In Norway and Sweden, epilepsy has for many centuries been considered a strange and mysterious disease. The explanations of its causes have been many and imaginative. One being that epilepsy was caused by the hidden people inhabiting the woods and the mountains. To avoid the disease, these hidden people should not be annoyed. One commonly used treatment principle was to try to place the disease back to the ground, or passing the diseased through a hole or an opening in the nature. Fresh blood from criminals was also considered to have strong antiepileptic properties. In the Scandinavian countries, some of these folk beliefs have been very tenacious. © 2017 Elsevier Inc.

Recent behavioral and neuropsychological studies suggest that visuo-spatial memory for reaching and navigational space is dissociated. In the present fMRI study, we investigated the hypothesis that learning spatial sequences in reaching and navigational space is processed by partially segregated neural systems. To this aim, we adapted the Corsi block tapping test (CBT) and the walking Corsi test (WalCT); the latter is a modification of the CBT in which subjects observe and reproduce spatial sequences by walking in a room instead of tapping wooden blocks on a table. Subjects were scanned while learning supra-span sequences of spatial locations through observation of video clips in which an actor tapped the blocks within reaching space (CBT) or walked on tiles placed on a carpet (WalCT). A large cerebral network spanning from visual occipital to parietal to frontal areas was activated during learning of both the CBT and the WalCT sequences. Within this network right lingual gyrus, calcarine sulcus and dorsolateral prefrontal cortex were specifically associated with learning in navigational space, whereas left inferior temporal gyrus, lingual and fusiform gyrus and middle occipital gyrus were associated with learning sequences in reaching space. These results support the idea of a partial segregation between neural circuits for reaching and navigational space not only in the domain of perception and action planning but also in spatial learning and long-term memory. © 2013 Elsevier Ltd.

In "Epilepsy is Dancing", in Antony and the Johnsons' album "The Crying Light"(2009), the lyrics and accompanying music video depicts an epileptic seizure in which the person is transferred to another beautiful and magical world. This may be called "enchanted epilepsy" i.e., the experience of epilepsy as deeply nourishing and (positively) transforming, is conveyed not only in the lyrics but also the visual and auditory qualities of the video. The seizure in the video gives associations to Shakespeare's "A Midsummer Night's dream".If epilepsy appears in music lyrics, the focus is mostly on negative aspects of the illness, such as horror, fear and repulsive sexuality associated with the fits [1,2]. Contradictory to these lyrics, Anthony and the Johnsons' song is an example of a positive portrayal of epilepsy. It is open to a multitude of meanings, emotional valence and appraisal of epilepsy. By widening the experiential range associated with epileptic seizures, these lyrics highlight the inherently construed nature of epileptic experience. The song stands out in several ways. First, it describes epilepsy in positive terms, prioritising the euphoric, ecstatic, potentially empowering and enhancing aspects of epileptic seizures. Second, the lyrics and accompanying video point to divine experiences associated with epileptic seizures. Through the lyrics and the music video we are, as an audience, able to sense a snicket of an epileptic seizure, but also the universal experience of loosing control. © 2015 Elsevier Inc.

Ian Curtis was the front man of the post-punk band Joy Division. He suffered from epilepsy and actively incorporated his experiences of the disease in his lyrics. Curtis had frequent epileptic seizures, both on and off stage. After dying from suicide in 1980, he became a legend in the post-punk milieu. The impact which the epilepsy, the epilepsy treatment, and comorbid depression had on his artistic life and premature death is not well known. © 2015 Elsevier Inc.

We studied pre-movement cortical activity related to praxic actions performed at self-paced rate and having ecological meanings and functions. Motor-related cortical potentials were recorded using 64-channels EEG in two experiments. Experiment 1 included 15 subjects performing in separate blocks two object-oriented actions: grasping a tea-cup and impossible grasping of a tea-cup (same goal but the grasp was mechanically hindered). Experiment 2 included a subset of 7 subjects from Exp. 1 and the action was reaching a tea-cup; this control condition had a different goal but was kinematically similar to impossible grasping. Different activity patterns in terms of onset, amplitude, duration and, at least in part, sources were recorded in the preparation phase (BP component) according to the specific action and to the possibility of accomplishing it. The main result is that parietal areas were involved in grasping preparation (called " posterior" BP) and not in reaching and impossible grasping preparation. The anterior frontal-central activity (called " anterior" BP) during preparation for grasping started earlier than the other two conditions. The cortical activity during preparation for reaching was similar to that for impossible grasping, except for a frontal activity only detected in the latter condition. It is concluded that the action preparation, even in its early phase, is affected by action meaning and by the awareness of being able to perform the requested action. © 2011 Elsevier B.V.

We investigated the movement related cortical potentials (MRCPs) associated with self-paced horizontal voluntary saccades and evaluated their cortical sources by applying dipole model. A fixation point and two targets (6° of eccentricity in the left and right fields) were continuously displayed on a screen. A first group (15 subjects) performed a saccade toward one of the lateral targets immediately followed by a re-centering saccade. A second group (15 subjects) performed a saccade followed by a long fixation (few seconds) before a re-centering. Results showed a sequence of activities in contralateral Intra-Parietal Sulcus (IPS), Supplementary Eye Fields and Frontal Eye Fields. In the case of long-fixation-saccades, an additional source in ipsilateral IPS was detected in the planning phase. The amplitude and timing of the planning phase, associated with BP components, were influenced by task demands. Similarity and difference between MRCPs for eyes and limbs movements are also presented. © 2012 Elsevier B.V.

The optic flow generated when a person moves through the environment can be locally decomposed into several basic components, including radial, circular, translational and spiral motion. Since their analysis plays an important part in the visual perception and control of locomotion and posture it is likely that some brain regions in the primate dorsal visual pathway are specialized to distinguish among them. The aim of this study is to explore the sensitivity to different types of egomotion-compatible visual stimulations in the human motion-sensitive regions of the brain. Event-related fMRI experiments, 3D motion and wide-field stimulation, functional localizers and brain mapping methods were used to study the sensitivity of six distinct motion areas (V6, MT, MST+, V3A, CSv and an Intra-Parietal Sulcus motion [IPSmot] region) to different types of optic flow stimuli. Results show that only areas V6, MST+ and IPSmot are specialized in distinguishing among the various types of flow patterns, with a high response for the translational flow which was maximum in V6 and IPSmot and less marked in MST+. Given that during egomotion the translational optic flow conveys differential information about the near and far external objects, areas V6 and IPSmot likely process visual egomotion signals to extract information about the relative distance of objects with respect to the observer. Since area V6 is also involved in distinguishing object-motion from self-motion, it could provide information about location in space of moving and static objects during self-motion, particularly in a dynamically unstable environment. © 2013 Pitzalis et al.

Purpose: Open-skill sports require high levels of visual attention and fast and flexible decision making and action execution. We evaluated whether these sports may counteract the well-known age-related declines in executive processing. Methods: Young and middle-age fencers and nonathletes were studied. Participants (N = 40) performed visual motor tasks while reaction times (RTs) and event-related potentials were recorded. Results: RTs were slower for the older subjects, but accuracy was not impaired. At event-related potential level, the late P3 component was delayed in older subjects, but those who participated in sports showed less delay. The RTs of middle-age and young fencers were comparable; the P1 latency of middle-age fencers was similar to that of the younger subjects; the N1 was enhanced in older, as well as younger, fencers; the N2 component of fencers had shorter latencies and larger amplitudes than nonathletes; and in no-go trials, the P3 component was enhanced in fencers independent of age. Conclusions: Overall, the practice of open-skill sports was associated with improvement of the executive functions that are already degraded at middle age. © 2012 by the American College of Sports Medicine.

Experts in a skill produce movement-related cortical potentials (MRCPs) of smaller amplitude and later onset than novices. This may indicate that, following long-term training, experts require less effort to plan motor skill performance. However, no longitudinal evidence exists to support this claim. To address this, EEG was used to study the effect of motor skill training on cortical activity related to motor planning. Ten non-musicians took part in a 5-week training study learning to play guitar. At week 1, the MRCP was recorded from motor areas whilst participants played the G Major scale. Following a period of practice of the scale, the MRCP was recorded again at week 5. Results showed that the amplitude of the later pre-movement components were smaller at week 5 compared to week 1. This may indicate that, following training, less activity at motor cortex sites is involved in motor skill preparation. This supports claims for a more efficient motor preparation following motor skill training. © 2012 Wright et al.

The Halstead Category Test-ComputerVersion (HCT-CV)was developed with the goal of adapting the HCTto the computer while maintaining all essential features of the original test. We compared the HCT-CV results from clinical neuropsychological evaluations of 25 patients who were matched on a pairwise basis with 25 patients previously tested with the original version. Matching was done on age, education, and diagnosis. Results of group comparisons showed that the HCT-CV performed comparably with the original version, with mean score differences of ,2 points. Correlations with the other subtests from the Halstead-Reitan Neuropsychological Test Battery were also found to be comparable. Results suggest that the HCT-CV can be considered a satisfactory and comparable version of the HCT, while providing advantages in terms of ease of use and portability. © The Author 2013.
