The Brain & Limbic System Flashcards
Unit 2
The “little brain” that’s attached to the rear of the brainstem
Cerebellum
Helps coordinate voluntary motor movements, posture, and balance
Cerebellum
Experimented with rats in enriched and impoverished environments
Rosenweig
Stimulates infants’ cerebellums
Rocking
What equals a larger brain and increased blood supply
More stimulation
Oldest part of the brain beginning where the spinal cord swells and enters the skull
Brainstem
Responsible for automatic survival functions
Brainstem
“Inner Chamber” or sensory switchboard (except smell)
Thalamus
Relays info between lower brain centers and cerebral cortex
Thalamus
Transmits replies to the medulla and cerebellum
Thalamus
Nerve network in the brainstem that controls arousal, attention to incoming stimuli
Reticular Formation
Comas result here
Reticular Formation
Located at the base of the brainstem and controls involuntary movements
Medulla
Bulge in the brainstem between two halves of the cerebellum
Pons
Serves as the bridge and relay station for hindbrain (cerebellum) and rest of the brain
Pons
Controls sleep and basic arousal
Pons
Doughnut-shapes system of neural structures at the border of the brainstem and cerebrum
Limbic System
Associated with emotions and drives for food and sex
Limbic System
Includes the hippocampus, amygdala, and hypothalamus
Limbic System
Smell is routed through here
Limbic System
Controls maintenance functions (The 4 Fs)
Hypothalamus
Linked to emotion and reward
Hypothalamus
Governs the endocrine system responsible for homeostasis
Hypothalamus
Endocrine gland that regulates growth
Pituitary
Consists of two almond-shaped neural clusters linked to the emotions of anger and fear
Amygdala
Deals with learning and memory (including memory processing and remembering recent events)
Hippocampus
The Reward Center (Olds and Milner, 1950s)
Hypothalamus
