“…Rather, the participants had to learn to 23 relate these spatial patterns to the pre-defined categories and their labels during the supervised learning procedure. The observed advantage of the RH-lesioned group (i.e., patients with intact LH) in Experiment 1 therefore conforms to the well-documented superiority of the left hemisphere for the processing of familiar stimulus material (e.g., Marzi & Berlucchi, 1977), whereas the relative advantage of the LH-lesioned group (i.e., patients with intact RH) in Experiment 2 appears compatible with previous work postulating a competence of the right hemisphere for the analysis of novel stimuli (e.g., Marzi & Berlucchi, 1977;Goldberg & Costa, 1981;Marzi et al, 1985;Laeng & Rouw, 2001). A potential problem for this explanation is the difference between the two groups with regard to generalization to contrast reversal.…”

“…In particular, according to Goldberg and Costa (1981) semantic memory is mainly mediated by the left hemisphere because of the intrinsically propositional nature of its contents, which makes the verbal code the most suited to memory storage. By contrast, the right hemisphere supports autobiographical episodic memory because of the close relationship between visual imagery (mainly mediated by the right hemisphere; Gardini et al, 2005) and the subjective experience of autonoetic consciousness, which supports the ecphory of previously experienced autobiographical events (Calabrese et al, 1996;Piolino et al, 2007).…”

Patients with damage to the mesial and anterior portions of the temporal lobes suffer from a memory impairment involving both anterograde and retrograde amnesia. In the retrograde domain, it has been suggested that the relative severity of autobiographical and nonautobiographical memory impairment may depend on the prevalent side of the temporal damage. Here we present two patients suffering from damage to the mesial and anterior portions of the temporal lobes (hippocampal formation, parahippocampal gyrus and polar cortex) as a result of herpes encephalitis. In the first case, A.S., damage predominantly affected the right temporal lobe, whereas in the second patient, R.S., the damage was bilateral but more severe on the left side. A detailed investigation of the retrograde memory deficit demonstrated a partial double dissociation between the two patients, with A.S. almost exclusively impaired in the autobiographical domain (both episodic and semantic) and R.S. with poor performances in all domains, but much more severe in the nonautobiographical (both public events and general semantic knowledge) than in the autobiographical one. These findings reinforce the view of specialization of right and left temporal lobes in the retrieval of retrograde autobiographical and nonautobiographical memories, respectively.

“…Recruiting medial temporal lobe structures connected with prefrontal areas also results in the self-referential nature of mental activity and several possibilities of mental time traveling, such as remembering the past or anticipating the future. There may be a degree of hemispheric asymmetry, with short-distance connections predominating in the left hemisphere and long-range loops predominating in the right hemisphere (Goldberg & Costa, 1981). According to Goldberg and Costa, the left hemisphere predominance of short range cortico-cortical connections could explain the involvement of this hemisphere with syntactic and phonological aspects of language, whereas more widespread connections in the right hemisphere would explain its role in pragmatics and text processing (see also Rourke, 1995).…”

Neuropsychological diagnosis requires a structure-function correlation model or a "Conceptual Nervous System." The unpredictably variable, widespread, and multifocal nature of pathological changes in multiple sclerosis (MS) challenges the neuropsychological localizationist assumption. To be adapted to MS pathological and clinical heterogeneity, a Conceptual Nervous System should explain impairments associated with multifocal, subcortical, and white matter lesions that cause information processing slowing and working memory/executive function impairment. Our main goal in this theoretical study was to develop a Conceptual Nervous System for MS by integrating current neuropsychological conceptions of structural-functional correlations in MS with a model of conscious mental activity developed by Ernst Pöppel , based on periodic reentrant activity between cortical and subcortical structures. Neuropsychological profiles in MS can be explained by both threshold and multiple disconnection mechanisms. The Conceptual Nervous System encompasses a functional and structural model of the human brain-mind. The functional model classifies mental function into material and formal. Material/semantic functions are modularly organized, and their impairment causes classical focal neuropsychological symptoms. Multiple sclerosis preferentially impairs formal/syntactic function related to widespread patterns of activation and temporal organization. The structural model specifies the system anatomically functions. The neuropsychological adequacy of the proposed Conceptual Nervous System to MS is analyzed by comparing its predictions to results of extant metaanalytic studies.
