Naturalistic Observation

Study observing behaviors in natural environment w/out intervention

Case Study

intense and in detail study of one specific person

Correlation

study of relations btwn two or more variables

Experiment

Manipulating independent variable to see effect on dependent variable

Plasticity

Ability to adapt to new environment conditions

All or none law



either a neuron fires or it does not

Seretonin

A neurotransmitter that affects mood, sleep, dreaming, eating, pain, etc. ( low levels: Depression)

Dopamine

Neurotransmitter that affects voluntary movement, learning, emotion& memory (low: parkinsons) (high: schizophrenia)

Ach( Acetycholine)

neurotransmitter that has a role in arousal, attention, memory and movement (low: paralysis) (high: spasms)

Endorphins

Neurotransmitter that inhibits pain

Motor (Efferent)

Brain to muscle

Sensory (afferent)

External stimuli message to the brain

Interneuron (Association)

from one neuron to another neuron

CNS

Brain& Spinal cord; 90% of our neurons

PNS

Nerves from rest of the body that bring messages to CNS

Somatic NS

part of PNS; transmits movement& environment info via senses; voluntary

Autonomic NS

part of PNS; transmit info to&from internal stuff; involuntary

Sympathetic ANS

excited during stress

Para-Sympathetic ANS

relaxes after stress

Medulla

controls breating, BP & HR

Pons

produces sleep/wake cycles

Cerebellum

little brain; balance/coord, emotion control, attn, memory, and organizing sensory info

Thalamus

Relay station; sensory is brought to higher functions of brain

Hypothalamus

motivation& body temp; related to rage,terrory& pleasure

Reticular Formation

network of neurons; off during sleep

Hippocampus

associated w/ new names, faces, events

Amygdala

Brocas Area

speech production

Wernickes Area

Language Comprehension

Sensation

Our experience of sensory stimulation from any sense

Perception

process of brain organizing that raw sensory into meaninful patterns

Sense Receptor

Specialized cells respond to only 1 type of energy, convert that energy to neural impulse & send to brain

Cornea



class casing of eye

pupil

opening where light enters eye

Iris

colored part of eye

Lens

Focuses light onto retina

Retina

lining of eye sensitive to light

Fovea Cavitiis

Center of visual field

Waking Conciousness

All thoughts, feeling and perceptions which occur when we are awake and alert

Altered states of conciousness

Detached in varying degrees from our enviroment

Sensory Adaptation

Large amounts of stimuli: Senses less sensitive; Small amounts of stimuli: senses more sensitive

Transduction

The conversionof physical energy into coded neural signals

Daydreaming

About evry 90 mins; peaks 12 pm-2 pm; normal momentary escape for stress relief
