YouTube: Curious Case of Phineas Gage
Phineas P. Gage (1823-1860) American railroad construction
worker.
★ He is remembered for his improbable survival of an
accident in which a large iron rod was driven completely
through his head.
★ Much of his left frontal lobe was destroyed.
★ The reported effects were personality & behaviorally
based.
★ Over the succeeding 12 years - effects so profound that for a
time (at least) his friends reported that they say him as, “No
longer Gage.”
The Curious Case of Phineas
Gage
★ Personality comes from the brain, not
heart.
★ We can operate on the brain and people
could survive.
★ Very famous example in medical &
psychological research.

Biological Bases of Behavior - Things to Know
1. The different methods for peering into the human brain
2. What the areas of the brain control
3. The structure of the neuron
4. The action potential
5. The role of neurotransmitters in neural transmission
Biological Bases of Behavior - Quick overview of what we’ll
learn:
Nervous System: The Basics
Neurons – Individual cells in the nervous system that receive, integrate, and
transmit information.
They are basic links that allow communication within the Nervous System.
Soma – Cell Body of the neuron that contains the nucleus and much of cells normal
organs.
Dendrite – Parts of a Neuron that receives information.
Axon – Long fiber that transmits information away to other neurons, muscles, or
glands.
Myelin Sheath – Insulating Material that encases some Axons.
Biological Bases of Behavior - Quick overview of what we’ll
learn:
Organization of Nervous System Peripheral Nervous System & Central Nervous System
Nerves – Bundles of Neuron Fibers (Axons) that are routed together in the Peripheral
Nervous System.
Peripheral Nervous System – Made up of all those nerves that lie outside the Brain
and Spinal Cord.
Somatic Nervous System – Made up of Nerves that connect to voluntary skeletal
Muscles and to Sensory Receptors.

Looking Inside the Brain: Research methods
Electrical Recording – Electroencephalograph (EEG) - Device that monitors the
electrical activity of the Brain over time by attaching Electrodes t the scalp.
Lesioning – Destroying pieces of the Brain and observing the effects. Mostly done on
Animals.
Electrical Stimulation of the Brain (ESB) – Sending a weak electric current into a
brain structure to stimulate (activate) it.
Transcranial Magnetic Stimulation (TMS) – Technique using Magnets that permits
scientists to temporarily enhance or depress activity in a specific area of the Brain.
Brain-Imaging Procedures – CT. PET, and MRI scans can give scientists imaging of
the Brain and the parts of it that are aroused by stimuli.

Endocrine System
★ Endocrine System – Consists of Glands that secrete chemicals into the
bloodstream that help control bodily functioning.
★ Hormones – The chemical Messengers in the Endocrine System.
○ Hormones travel throughout the body much slower than Neurotransmitters.
○ They regulate many physical and Behavioral functions.
★ Pituitary Gland – Based in the Hypothalamus, it releases the Hormones into the
body.
★ The Endocrine System is in charge of the Adrenaline effect.

learn:
Heredity and Behavior
Behavioral Genetics – Field that studies the influence of
Genetic Factors on Behavioral Traits.
Basic Principles of Genetics
Chromosomes – Strands of DNA that carry Genetic
Information.
Zygote – Single Cell formed by the union of a Sperm and Egg.
Genes – DNA segments that serve as key units in Hereditary
Transmission.
