“…The emotional context in which a stimulus is encountered can markedly affect the memory trace of that stimulus. Indeed our visual system gradually modifies the way it processes sensory stimulation according to prior experience [60,77,79,93]. Hung et al demonstrated how the early amygdala activation indicates a fast and an automatic response, independent of the location of the fearful stimuli in the visual field [46].…”

Recent anatomical and DTI data demonstrated new aspects in the subcortical occipito-temporal connections. Although a direct (inferior longitudinal fasciculus, ILF) pathway has been previously described, its fine description is still matter of debate. Moreover, a fast and direct subcortical connection between the limbic system and the occipital lobe has been previously recognized in many functional studies but it still remains poorly documented by anatomical images. We provided for the first time an extensive and detailed anatomical description of the ILF subcortical segmentation. We dissected four human hemispheres with modified Klingler's technique, from the basal to the lateral occipito-temporal surface in the two steps, tracking the ILF fibers until their cortical termination. Pictures of this direct temporo-occipital pathway are discussed in the light of recent literature regarding anatomy and functions of occipito-temporal areas. The dissection confirmed the classical originating branches of ILF and allowed a fine description of two main subcomponent of this bundle, both characterized by separate hierarchical distribution: a dorsal ILF and a ventral ILF. Moreover, a direct pathway between lingual cortex and amygdala, not previously demonstrated, is here described with anatomical images. Even if preliminary in results, this is the first fine description of ILF's subcomponents. The complex but clearly segregated organization of the fibers of this bundle (dILF and vILF) supports different level of functions mediated by visual recognition. Moreover, the newly described direct pathway from lingual to amygdala (Li-Am), seems involved in the limbic modulation of visual processing, so it may support physiological conditions the crucial role of this connection in human social cognition. In pathological conditions, on the other hand, this may be one of the hyperactivated pathways in temporo-occipital epileptic and nonepileptic syndromes.

“…At the electrophysiological level, the earliest wave of cortical activation following stimulus onset corresponds to the C1, generated in the calcarine fissure (V1; Foxe & Simpson, 2002;Jeffreys & Axford, 1972;Kelly, Schroeder & Lalor, 2013). While motivational and emotional effects have been reported at this early processing stage (Morel, Beaucousin, Perrin, & George, 2012;Stolarova, Keil & Moratti, 2006), effects of reward and punishment on early sensory processing in human V1 have never been compared at the electrophysiological level when presented within the same task. Exploring motivational effects on early visual processing with Event-Related Potentials (ERPs) is complicated by the fact that stimuli with an intrinsic motivational value (e.g., images of babies or spiders) can hardly be matched along low-level properties.…”

“…However, in a follow-up MEG study, we used another paradigm, which allowed us to show that very early repetition effects can extend to associative emotional memory effects (Morel et al 2012). In this paradigm, we used only neutral faces, which were associated with an emotional context on their first encounter.…”

“…The reported effects were not related to any behavioural outcome. That is, the studies used either incidental tasks unrelated to face emotion and repetition factors (Morel et al 2009, 2012)—therefore not allowing to test for the potential behavioural influence of these factors—or an explicit task of social categorization that failed to demonstrate social category learning (Gamond et al 2011). Therefore, it is important to emphasize that the functional role of the very early modulation of information processing in association with emotion, social category, and experience is unclear.…”

Faces are key social stimuli that convey a wealth of information essential for person perception and adaptive interpersonal behaviour. Studies in the domain of cognitive, affective, and social neuroscience have put in light that the processing of faces recruits specific visual regions and activates a distributed set of brain regions related to attentional, emotional, social, and memory processes associated with the perception of faces and the extraction of the numerous information attached to them. Studies using neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have allowed localizing these brain regions and characterizing their functional properties. Magnetoencephalography (MEG) and electroencephalography (EEG) techniques are complementary to fMRI in that they offer a unique insight into the temporal dynamics of mental processes. In this article, I review the contribution of neuroimaging techniques to the knowledge on face processing and person perception with the aim of putting in light the extended influence of experience-related factors, particularly in relation with emotions, on the face processing system. Although the face processing network has evolved under evolutionary selection pressure related to sociality-related needs and is therefore highly conserved throughout the human species, neuroimaging studies put in light both the extension and the flexibility of the brain network involved in face processing. MEG and EEG allow in particular to reveal that the human brain integrates emotion- and experience-related information from the earliest stage of face processing. Altogether, this emphasizes the diversity of social cognitive processes associated with face perception.
