|
Reticular Activating System
Medulla Pons |
|
|
Reticular Activating System
|
Alertness and Motivation
|
|
|
Medulla
|
Blood Pressure, Heart rate, Breathing
|
|
|
Pons
|
Sleep, Dreaming (REM) Respiration
|
|
|

|
|
Thalamus
(Hearing Memory) |
Receives Sensory Information
(every sense EXCEPT for SMELL) relays this info to the parts of the brain that can make sense of it. "some schizophrenics have an abnormal Thalamus' |
|
|
Olfactory Bulb
|
Receives the sense of SMELL
sends it to the part of the brain that can make sense of it. Located near areas of the brain that deal with memory. 'Olfactory Memory" |
|
|
Limbic System
(know 3 parts) |
Hypothalamus
Amygdala Hippocampus |
|
|
Hippocampus
|
Memory
(one of the 1st area's to go in Alzheimers) |
|
|
Hypothalamus
|
Food / Water intake, Metabolism, everything autonomic.
Tells you when you are full- if not working you feel hungry all the time |
|
|
Amygdala
|
Emotions
|
|
|
Cerebral Cortex
(including the 4 lobes) |
1. Occipital Lobe
2. Parietal Lobe 3. Temporal Lobe 4. Frontal Lobe |
|
|
Occipital Lobe
|
Determines if you understand what you are looking at. "Visual Recognition"
If Damaged - visual hallucinations, problems recognizing shapes, colors etc |
|
|
Parietal Lobe
|
Spatial Skills (sense of direction, map-reading, blow-drying your hair)
Touch Sensation (hot-cold, smooth-rough) Speech Production |
|
|
Temporal Lobe
|
Understanding Auditory Stimuli
or (language) and memory for auditory stimuli. Damaged Temporal Lobe- speech problems-can't understand words. such as "Stroke Victims, Migrains" also auditory hallucinations (hear voices that are not there) |
|
|
Frontal Lobe
|
Reasoning, Planning, Motivatin, Organization, Judgement, Emotion-regulation, Personality
This area is not fully formed until adulthood (20's) although experience/responsibilities can speed development! |
|
|
Myelin
|
Fatty waxy substance that insulates portions of some neurons in the nervous system
|
|
|
Acetylcholine (ACh)
|
A Neurotransmitter related to muscle movement & perhaps consciousness, learning & memory
(Memory & Memory Loss.) |
|
|
Dopamine
|
A Neurotransmitter that plays a role in movement, learning & attention
|
|
|
GABA
Gamma Amino Butyric Acid |
A Neurotransmitter - regulates arousal & general level of energy & alterness.
* Plays an essential role in normal brain function * Loss of GABA can produce seizures, arousal levels become too high |
|
|
Wernick's Area
|
A region of the Left Temporal Lobe.
Plays a role in the comprehension of Speech (unable to understand spoken language) |
|
|
Broca's Area
|
A region of the Left Temporal Lobe.
Plays role in the production of Speech (patient unable to produce understandable speech) |
|
|
Corpus Callosum
|
A Thick Band of Neurons that connect the left & right hemisphere of the brain.
Passes information back and forth between L & R Hemispheres. (w/out it each side would ignore the other) |
