1. Leo Kanner is associated with autism.
2. Confabulation: fabricate imaginary experiences as compensation for loss of memory
3. Coup: contact of the brain with the skull at the point of trauma 4. Concussion: temporary halt in brain function as a result of a blow to the head.
5. left hemisphere is dominant because it has languages: cerebral dominance
6. fluoxetine: SSRI used to treat depression (i.e. Prozac, Zoloft, Paxil) 7. Rett’s disorder: Autism Spectrum Disorder…only in girls, mental retardation, hand-wringing, 2-3yrs, genetic disorder, sex linked 23 chromosome
8.blood brain barrier: separation of circulating blood from the brain extracellular fluid in the central nervous system; acts as a gatekeeper for the brain blocking harmful substances from entering while allowing necessary nutrients.
9. neurological diseases are hard to cure because of the blood brain barrier which treats medications as the enemy preventing the therapeutic agents from doing their job.
10. Phobia: irrational fears
11. the primary visual center is located in the occipital lobe Brodmann area 17
12. list three basal ganglia structures:
13. Prosopagnosia: inability to recognize faces and causes damage in the fusiform gyrus.
14. cerebral asymmetry: each hemisphere specializes in a particular function; the left hemisphere has the function of language while the right holds the functions of music and creativity
15. transient ischemic attack: blood flow to the brain stops for a brief period of time
16. The basic malfunction causing Down’s syndrome is chromosome 21 has three chromosomes instead of 2
17. the nervous system defect in multiple sclerosis: demyelination of axons; damage to the myelin sheath
18. inside the body codeine turns into: morphine
19. the role of dopamine in schizophrenia acts as a anti-psychotic; works as a dopamine antagonist/blocker
20. astrocytes are star shaped glial cells located in the central nervous system. One of it’s functions is the provision of nutrients to the nervous tissue
21. the basic neurotransmitter dysfunction is Parkinsonism is : lack of dopamine
22. oxytocin and vasopressin originated from hypothalamic cells; they are two hormones of the posterior pituitary
23.three stages of Tourette syndrome:
1. Multiple tics or bleaks
2. Little cries or shouts
3. Shouting of words a) Echolalia , b) Corprolalia
25. Two Subcortical dementias:
• 1. Huntington’s Chorea
• 2. Parkinson’s Disease
26. the central nervous system consists of the: brain and spinal cord 27. name of fluid in the ventricles of the brain: cerebrospinal fluid 28. Tract: a bundle of axons found in the central nervous system 29. Alexia: inability to see words or to read
30. REM characteristics: occurs in the transition stage of 1 and 2 it’s the only time you dream.
• Brain wave scan or EEG show low amplitude
• Theta waves
• Smaller and irregular waves
• Blood pressure increases
31. Capgras syndrome: the delusion that individuals in your immediate surroundings have been replaced by doppelgangers
32. coma: state of unconsciousness
33. Autism Spectrum Disorders:
• 1. Autism
• 2. Asperger’s syndrome
• 3. Pervasive Developmental Disorders-Not otherwise specified (PDD-NOS)
• 4. Childhood Disintegrative Disorder
• 5. Rett’s Disorders
34. Vascular defect in Williams syndrome: aortic stenosis
35. Oxygenated blood from the lungs is returned to: the left atrium 36. Narcolepsy: Daytime REM sleep
37. Psychosomatic medicine: an interdisciplinary medical field studying the relationships of social, psychological, and behavioral factors on bodily processes.
38. Bell-Magendie law: anterior spinal roots contain only motor fibers while the posterior roots contain only sensory fibers.
39. The nervous system originates from the: ectoderm
40. Parts of a neuron:
• Cell body
