Functional neuroanatomy of verbal free recall: A replication study is a scientific article about a positron emission study.

James T. Becker, Mark A. Mintun, David J. Diehl, Jeffrey Dobkin, Adam Martidis, David C. Madoff, Steven T. DeKosky (1994). "Functional neuroanatomy of verbal free recall: A replication study". Human Brain Mapping 1(4): 284–292. doi: 10.1002/hbm.460010406.

It seeks to replicate studies by Grasby[1] and Paulescu[2] in 1993.

The study was included in the original BrainMap database as paper no. 52.

Group 1 of 12 right-handed normals with 5 males and 7 females were included in the study. The group was from 25 up to 40 years old.

Only four subjects where in each experiment.

[edit] Design

There were three phases with different tasks

  1. Phase 1 with four subjects
    1. Single-word repetition task
    2. 3-word repetition task
    3. 15-word free recall task
  2. Phase 2 with four other subjects
    1. Single-word repetition task
    2. 3-word repetition task
    3. 12-word recall task
  3. Phase 3 with yet four other subjects
    1. Single-word repetition
    2. 3-word repetion
    3. 12-word recall task
    4. Rest with fixation
