A Prezi by Daniel Kim, Hanna Park, Stephen Tan, Judith Yan
“The human brain must continue to frame the problems for the electronic machine to solve.”
- David Sarnof
Through the Brain
Has to do with:
Language & learning
Impaired by: alcohol "drunk test"
Regulates: life support operation
ex. endocrine system, hunger, thirst, body temp., motivation, sex, emotion, aggression, etc.
Associates short term & explicit memory
Left side: verbal
Right side: visual
Neural clusters; in temporal region
Linked to emotion
Examples when damaged:
Face expression recognition
Over-activity = oversensitivity
At the back of brain
Contains the visual cortex
receives input from opposite auditory fields
Processes meaning of speech and images
What do we see?
Comprehension of speech
(in contrast with Broca's)
*Disorder: Wernicke's Aphasia
Part of the brain stem
Receives/ passes on afferent messages to cerebellum and medulla
EXAMPLE: Side effects
emotion, behavior, motivation, long term memory, olfactory senses
CENTRAL NEROUS SYSTEM
neuron and its synapses
can strengthen the connections through continuous use
receives sensory neurons
activates motor neuron
EX) knee jerk, candle
above the brain stem
Giuseppe Moruzzi & Horace Magoun
stimulation in the cat’s reticular formation
Spinal Cord (2)
-Located right behind our forehead
functions speech, information processing, muscle movement, and making plans and judgement.
controls auditory, visual, motor systems
substantia nigra & red nucleus
dopamine producing area
controls heartbeat and breathing
Motor cortex & Sensory Cortex
Short and long term decision making
PERIPHERAL NERVOUS SYSTEM
Autonomic Nervous System
controls internal organs' muscles
spends energy in stressful situations
Somatic Nervous System
controls the body’s skeletal muscles
Motor & Sensory cortex
Spinal Cord (1)
-Region of frontal lobe that deals with speech production.
-Damage to this region can cause Broca Aphasia.
Perceiving and processing somatosensory events:
Integrates motor and sensory functions
