Unit 3- Myers Psychology Notes

Epigenetics

Epigenetics

________ is the study of environmental influences in gene expression that occur without a DNA change.

Interaction

________ is the interplay that occurs when the effects of 1 Factor such as environment depends on another Factor such as heredity.

Neurotransmitter systems

________ do not operate in isolation they interact effects Berry with receptions they stimulate.

Genome

________: the complete instructions for making an organism consisting of all the genetic material in that organisms chromosomes.

FMRI

________: technique for revealing blood flow and therefore brain activity by comparing successful MRI scans this also shows brain function and the Brain structure.

PET

________ scan: visual display of brain activity that detects where a radioactive form of glucose closed while the brain performs a given task.

Myelin Sheath

________: fatty tissue layer segmentally encasing the axons of some neurons-> enables greater transmission speed as neutral impulses hop from one node to the other.

opiate drugs

Some ________ are agonists and produced temporary highs by amplifying normal sensations of arousal or pleasure.

Adoptees

________ are more similar to their biological parents than their adoptive ones their environment and shared by families children's has virtually no discernible impact on their personalities.

Reuptake

________: neurotransmitter reabsorption by the missing neuron (reabsorbs excess neurotransmitters.

Synapse

________: the junction between the axon tip of the sending neuron and the dendrite /cell of the body receiving neuron-> Sir Charles Shemington (1857- 1952) noticed a neutral impulse interruption in the transmission.

Endorphins

________: morphine within natural opiate- like neutrons.

Somatosensory cortex

________: area at the front of the parietal lobes that registers and processes body tumors and movement sensation.

cerebral cortex

The ________ made up of neurons and glial cells is divided into the right and left hemispheres and into four lobes.

Corpus callosum

________: the large band of neural fibers connecting the two brain hemispheres and carrying messages between them.

Dendrites

________: neurons bushy, branching extensions that receive messages and conduct impulses toward the cell body.

Automatic

________ nervous system: part of the PNS that controls the glands and muscles of the internal organs sympathetic division arouses parasympathetic division columns.

Agonist

________: a molecule that by binding to receptor site stimulates a response this response may be similar to a new row transmission to bind to its receptors and mimic its effects.

Genes

________: the biochemical units of Heritage see that makeup chromosomes segments of DNA are capable of synthesizing proteins.

Chromosomes

________: thread- like structures made of DNA molecules entertaining the genes.

Threshold

________: The level of stimulation required to trigger an action.

Electroencephalogram

________: An amplified recording of the waves of electrical activity sweeping across the brain's surface this is measured by electrodes placed on the scalp.

Parasympathetic

________ nervous system: division of the ANS that columns the body and conserves its energy.

Axon

________: neuron extension that passes messages through its branches to the other neurons or muscles or glands.

motor cortex

The stimulation caused movement only where the ________ was located.

Hormones

________: chemical Messengers that are manufactured by the endocrine glands that travel through the bloodstream and affect other tissues.

Frontal lobe damage

________ can alter personality and remove a person's in divisions moral compass may seem unrestrained.

Neuron signals

________ can be like an accelerator or brake.

Plasticity

________; the brains ability to change Especially during childhood by reorganizing after damage or by building new Pathways based on experiences.

ACH

________ is released to muscle cell receptors therefore muscle contracts.

right hemisphere

The ________ specializes in spatial and perceptual skills, visualization, and the recognition of patterns, faces, and melodies.

Refractory period

________- a resting pause, a period of inactivity after a neuron has fried.

Harlow Face Illusion

________: conflicts with the Dual processing system of vision because the unconscious mind knows the truth of the illusion.

Consciousness

________: our awareness of ourselves and our environment this helps in the long- term interests and promotes our Survival by anticipating how we seem to others and helping us read their emotions.

left cerebral

The ________ hemisphere is primarily responsible for language and speech in most people.

nerve cells

According to biology, the body is made up of cells-> ________- that conduct electricity and communicate with the brain by sending messages across a gap that separates them.

Somatic

________ nervous system: the division of the PNS that controls the body skeletal muscles.

Behavior genetics

A goal of molecular ________ is to find some of the many genes that orchestrate traits such as body weight sexual orientation and extraverts.

Neuron

________: a nerve cell consisting of the cell body and branching fibers.

Prefrontal cortex

________: located in the forward part of frontal lobes please enable judgment planning processing at new memories.

stimulation parts

The ________ of the motor cortex in the left /right hemisphere caused movement of the opposite side of the body.

external influence

Environment: every ________ from creating natural nutrition to the people and things around us.

MRI

________: Techni using magnetic fields and radio waves to produce computer- generated images of soft tissue to show the brain's Anatomy.

occipital lobe

The ________ is primarily responsible for vision.

Cognitive neuroscience

________: the interdisciplinary study of the brain activity linked with cognition which means thinking perception memory and language.

DNA

________: A complex molecule containing the genetic info making up chromosomes.

Visual perception track

________: enables us to think about the world recognize things and plan future actions.

Neurotransmitters

________: chemical messengers that cross the synaptic gaps-> when released by sending neuro they travel across the synapse and bind receptor sites on the receiving neuron-> influence whether that neuron will generate a neural impulse.

Nerves

________: bundled axons that form neutral electrical cables connecting the CNS with muscles or glands sense organs.

Visual action track guides

________ are moment- to- moment movements.
