Sensory

Interneuron

Input from sensory organs to brain & spinal cord

Output from the brain & spinal cord to muscles & glands

Carry info. Between other neurons (only found in brain and spinal cord)

Functions Surplus DeficitDopamine Influence: Movement, Learning, Attention, and Emotion Parkinson's Disease Depression

Serotonin Affects: Mood Hunger, Sleep, and Arousal Sleepy Violence, Depression, and Anxiety

Norepinephrin Helps control: Alertness and Arousal Happiness Depression

GABA Inhibitory Neurotransmitter Relaxation, loopyness Seizures, Insomnia, and Anxiety

Glutamate Memory Injures brain cells Causing MS

Acetylcholine(ACh)Muscle Contraction paralysis, Convulsions, or Death Memory impairment Alzheimer’s

Endorphins Released in response to: Pain and Exercise “Runner’s High” Happiness Emotional, Crying,Chronic pain

Central nervous system(CNS) – Brain and Spinal cord

Peripheral nervous system(PNS) – links CNS with body’s sense receptors, muscles and glands

Left: Language Right: Math &Music

Back of head, Optic nerve SIGHT

Sides of head above ears, Auditory cortex HEARING –speech, facial, word recognition & memory formation

Back top of head, hand-eye coordination,

Front of head, working memory, motor cortex

Brainstem: where spinal cord swells as it enters skullMedulla: base of brain stem, heartbeat & breathingReticular Formation: between ears spinal cord to thalamus, arousalThalamus: top of brainstem, sensory switchboard- not smellCerebellum: back of brain, voluntary movement & balance

Amygdala- almond shaped, aggression & fear Hypothalamus - bellow thalamus, eating drinking body temp. reward centersPituitary gland – pea sized base of brain, controls endocrine system

Hormones – chemical messengers, produced in one tissue and effect anotherAdrenal Gland – above kidneys, release epinephrine & norepinephrine is stressful situationsPituitary gland – pea sized base of brain, controls endocrine system
