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
