Nuerotransmitter serotonin affects |
Mood, hunger, sleep, and arousal |
|
Dopamine influences |
Movement, learning, attention, and emotion |
|
Endorphins |
Naturally ocurrinf opiate-like nuerotransmitterd in the brain |
|
Heroin and morphine can |
Stop the production of endorphins |
|
Nervous system |
The neurons of the body |
|
Central nervous system |
Brain and spinal cord comprimise this |
|
Sensory and motor axons are bundled into electrical cables called |
Nerves |
|
Somatic nervous system |
The division of the peripheral nervous system that enables voluntary control of the skeletal muscles |
|
What controls the responses of the glands and muscles of interal organs |
Automonic nervous system |
|
Homeostasis |
The process where the sympathetic and parasympathetic steady our internal state |
|
Neural networks |
When your brain clusters into work groups |
|
Bodys chemical communication network |
Endocrine system |
|
What does the endocrine system do |
Transmits info thru chemical messengers called hormones at a much slower rate than the nervous system. Effects last longer |
|
Pituitary gland |
Control center |
|
Hypothalumus |
Helps regulate growth and promotes social interactions through the release of oxytocin |
|
The feedback system linking the nervous and endocrine systems is thus: |
Brains hypothalamus-pituitary-other glands-hormones-body and brain |
|
EEG |
Recording of the electrical activity of the whole brain |
|
PET Scan |
Depicting level of activiry of brain areas with glucose |
|
MRI |
Magnetic fields and radio waves to produce clearer images of the brain |
|
Functional MRI |
Detects blood rushing to the part of the cortex thought to control the bodily activity being studied |
|
Brainstem |
The oldest and intermost region of the brain |
|
Medulla |
Base of the brainstem Controls breathing and heartbeat |
|
Pons |
Above brainstem Helps cordinate movement |
|
Thalamus |
Top of the brainstem Sensory control center Recievws info from all senses excepr smell |
|
Reticular formation |
Nerve network inside the brainstem that plays an important roll in controlling arousal |
|
Cerebellum |
Rear of the brainstem Process and stores memories Judge time Discriminate sounds and textures Control emotion CORDINATION OF VOLUNTARY MOVEMENT AND BALANCE CONTROL |
|
Limbic system |
Located between the brainstem ans cerebral hemisphere |
|
Hippocampus |
Component od limbic system Processes conscious memory |
|
Amygdala |
Agression or feae will stimuate thisa |
|
4 lobes of the brain |
Frontal, parietal, occipital, temporal |
