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
