ANTEROGRADE AMNESIA

RETROGRADE AMNESIA KORSAKOFF’S SYNDROME BILATERAL REMOVAL OF MEDIAL TEMPORAL LOBE – H.M. Preserved Areas of Functioning in H.M.:

Pre-illness memory

New Learning Capacities CONCLUSIONS DRAWN BY MILNER:

1) hippocampus is not the site of long-term memory storage, nor is it needed to access long-term memories

2) hippocampus is not the site of immediate (short-term) memory storage

3) hippocampus is involved in converting short-term memories to long-term

Broca’s aphasia

1. agrammatism - difficulty in using grammatical constructions (e.g., -ed, have)

2. anomia - word-finding difficulty

3. articulation problems - mispronunciations

Wernicke’s aphasia 1. Recognition of spoken words - "pure word deafness" 2. Comprehension of word meaning - damage to posterior language area 3. Ability to convert thoughts into words Meaning of words is stored in appropriate association cortex Conduction Aphasia Anomic Aphasia Table 16.1 is a VERY nice summary of the above information!

Pure Alexia

Reading Dyslexia - faulty reading

1. surface dyslexia

2. phonological dyslexia 3. spelling dyslexia 4. direct dyslexia 5. comprehension without reading Writing deficits may involve:

1. problems with motor control

2. problems with spelling - involves deficits in either: Table 16.2 is a VERY nice summary of the above information!
