Chapter 2 Flashcards
Sections of the brain
forebrain, midbrain and hindbrain
the function of the forebrain
receive and process sensory info
higher-order thinking processes
the function of the midbrain
coordination of movement
sleep
arousal
the function of the hindbrain
spinal cord brain link (movement and balance
the upper section of the spinal cord -
communicates between upper body parts and the brain
the lower section of the spinal cord -
communicates between the lower body and the brain
The Central Nervous System consists of -
brain and spinal cord
The Peripheral Nervous System consists of -
somatic and autonomic nervous systems
the Somatic NS - by -
controls voluntary movement -
motor neurons send messages from CNS to muscles causing movement
the Autonomic NS - such as -
sends info between CNS and non-skeletal muscles
the heart, all organs and glands
The sympathetic nervous system controls the -
fight : flight : freeze survival response
The parasympathetic nervous system brings about
homeostasis
How many lobes of the brain are there?
four
the function of the parietal lobe
visual-spatial perception and orientation
3D shapes and design
the parietal lobe includes the primary somatosensory cortex, what is its function
processes sensation
such as touch, pressure, temperature and pain.
the function of the occipital lobe
vision
the function of the temporal lobe
primary auditory information
comprehension of human speech, listening to music
the function of the frontal lobe
speech
abstract thought
planning
social skills
the function of Broca’s area
coordinates oral movement and vocal cords
use and understand grammar
what is the condition called if Broca’s area is damaged and what are the side effects
Broca’s Aphasia
difficulty putting sentences together despite understanding language
The functions of Geschwinds Territory
process word properties such as how they sound, what they look like and how they’re used
Interpret and classify things
necessary for abstract thought
The function of Wernicke’s area
receptive language
language comprehension
what system are conscious responses controlled by -
Somatic Nervous system
What role does the PNS have in conscious and unconscious responses
maintains homeostasis
Types of unconscious responses and examples
Unconscious - autonomic blinking Unconscious - spinal reflexes monosynaptic reflex arc- knee jerk polysynaptic reflex arc - hand withdrawal from pain
Sections in the limbic system
amygdala
hypothalamus
hippocampus
the function of the amygdala
activates and process emotion
memory recollection and storage
condition
the function of the hypothalamus
basic survival actions
physiological response to emotional stimuli
the function of the hippocampus
regulation and expression of emotion
recollection of info to relevant situations
Le Doux’s Theory Short Route
Emotional stimulus -> Thalamus ->Amygdala -> Emotional response
Le Doux’s Theory Long Route
Emotional stimulus -> Thalamus -> Sensory Cortex -> Amygdala (or Hippocampus -> Amydgala) -> Emotional response
