Hemispheres
the localization of some functions in one of the two hemispheres
Lateralization
pathway that connects two hemispheres
Corpus callosum

medulla
what does medulla do
responses to breathing, heart rate and blood pressure
Regulates motor coordination
cerebellum
regulates variety of drives (hunger, thirst, sexual arousal and temperature)
Hypothalamus
Formation of long term movements
hippocampus
involved with fear, aggression, and other emotions
amygdala
A.k.a. fear Center
amygdala
transfers information between the cerebellum and other parts of the brain
pons
contributes to attention and conscious state by filtering incoming stimuli and selectively relaying information
Reticular formation
Relays signals from other parts of the brain to the cerebral cortex and regulates sleep, and consciousness
Thalamus
The wrinkled surface of the cerebrum
Cerebral cortex
largest part of the human brain
Cerebral cortex
This regulates emotions and drives; consists of the thalamus, hypothalamus, amygdala, hippocampus and other structures
The limbic system
is the brains ability to constantly change both the structure and function of many cells in the brain
Neuroplasticity
The process to create new neurons
neurogenesis
Is the two hemispheres of the brain and it can’t communicate with each side
Split brain
Who researched split brain
Sperry and Gazzaniga
Region in the frontal lobe of a person’s dominant hemisphere that controls speech production
Brocas area
region in the temporal lobe of a person’s dominant hemisphere that controls speech comprehension
Wernicke’s area
voluntary movement
motor cortex
recieves and processes sensory information
somatosensory cortex
body’s communication network
the nervous system
brain and the spine
central nervous system
sensory nerves outside brain/spinal cord
Peripheral nervous system
Voluntary movement from your brain to your muscles
Somatic nervous system
involuntary and unconscious actions (breathing, blood pumping, etc)
autonomic nervous system
Part of the autonomic nervous system activated during the “fight or flight”response to stress
sympathetic nervous system
part of the autonomic nervous system activated during the “rest and digest” response to non-stressful situations
Parasympathetic nervous system
An automatic involuntary response to a particular response
reflex
Part of the neuron that receives messages
Dendrites
Part of the neuron that keeps the neuron functional
Soma
part of the neuron that protect nerve and speeds up messages
Myelin Sheath
Part of the neuron that carries messages
axon
part of the neuron that sends signals
axon terminals
action potential “firing”
Neuron sends information
resting potential
Neuron is charged and ready to fire
All or none principle
neuron fires at full strength or not at all
Chemical messengers
Neuro transmitters
cause neurons to fire (more action potential)
Excitatory neurotransmitters
prevent neurons from firing (less action potentials)
Inhibitory neurotransmitters
Movement and memory
acetylcholine
mood
serotonin
Pleasure chemical of the brain
Dopamine
response to danger “ fight or flight”
norepinephrine
calming the central nervous system
GABA
thinking, memory, learning
Glutamate
relieve pain and stress, feelings of pleasure/euphoria
Endorphins
sensory neuron, sensory input to the spinal cord into the brain
Afferent neuron
Motor neurons carry signals away from central nervous system to initiate an action
efferent neuron
middleman between the afferent and efferent neurons
Interneuron
studied speech disorders. Region of the cerebrum responsible for speech comprehension named after him
Carl Wernicke
System of glands that secrete hormones into the bloodstream to maintain the bodies homeostasis
Endocrine system
Chemical messengers that travel through the blood stream
hormones
Endocrine organs that produce and secrete hormones
Glands
The primary gland in the endocrine system regulated by the hypothalamus
pituitary gland
produces and secretes hormones that regulate metabolism; found in the neck
Thyroid gland
produces and secretes stress hormones like cortisol and epinephrine cadrenaline
adrenal gland
Device that uses electrodes on the scalp to detect and record the brain waves
Electroencephalogram (EEG)
uses magnetic fields and ratio waves to produce high resolution images of brain structure

Adaptations
is a state of being aware of your environment and your own mental activity
Consciousness
all the things within one’s awareness at the present moment
Conscious level
Body’s automatic biological processes, like breathing and heartbeat which are controlled by brain but outside consciousness
Non-conscious level
when exposure to a stimulus beneath conscious awareness influences a response to other stimuli
priming
A period of dreamless sleep
NREM sleep
Period of sleep that is most associated with dreaming
REM sleep
another name for REM sleep, due to the contradictory way in which the brain is active but the body is at rest
