1

Kluver Bucy vs Temporal Lobe Epilepsy

TLE
- hyposexual
- intense fixation on ideas (viscosity)
- emotional INTENSITY

Kluver Bucy
- hypersexual
- hyperoral
- shifting attention (opposite of viscous)
- placidity

2

Episodic Memory Location

lasts seconds
Med. temporal lob
ant. thalamic nucleus
mamillary body
fornix
prefrontal cortex

3

Semantic Memory

inferolateral temporal lobes
- will allow patients to answer questions like the color of a certain breed of dog or how orange and apple are different

4

Procedural memory

Basal ganglia
cerebellum
Supplementary motor area

5

working memory

ability to store memory for several seconds while rest of brain works on it

6

REM sleep EEG waves

sawtooth, low voltage, fast activity
Also see inc HR, blood pressure and penile/clitoral erection

7

Tactile Agnosia

cannot recognize objects based on touch
- caused by damage to border of somatosensory and association areas of post. parietal lobe

8

preserved functions in frontal lobe

memory, cognition, IQ, language, praxis

9

Prader Willi

underweight infant - over weight early child
other sx include ANS dysreg, muscle weakness, hypotonic, mild to moderate MR, temper tantrum, violent outburst, perseveration, skin picking, and a tendency to be argumentative, oppositional and rigid

10

Gerstman syndrome

- parietal lobe lesion -
Agraphia
Acalculia
Right-left Disorientation
Finger Angosia

11

Apperceptive Visual Agnosia

inability to ID and draw items using visual cues w/ preservation of other senses

12

Prosopagnosia

caused by damage to inf. temporal cortices from visual assoc. area of left parietal lobe

13

Balint Syndrome

Bilateral Occipital lobe lesions
optic ataxia, oculomotor apraxia and simultanagnosia

14

psych issues seen in Fragile X

anxiety, dysthymia, antisocial p/d, OCD and ADHD

15

Ritalin OD

mimics cocaine except ALSO has hyperthermia

16

PCP intoxication

nystagmus,, drooling, vomitting,
at High doses paranoid, delusions, disorg thinking and catatonia

17

Dysfxn of Orbitofrontal Area

Disinhibition, irritability, lability, euphoria, and lack of remorse
Impaired insight and judgment
Distractible
looks like Antisocial PD, intermittent explosive disorder, and episodic dyscontrol syndrome

18

Dysfxn of Dorsolateral area

Deficiency in planning, monitoring, flexibility, and motivation
Can't see foresight and feedback
can't maintain goal-directedness, focus or sustained effort
inattentive and undermotivated
linger on trivial thoughts

19

Caudate functions

only allows goal directed movements
without it you do random motions --> choreoform movements

20

Folic Acid Deficiency

dialysis, heavy smokers, pregnancy, celiac disease

21

Beta sleep waves

13+ Hz
symmetric on both sides and most active in frontal lobe
closely linked to motor behavior but is attenuated with motor behavior

22

Seen in Active/Busy/Anxious thinking

low amplitude, with multiple, varying frequencies,
seen in active concentration
look for Rhythmic beta w/ dominant set of frequencies assoc w/ various pathologies and drug effects --> BZD

23

Delta waves

highest amplitude, lowest wave length
normally seen in babies
seen focally in subcortical lesions
and in gen distribution w/ diffuse lesions, metabolic encephalopathy, or deep midline lesions

24

Theta waves

younger children, seen in medication that makes you drowsy
seen in creative states
