UNIT 2: BIOLOGICAL BASES OF BEHAVIOR Flashcards
- LOBES OF THE BRAIN
Frontal Lobe
Executive function, higher level cognition
Parietal Lobe
Sensory Information
Occipital Lobe
Vision
Temporal Lobe
Sense of hearing/meaningful speech.
STRUCTURES OF THE BRAIN
Corpus Callosum
Connects two hemispheres
Medulla
Life sustaining functions, breathing, heart rate, blood pressure.
Cerebellum
Control coordination “balance”/voluntary movements.
Hypothalamus
Releasing hormones (regulate homeostasis of the body).
Hippocampus
Formation of memories
Amygdala “Fear Center”
Processing emotion and survival responses.
Neuroplasticity
Is the brain’s ability to constantly change both the structure and function of many cells in the brain.
Split Brain
Is the two hemispheres of the brain can’t communicate with each side (researched by Sperry and Gazzaniga).
Broca’s Area
Speech production
Wernicke’s Area
Comprehension of speech
Motor Cortex
Voluntary movement
Somatosensory Cortex
Receives and processes sensory information.
THE NERVOUS SYSTEM
Body’s communication network.
Central Nervous System
Brain and the spine
Peripheral Nervous System
Sensory nerves outside brain/spinal cord.
Somatic Nervous System
Voluntary moment from your brain to your muscles.
Autonomic Nervous System
Involuntary and unconscious actions (breathing, blood pumping, and etc).
Sympathetic Nervous System
Emergency response system “Fight, Flight, or Freeze”
Parasympathetic Nervous System
Calm a person “rest and digest”
