| Authors | Year | Number | Memory paradigms | Summary | Remarks |
|
| Rabin et al. [34] | 2004 | 35 (20 Rt/15 Lt) | Complex visual scene encoding | Significant inverse correlation between activation ipsilateral to temporal lobectomy and memory outcome. No significant correlation in the contralateral activation | fMRI ARs correlated significantly with memory lateralization by IAT |
|
| Richardson et al. [37] | 2004 | 10 (all Lt) | Verbal memory encoding | Relatively greater verbal memory encoding activity in left HC compared with right HC, as measured using fMRI, predicts the extent of verbal memory decline in the same subjects | Material specific (verbal) |
|
| Richardson et al. [35] | 2006 | 30 (all Lt, 12 underwent ATL) | Verbal memory encoding | Functional adequacy of left HC best predicts postoperative memory outcome in left HS | Material specific (verbal), event related |
|
| Binder et al. [40] | 2008 | 60 (all Lt) | Language | Lateralization of language is correlated with lateralization of verbal memory | Wada memory testing is insufficiently reliable |
|
| Powell et al. [49] | 2008 | 15 (7 Rt/8 Lt) | Encoding of words (verbal), pictures, and faces | Relatively greater ipsilateral activation had greater memory decline | Supports the functional adequacy theory of HC function |
|
| Frings et al. [50] | 2008 | 22 (10 Rt/12 Lt) | Encoding and recognition of object locations | Positive correlation between the degree of ipsilaterality lateralized HC activation and postsurgical verbal memory decline | Nonverbal paradigm predicts postsurgical verbal memory decline |
|
| Binder et al. [36] | 2010 | 67 (37 Rt/30 Lt) | Language and scene memory encoding | Risk of verbal memory decline is more closely correlated with language lateralization than with overall asymmetry of episodic memory processes | Language paradigm to predict verbal memory decline |
|
| Bonelli et al. [39] | 2010 | 72 (31 Rt/41 Lt) | Encoding of words (verbal), pictures, and faces | Preoperative memory fMRI was the strongest predictor of verbal and visual memory decline | Memory fMRI in prediction of both postsurgical verbal and visual memory decline |
|
| Dupont et al. [51] | 2010 | 25 (14 Rt/11 Lt) | Scene encoding and recognition | fMRI activation during a delayed-recognition task is a better predictor of individual postoperative verbal memory outcome than is the Wada test | Only one study revealed marked discordant LI between memory fMRI and Wada test (only 48% of the patients showed concordant result) |
