consciousness Flashcards
awareness of oneself and ones environment
consciousness
aware of your environment, maximize safety
sensory awareness
being aware of things inside yourself, instinct v choice
direct inner awareness
aware of ourselves and our existence, meaning and complexity
sense of self
activates when not performing a task, mind wandering, day dreaming
default mode network
switching between the default mode network and central executive network
salience network
engages your conscious brain to think and maintain attention on a task
central executive network
info not in the conscious but can retrieved
preconscious
memories, wishes we are unaware
unconscious
mental process that goes on in which the individual is unaware
nonconscious
people become deeply relaxed and highly suggestible to changes in behavior
hypnosis
process of learning to control bodily states with the help of machines monitoring the states to be controlled
biofeedback
the focusing of attention to clear ones mind and produce relaxation
meditation
advantages of meditation:
-increased theta wave activity
-positive emotions in prefrontal cortex
-increased feelings of bliss\
-increased cortical thickness and gray matter
all neurons
white matter
number of connections that neurons have, better problem solvers
gray matter
biological clock, 24-25 hour cycle
circadian rhythm
stage 1 NREM
falling asleep, 15-20 min light sleep, THETA WAVES
stage 2-3 NREM
breathing and heart rate slows, hardest stage to wake up, DELTA WAVES AND NIGHT TERRORS
stage 4 REM
high frequency brain waves, increased pulse and breathing, DREAMS, paralysis of large muscles (pons)
what hormone is released while we sleep?
growth hormone
sequence of images, emotions, and thoughts passing through a sleeping persons mind
dreams
dreams are our unconscious urges and wishes
psychodynamic theory (freud)
dream’s story line, who what where?
manifest content
underlining meaning of dreams, why?
latent content
REM sleep triggers neural activity that evokes random visual hallucinations that our brain weaves together stories
neural activation theory
dreams help us sort out the days events and consolidate our memories
information processing
brain stimulation from REM sleep helps develop and preserve neural pathways
physiological function
persistent problems falling asleep/staying asleep
insomnia
insomnia: general disruptions in circadian rhythm
primary
insomnia: factor affects your sleep
secondary
suffer from sleeplessness and may fall asleep at unpredictable times
narcolepsy
maintain upright, eyes open position but are still not responsive
cataplexy
wake up screaming and have no idea why
night terrors
what stage do night terrors occur?
nonREM 3
somnambulism, most often occurs during first hours or stage 3 sleep
sleep walking
wake up momentarily, gasps for air, then falls back asleep
sleep apnea
what is the treatment for sleep apnea?
CPAP
body stays in REM but mind is alert
sleep paralysis
discomfort in legs with irresistible urge to move them
restless leg syndrome
disruption to or mismatch of internal body clock
circadian rhythm disorder
