Lobes
What part of the brain are all four lobes located in?
The Cerebral Cortex
What does serotonin affect?
Affects MOOD, SLEEP, digestion, and body temperature.
What is an EEG?
Sensors attached to the scalp that record the waves of electrical activity across the brain.
Medulla
Heartbeat and breathing.
Central Nervous System
The brain and spinal cord, coordinates responses.
What does the occipital lobe do?
It interprets VISUAL information, such as color, motion, distance, and depth.
What does dopamine affect?
Affects movement, learning, attention, and EMOTION.
What's an MRI?
A high-powered magnet and radio waves are used to produce images of soft tissue and organs.
Hippocampus
MEMORY, and learning. HM had his hippocampus removed, and he became unable to form new memories.
Peripheral Nervous System
Connects the central nervous system to the limbs, organs, and skin. Enables voluntary movement and body functions like heartbeat and digestion.
What does the temporal lobe do?
It processes AUDITORY information, receiving info from the opposite ear. Also helps with comprehending language.
What does norepinephrine control?
FIGHT or FLIGHT. Controls alertness and arousal.
What is a CT scan
X ray used to create images of organs, bones, and tissues.
Cerebral Cortex
The outer layer of the brain, important for higher cognitive functions.
Somatic Nervous System

Recives sensory input for touch, pain, and BODY POSITION awareness.
What do endorphins do?
BLOCKS PAIN RECEPTORS. Activates in response to pain, stress, exercise, and pleasure.
What is a PET Scan?
Visual display of brain activity through a radioactive tracer to detect cancers, heart disease, and brain disorders.
Cerebellum
Voluntary movements, balance, and posture.
Sympathetic Nervous System
AROUSES the body.
What does the frontal lobe do?
Helps with VOLUNTARY MOVEMENT, expressive language, and HIGHER-LEVEL EXECUTIVE FUNCTIONING, such as planning, decision making, and emotions.
What does Substance P do?
Transmits pain signals.
What is an fMRI?
Reveals blood flow and brain activity, shows brain functions and structure.
Hypothalmus
Body temperature, hunger, thirst, and the sleep-wake cycle.
Parasympathetic Nervous System
CALMS the body.
