Nervous System1.2

nervous system1.2
central nervous system1.2.A.1 interacts with all processes in the body.
brain 1.4
brain stem (including the medulla)1.4.A.1 controls basic functioning such as breathing and heart rate.
reticular activating system and the brain’s reward center1.4.A.2 control alertness, some voluntary movement, eye movement, and some types of learning, cognition, and emotion
cerebellum1.4.A.3 controls coordination of muscle movement, balance, and some forms of procedural learning
cerebral cortex1.4.A.4
is divided into two hemispheres1.4.A.5 Split brain research, achieved by severing the corpus callosum (often a treatment for severe epilepsy), reveals that the right and left hemispheres of the brain may specialize in different activities and functions.
left hemisphere1.4.A.5.i Areas of the brain that affect language
Broca’s area responsible for speech production
Wernicke’s area responsible for speech comprehension
right hemisphere spatial reasoning, facial recognition, emotional tone of speech, understanding metaphor/sarcasm
and includes the
limbic system
thalamus directs sensory input from the peripheral nervous system to the various parts of the brain for processing
hypothalamus regulates hunger, thirst, body temperature, sex drive; controls pituitary gland (master gland of endocrine system)
pituitary gland secretes hormones into the bloodstream, where they circulate throughout the body and induce changes in cellular activity
hippocampus responsible for processing new memories
amygdala regulates emotional reactions
corpus callosum Connects the two hemispheres; severing it (split-brain procedure) treats severe epilepsy and reveals hemispheric specialization
lobes of the cortex
occipital lobes1.4.A.4.i generally control visual information processing and are located in the rear of the brain.
temporal lobes1.4.A.4.ii control auditory and linguistic processing and are located on the sides of the brain.
parietal lobes1.4.A.4.iii are located near the back crown of the brain. generally control
association areas process and organize information
somatosensory cortex processes touch sensitivity
frontal lobes1.4.A.4.iv located just behind the forehead
prefrontal cortex control linguistic processing, higher-order thinking, and executive functioning
motor cortex is located at the rear of the frontal lobes and controls most types of skeletal movement.
spinal cord reflexes, signal highway
peripheral nervous system1.2.A.2 relays messages from the central nervous system to the rest of the body
autonomic nervous system1.2.A.2.i governs processes that are involuntary
sympathetic nervous system arouses the body and readies it for action (fight-or-flight)
parasympathetic nervous system helps calm the body and instigates digestion of food (rest-and-digest)
somatic nervous system1.2.A.2.ii governs processes that are voluntary.

Other things about the brain 1.4

test for cortex specialization1.4.A.5.ii Researchers test for cortex specialization with split-brain patients by showing information in each visual field, taking advantage of the brain’s contralateral hemispheric organization.
Brain plasticity1.4.A.6 the ability of the brain to rewire itself or modify or create new connections throughout development and generally allows for the function of a damaged part of the brain to be assumed by a different part of the brain.
Research on the brain is done...1.4.A.7 to promote understanding of how the different structures of the brain work and how the brain functions together as a whole using
scans
EEG measures brain wave activity generally in the brain
fMRI measures brain activity in specific parts of the brain
case studiesI LOVE NICE
surgical procedures such as lesioning, a surgical technique that removes parts of the brain to treat psychological or physical illnesses.
