1.1 Nature v. Nurture
Refers to the genetic or hereditary influences on human traits and behaviors.
What is Nature?
Includes the brain and the spinal cord, and is the body's processing center.
What is the central nervous system?
the neuron extension that passes messages through its branches to other neurons or to muscles or glands.
What is the axon?
The 24 hour sleep and wake cycle in your body
What is the circadian rhythm?
Describes the degree to which stimuli need to be different for the difference to be detected.
What is Weber's Law?
Nature selects traits that best enable an organism to survive and reproduce in a particular environment
What is natural selections?
The nervous system that includes the somatic and autonomic nervous system
What is the peripheral nervous system?
Neurotransmitters not absorbed by the receiving neurons, drift away are broken down by enzymes or are reabsorbed by the sending neuron
What is repuptake?
Part of the brain that impacts balance and procedural memory
What is the cerebellum?
Light sensitive inner surface of the eye containing receptor rods and cones
What is the retina?
What are identical twins?
The nervous system responsible for the "Fight or Flight" response
What is the sympathetic nervous system?
AKA "Glue Cells" send and receive chemical signals to and from each other and to and from the neurons.
What is glial cells?
Part of the brain that is severed in a split-brain procedure
What is the corpus callosum?
The process of external stimuli becoming perceptions, thoughts, and emotions
What is transduction?
The study of environmental factors that can cause changes to gene activity without altering the DNA sequence
What is epigenetics?
Heart rate, blood pressure, breathing and digestion are all functions in this system.
What is the autonomic nervous system?
This neurotransmitter enables all of your muscle movements and a decrease is associated with Alzheimer's and dementia.
What is Acetylcholine (ACh)?
The hemisphere that has the ability to recognize faces
What is the right hemisphere?
The thousands of bumps on the tongue that include the taste buds.
What is papilla?
Intelligence is an example of the variation among individuals that we can attribute to genetics.
What is heritability?
Communicates sensory information to the central nervous system
What is the somatic sensory neurons?
A type of drug that leads to no activation and inhibits the actions of neurotransmitters. Thorazine limits how much dopamine enters the synapse.
What is a antagonist?
Part of the left hemisphere that is involved in expressive speech.
What is Broca's Area?
The brain knows that if certain cilia are stimulated, it should interpret that as different pitch.
What is Place Theory
