Action potentials occur either at a uniform and maximum intensity, or they do not occur at all
What is the All-or-None Law?

The neural bridge that acts as a major communication link between the two hemispheres and allows them to function as a single unit.
What is the corpus callosum?

In an experiment, this is the outcome variable that is measured.
What is dependent variable?
200
The ability to repeat the experiment and get the same results.
What is reliability?
200
Changes in the negative resting potential that do not reach the action potential threshold.
What are graded potentials?

This procedure allows us to look at both function and structure of the brain.
What is an FMRI?

A __________ is said to have occured when participants' expectations lead them to experience some change even though they receive empty, fake, or ineffectual treatment.
What is the placebo effect?
300
During this stage, a portion of the membrane becomes permeable to positively charged ions. Then, positively charged ions rush inside reversing the neuron’s electrical potential.
What is depolarization?
300
The relatively greater localization of a function in one hemisphere or the other.
What is hemispheric lateralization?
300
When we are perceiving something due primarily to from information in the external world, we are using this kind of processing.
What is bottom-up processing?

The chapters that will be covered on the exam.
What are chapter 1, 2, 4, and 5?
400
The extent to which an experiment measures what it is trying to measure.
What is validity?
400
Neurotransmitters bind to neurons at post-synaptic ___________.
What are receptor sites?
400
This method for examining the brain measures the activity of large groups of neurons through a series of large electrodes placed on the scalp.
What is an EEG?
400
The smallest difference between two stimuli that people can perceive 50% of the time.
What is the JND?
400
The idea that our experience is not always reality. (hint: I think, therefore I am).
What is rationalism?
500
The independent variable in the bystander effect studies.
What is the amount of people present?
500
A neuron's natural electric charge.
What is resting potential?

Why can split-brain patients identify objects/faces in their right visual field, but cannot name them?
Localization of language functions are in the left hemisphere.

According to this theory, cones are most sensitive to wavelengths corresponding to blue, green, and red.
What is the trichromatic theory?
500
By doing this, Dr. Murnane was able to better see cats in the dark.
What is not looking directly at the cat? We want to use the rods, not cones, so look to the SIDE of where you think the object that you want to see might be!
