The receiver of the neuron
Dendrite
The golden ratio is
1:1.618
What is State of Awareness
What is an extrinsic Award
An award that comes from an external source
Classical Conditioning is what type of learnings
Associative learning
What area of the brain is the last to be myelinated and what can it lead to.
The Frontal cortex (specfically pre-frontal) is the last to be myelinated and can result in impulsive decision and irrational thinking.
The pupil is
the opening in the iris
Alpha and Beta is recorded by the EEG in what stage of the wakefulness/sleep cycle
Wakefulness
What is Leptin
A hormone that is released to maintain the appropriate level of stored fat.
List the three main types of learning.
Associative, Nonassociative and Observational
What does the neurotransmitter Glutamate do
Created Excitation in brain activity
90% of axons synapse in the:
Thalamus
What is Narcolepsy
In which a person will endure "sleep attacks". this is when REM sleep occurs during the wakefulness stage. Attacks can be results of strong emotions
Define the Schafter-Singer two factor theory
General arousal, not specific physical states, leads to an appraisal of our surroundings, which allows us to identify our subjective feelings.
What is the Classical Conditioning phenomenon
CS predicts the nonoccurrence of the UCS
What is the function of Magnetoencephalography (MEG)
A neuroimaging technique used to record the tiny amounts of the magnetic output of the brain
Where does the perception of pitch occur first in
Opiates tend to act on the:
Endogenous Endorphins
What is a display rule:
A cultural norm that specifies when, where, and how a person should express an emotion.
What is the Token economy
An application of operant conditioning in which tokens that can be exchanged for other reinforcers are used to increase the frequency of desirable behaviors.
Define what a hyperpolarized and depolarized neuron is.
Neurons can respond to incoming signals by becoming hyperpolarized or depolarized. Depolarization and Hyperpolarization are the measures of the difference between the electrical charges in the extra and intercellular
What is the Gate Theory
According to the thoery, touch fibres compete with input from pain receptors. The touch fibers dilute the amount of pain information reaching the brain
Hypnosis is:
A way of deliberately influencing consciousness
In our brains, there are no "happy centers" or "sad centers". wherein our brains do we perceive emotion and how.
Emotion is perceived through the cerebral cortex and through reoccurring patterns.
What is latent learning
latent learning Learning that occurs in the absence of reinforcement.
