Visual recognition memory: A double anatomo-Functional Dissociation.
Hippocampus, 2011Co-Authors: Emmanuel J Barbeau, Jérémie Pariente, Olivier Felician, Michèle PuelAbstract:There is an ongoing debate regarding the respective role of anterior subhippocampal structures and the hippocampus in recognition memory. Here, we report a double anatomo-Functional Dissociation observed in two brain-damaged patients, FRG and JMG. They both suffered from complete destruction of left MTL structures. In the right hemisphere however, FRG sustained extensive lesions to the hippocampus sparing anterior subhippocampal structures, while JMG suffered from the reversed pattern of lesion, i.e., extensive damage to anterior subhippocampal structures but preserved hippocampus. FRG was severely amnesic and failed all recall tasks involving visual material, but exhibited normal performance at a large battery of visual recognition memory tasks. JMG was not amnesic and showed the opposite pattern of performance. These results strongly support the view that right anterior subhippocampal structures are a critical relay for visual recognition memory in the human. © 2010 Wiley-Liss, Inc.

RAPID COMMUNICATION Visual Recognition Memory: A Double Anatomo-Functional Dissociation
2010Co-Authors: Emmanuel J Barbeau, Olivier FelicianAbstract:There is an ongoing debate regarding the respective role of anterior subhippocampal structures and the hippocampus in recogni- tion memory. Here, we report a double anatomo-Functional Dissociation observed in two brain-damaged patients, FRG and JMG. They both suf- fered from complete destruction of left MTL structures. In the right hemisphere however, FRG sustained extensive lesions to the hippocam- pus sparing anterior subhippocampal structures, while JMG suffered from the reversed pattern of lesion, i.e., extensive damage to anterior subhippocampal structures but preserved hippocampus. FRG was severely amnesic and failed all recall tasks involving visual material, but exhibited normal performance at a large battery of visual recognition memory tasks.

Functional Dissociation of pre-SMA and SMA-proper in temporal processing.
NeuroImage, 2011Co-Authors: Michael Schwartze, Kathrin Rothermich, Sonja A. KotzAbstract:The ability to assess temporal structure is crucial in order to adapt to an ever-changing environment. Increasing evidence suggests that the supplementary motor area (SMA) is involved in both sensory and sensorimotor processing of temporal structure. However, it is not entirely clear whether the structural differentiation of the SMA translates into Functional specialization, and how the SMA relates to other systems that engage in temporal processing, namely the cerebellum and cortico-striatal circuits. Anatomically, the SMA comprises at least two subareas, the rostral pre-SMA and the caudal SMA-proper. Each displays a characteristic pattern of connections to motor and non-motor structures. Crucially, these connections establish a potential hub among cerebellar and cortico-striatal systems, possibly forming a dedicated subcortico-cortical temporal processing network. To further explore the Functional role of each SMA subarea, we performed a meta-analysis of Functional neuroimaging studies by contrasting activations according to whether they linked with either sensory, sensorimotor, sequential, non-sequential, explicit, non-explicit, subsecond, or suprasecond temporal processing. This procedure yielded a set of Functional differences, which mirror the rostro-caudal anatomical dimension. Activations associated with sensory, non-sequential, and suprasecond temporal processing tend to locate to the rostral SMA, while the opposite is true for the caudal SMA. These findings confirm a Functional Dissociation of pre-SMA and SMA-proper in temporal processing.
