke’s area
- Sent to Broca’s area
- Controls the motor cortex as it creates pronounced words
Impairment of language due to the damage of Broca’s and Wernicke’s
Aphasia
Where is the Broca’s area located?
Frontal lobe
Where is the Wernicke’s area located?
Temporal lobe
Controls language expression; directs muscle movement in speech
Broca’s area
Proposed that damage to the left frontal lobe would disrupt speaking
Paul Broca
Controls comprehension and expression
Wernicke’s area
Claimed that after damage to left of the temporal lobe that people would speak meaningless words
Karl Wernicke
Ability to change by recognizing after damage or building new pathways based on experience
Plasticity
Formation of new neurons
Neurogenesis
Connects and communicates left and right hemispheres
Corpus callosum
Isolating the brain hemispheres by cutting fibers connecting them
Split brain
Studied of the neural basis of mind with primary responsibility for initiating human split-brain research. In his subsequent work he has made important advances in our understanding of functional lateralization in the brain and how the cerebral hemispheres communicate with one another.
Michael Gazzaniga
Scientist who won a Nobel Prize for work with split brain patients
Roger Sperry
Hemisphere involved with language, logic; processing and thinking
Left
Hemisphere involved with nonverbal, spatial
Right
Awareness of ourselves and the environment
Conscious
Study of brain activity linked with cognition
Cognitive neuroscience
Information is processed on separate conscious and unconscious tracks
Dual processing
