STUDY
PLAY
brainstem
begins where the spinal cord swells as it enters the skull
brainstem
responsible for automatic survival functions
brainstem
includes 3 strucutres: the medulla, pons & midbrain
medulla
located in the base of the brain stem
medulla
controls heartbeat & breathing
medulla
"power generator of the brain"
pons
functions as a big relay station
tegmentum
contains numerous nuclei & the reticular formation. located in the mid brain
tectum
includes the Superior Collculus & the Inferior Colliculus. located in the mid brain
inferior colliculus
rapidly locates objects auditorally in the environment
superior colliculus
rapidly locates objects visually in the environment
reticular activation system
a nerve network in the brainstem
reticular activation system
plays an important role in controlling arousal from the brainstem to the higher brain structures
thalamus
located on top of the brainstem
thalamus
directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum & the medulla
thalamus
everything passes through here at some point
cerebellum
attached to the rear of the brainstem
cerebellum
helps coordinate voluntary movement and balance
cerebellum
important role for timing movements, possibly organization of actions
limbic system
a system of neural structures at the border of the brain stem & cerebral hemispheres
limbic system
associated w/ emotion such as fear and agression and drives such as those for food and sex
limbic system
includes 3 structures: hippocampus, amygdala and the hypothalamus
amygdala
in the limbic system and is linked to emotion
hypothalamus
located below the thalamus
hypothalamus
directs eating, drinking and body temperature
hypothalamus
helps govern the endocrine system via the pituitary gland
hippocampus
structure in the limbic system that is critical for creating new long term memories
hippocampus
located right below the temporal lobe
hippocampus
plays a role in navigation
basal ganglia
composed of the caudate nucleas, puamen and the globus pallidus
basal ganglia
controls the release & contraction of muscles
cerebrum
another name for the cerebral cortex
cerebral cortex
another name for the cerebrum
cerebral cortex
the body's ultimate control & information processing center
cerebral cortex
divided into 4 lobes: frontal, parietal, temporal and occipital
cerebral cortex
intricate fabric of interconnected neural cells that covers the cerebral hemispheres
occipital lobe
contains the primary visual cortex; basic shape & color identification
temporal lobe
contains the auditory cortex
temporal lobe
very important for memory; object and face recognition & development of long term memories
temporal lobe
located above the hippocampus
parietal lobe
contains the somatosensory cortex
parietal lobe
important for integrating visual infor into a solid, 3D representation of the environment
frontal lobe
allows us to plan, organize & direct our actions coherently
frontal lobe
plays a critical role in language processing, emotion control, memory consolidation & social behavior
frontal lobe
contains the primary motor cortex
frontal lobe
important for personality formation
