Pysch: The Brain

The wave form of a sound wave determines the

Quality

Mike lost the ability to move his left arm

Right Hemisphere

the stimulation of sensory receptors and transmission of sensory information to the CNS

Sensation

the diminishing responsiveness of our sensory systems to prolonged stimulation

Sensory Adaptation

These neurons are responsible for sending information to the brain

Sensory Neurons

The division of the peripheral nervous system that controls the body's skeletal muscles.

Somatic

Branch of the autonomic nervous system responsible for the fight or flight response

Sympathetic

Tylerand Hayden both often flew into a rage and started picking fights with eachother

Amygdala

Branch of PNS acting or occurring involuntarily without conscious control

Automatic

Cocaine and Heroin both effect our heart rate what part of the nervous system is being effected

Automatic

Subliminal Stimulation

Belowon's absolute threshold for conscious awareness

The point where the optic nerve exits the eye and where there are no photoreceptors

Blindspot

Analysisof stimulus begins with sense receptors and works up to the level ofthe brain and mind

Bottom-up

Neuroplasticity

Brains ability to reorganize and create new neural pathways

Sammy's speech was choppy, slow, and a grammatical mess.

Brocca's Area

Katie had problems coordinating her movement and keeping her balance.

Cerebellum

Our brain completes pictures that are not finished

Closure

Drug causes increased heart rate, possible hostility, and restlessness or irritability

Cocaine

size constancy is based on the close connection between an object'sperceived size and its

Distance

Doctors want to measure electrical activity in the brain when a person sleeps

EEG

Effects lead to distortion in perception, hyper-awareness of surroundings, and increased energy

Ecstasy

Lauren and Toni suffered from an impaired ability to initiate, plan, and make good judgments

Frontal Lobe

alcohol effects reasoning, decision making, and memory what parts of the brain are inhibited

Frontal Lobe and Hippocampus

Danielle suffered from an inability to form new memories.

Hippocampus

Jeremyand Drew seemed to always be hungry and their temperatures ran high

Hypothalamus

Zak and Kyle were uncontrollably thirsty

Hypothalamus

Cocaine causes an increase in body temperature what part of your brain is effected

Hypothalumus

Drug causes state of excitement, increased pulse rate, insomnia, and distorted perceptions

LSD

Paul experienced difficulty with analytic thinking, science, and math reasoning

Left Hemisphere

Doctors are looking to see if there's a tumor on Tom's Pituitary Gland Tom must avoid radiation

MRI

Drug inhibits learning and memory, basic bodily functions, and thinking and emotion

Marijuana

Amanda experienced irregularities in heartbeat and respiration rates

Medulla

These Neurons are responsible for sending information from your brain to the rest of your body.

Motor Neurons

Kelsey's eyes seemed fine, but she still had lost her vision in her left eye.

Occipital Lobe

cells increase firing rate to signal one color anddecrease firing rate to signal opposing color

Opponent Process Theory

Natalie could no longer respond to her doctor's soft tap on the knee.

Parietal Lobe

when sensations are organized, interpreted, and formed into innerrepresentations of the world

Perception

The frequency of a sound wave determines the

Pitch

Mackenzie started growing much, much larger.

Pituitary Gland

Sara often kept falling asleep at odd times and in odd places.

Pons

This processingrefers to how our knowledge and expectations influence perception

Top-down

The process by which sensory information is converted into a neural impulse

Transduction

Damage to this area does not affect ability to speak but rather the understanding and content

Wernicke

Thetendency to organize stimuli into smooth, uninterrupted patterns is called

contitnuity

Weber's Law states that

difference Threshold for a stimulus is a constant proportion

Doctors want to see if the structural damage and activity levels of the brain coinside

fMRI

reason you're able to detect fine details when scenesare focused on the fovea of your retina is

high concentration of cones

Phenomenon that refers to the ways in which an individual's expectationsinfluence perception is

perceptual set

In the opponent-process theory, the three pairs of processes are

red-green, blue-yellow, black-white
