What is a neuron?
The individual cell that acts as an information processor for the nervous system.
What was significant about Phineas Gage?
A three foot iron rod was shot through his cheek and into his frontal lobe --> a good example of a clinical case that let scientists learn about the workings of the frontal lobe.
Transcranial Magnetic Stimulation
creates strong magnetic pulses on the scalp that temporarily disrupts brain function.
CT scan
A series of X rays that are used to construct a composite image of the brain.
Magnetic Resonance Imaging
Use a high frequency alternating magnetic fields throughout the brain. Magnetic sensors detect the reverbrations and identify which brain tissue the vibrations came from, constructing a picture.
Reveals brain function
detects tiny electrical currents on the surface of the brain
Positron Emission Tomography (PET Scan)
Patient is injected with a dose of radioactive substance that has a similar structure as glucose (the only sugar the brain uses), so when a certain area of brain is stimulated by senses, the radioactive isotope is detected.
Detects changes in blood flow and oxygen in the brain to determine which parts are the most active at any moment.
What are two ways that the nervous systems differ from each other?
In centralization and in size
relay messages from the sense organs to the muscles
hind brain


hindbrain- closest to the tail
forebrain-closest to the head

midbrain- in the middle
-regulates the cardiovascular and respiratory systems
-controls reflexes like swallowing
-helps us maintain balance
integrates movements of the face ears and tongue
hangs behind the pons and controlls overall bodily balance
- learning movement/motor skils
midbrain controls:
body temperature/pain perception
- targeting sound

longitudinal fissure
where is the thalamus located and what does it do?
-sits atop the midbrain

- acts as a relay station for sensory info going to the cortex
-lays under the thalamus

- controls motivated behavior like feeding drinking and sexual activity
basal ganglia
-lie astride the thalamus

-regulate muscle contraction (parkinson's disease)
limbic system
-surrounding the thalamus and basal ganglia lying below the cortex

- includes amygdala and hippocampus
affrent nerves
transmit infromation from organs to brain
effrent nerves
transmit info from CNS to muscles and glands that are the organs of actions
Primary Projection Areas
Areas in the brain that roughly correspond to parts of the body that they represent or influence
Wilder Penfield
created a map that showed which parts of the primary motor cortex controlled which parts of the body.
somatosensory area
located in the parietal lobe behind the primary motor projection area, it receives sensory info from the skin
nonprimary projection areas
organize and relate the various messages that come from the sensory projection areas or go to the primary motor projection areas.
-(disorder of action)
disturbances in the initiation or organizaion of voluntary action
- ie being asked to light a cigarette and putting the lit match in his mouth; problems in initiating the sequence or getting the components to fit together
(disorder or perception)

-sufferers cannot identify familiar objects using sight (the damage is in the occipital lobe). They can recognize a car key by holding it but not by looking at it.

-rarely not just confined to faces, sometimes a person who could identify lots of -different types of cars cannot etc.
neglect syndrome
'forget' left side of tasks
disorder of language
nonfluent aphasia
-a disorder that involves the production of speech (understand words, but cannot speak)

-lesions in the posterior region of the frontal lobe in Broca's area
fluent aphasia
-patients can produce a 'word salad', but do not understand what is said to them.

-lesions are posterior part of temporal lobe in the Wernicke area
disorder of the prefrontal area
-such was the case with Phineas Gage, the front most part of the frontal lobe was severly damaged, leading to marked changes in personality.
-patients are unable to use rules
prefrontal lobotomy
-Edgar Moniz Leukotomy
-in the 1940's and 50's an icepick would be inserted through the eye and sever the connection between the thalamus and the frontal lobe
left hemisphere controls

right hemisphere
-spatial cognition
-the most massive portion of the brain
-it size gives us flexibility in behavior
Describe HM's case study
-clonic seizure disorder
-sugeons resected medial temporal lobe and distroyed his hippocampus

Anterograde Amnesia
Cannot lay down new memories

-Aliens spoke through her
Even after a belief is disproved, people believe it even more strongly
cognitive dissonance
Strengths and weaknesses of Observation
Strengths: people act normally
Weaknesses: 1. potential bias of observers
2. cannot determine cause and effect
Objective Test
Try to be as impartial as possible. Performance based objective tests are the MCAT and SAT
Projective Tests
- look for patterns
- measures a skill or ability outside of conscious awareness.
Strengths and weaknesses of tests
-easy to administer
-measures beliefs, attitudes and feelings

difficult to develop and subjective scoring
Correlational studies
show how two phenomenon are related
allows for preliminary predictions
weakness of correlational studies
often times cannot untangle cause and effect. (latin in highschool-->better grades in college)
Strengths of experiments
identifies cause and effect
weakensses of experiments
situation is artifical and not always generalizable.
Explain what a control group is in terms of the candy experiment
The group that doesn't get the candy
What is the independant variable in the candy experiment?
The thing that we manipulate -Candy
What is the dependant variable in the candy experiment?
Memory- the thing that depends on the candy (independant variable)
Randomness in terms of candy expt.
People should be randomly selected, not all candy lovers should be in the same group.
Representitiveness (in terms of candy expt)
Group needs to reflect the general population
Random sampling
lottery, like with a jury
Stratified sampling
when the sample must accurately reflect the demographics of the larger population.
All members of a given group (all three year old boys, all autistic children)
a subset of the population they are interested in.
matching (candy expt)
identifying one variable the might be linked to the dependant variable (memory). For example, gender. Therefore we put one woman and one man in both the control and experimental group.
