Term
spinal reflex
Definition
A simple reflex that can be integrated within the spinal cord without input from the brain
Term
Cerebrum
Definition
processes olfactory information, also it allows reasoning and cognition.
Term
cerebellum
Definition

devoted to movement and balance

Term
diencephalon
Definition
Brain portion between brain stem and cerebrum, consisting of thalamus and hypothalamus
Term
gray matter
Definition
Unmyelinated Nerve cell bodies, dendrites, and axon terminals
Term
white matter
Definition
Central nervous system tissue composed primarily of myelinated axons
Term
tract
Definition
Bundles of axons in the CNS, generally with a common origin and destination
Term
primary somatic sensory cortex
Definition

(somatosensory cortex)

 

Termination point of skin, musculoskeltal system and vicera.

Term
primary motor cortex
Definition
Regions of the frontal lobe that coordinate skeletal muscle movements
Term
suprachiasmatic nucleus
Definition

Region of the hypothalamus believed to be the center for the biological clock
Term
anterograde amnesia
Definition
Inability to remember newly-acquired information
Term
Wernicke's area
Definition
One of the speech centers of the brain
Term
Broca's area
Definition

Speech center in the frontal lobe
Term
receptive aphasia
Definition
Inability to understand spoken or visual information due to damage to Wernicke's area
Term
expressive aphasia
Definition
Inability to speak coherently as a result of damage to Broca's area
Term
Hypothalamus
Definition
behavioral drives/ controls homeostasis by controlling endocrine and autonomic function
Term
Pituitary gland/ Pineal gland
Definition
endocrine glands located in the diencephalon
Term
Basal Ganglia
Definition
control movement
Term
Lymbic system
Definition

link between cognitive function and emotional responses.

 

Includes:

 

Amydala and cingulate gyrus: linked to emotion and memory

 

hippocampus: learning and memory

Term
Cerebral Cortex
Definition

high brain function/ reasoning originate here

 

Three specialized areas: sensory areas, motor areas, association areas

Term
Primary Sensory Cortex
Definition

in the sensory area of cerebral cortex.

 

processes touch and temperature

Term
Association areas
Definition

integrate sensory information into perception

 

Perception is the Brain's responce to stimuli

Term
Behavioral State system
Definition
controls arousal and modulates cognitive and modulates the sensory and cognitive systems.
Term
diffuse modulatory system
Definition
influence attention, motivation, wakefullness, memory, motor control, mood, and metabolic homeostasis
Term
reticular activating system
Definition
keeps the brain concious
Term
Associative Learning
Definition
When two stimuli are associated with one another
Term
Nonassociative Learning
Definition
Include immitative behaviours, such as learning language.
Term
Habituation
Definition
decreased response to a stimuli that is repeated over and over
Term
Sensitization
Definition
exposure to a noxious or intense stimuli creates enhanced response to subsequent exposure.
Term
Reflexive memor
Definition
does not require concious process for its creation or recall
Term
Declarative Memory
Definition
uses higher level cognitive skills for formation and requires concious attention for its recall
