Frontostriatal deficit in Motor Neuron Disease/Amyotrophic Lateral Sclerosis (MND/ALS)

So far, cognitive derangements in MND/ALS have not been widely studied. Nevertheless, it seems that in subgroups of patients cognitive functions are impaired in different degree, so that often at least two sub-types of the syndrome are reported: Motor Neuron Disease/Amyotrophic Lateral Sclerosis/Dementia Syndrome (MND/ALS/DS) and Motor Neuron Disease/Amyotrophic Lateral Sclerosis/ Aphasia Syndrome (MND/ALS/AS. A third subtype showing both symptoms of cognitive impairment may be identified in subgroups of patients and denominated Motor Neuron Disease/Amyotrophic Lateral Sclerosis/Dementia-Aphasia Syndrome (MND/ALS/DAS). Frontostriatal system is reported as a network heavily damaged in MND/ALS/DS, MND/ALS/AS, MND/ALS/DAS. The system is plausibly responsible of motor skills and verbs production, hence to become aware of a possible frontostriatal deficit in subgroup of MND/ALS patients might consent us to link at the brain level (motor) action and verbs and possibly ideomotor praxia and verbs. We have used Goal-Oriented Perception Task (GOPT) and Action Fluency Task (AFT) in order to detect with some accuracy impairments related to gestaltic analysis directed toward a goal, and verb retrieval deficits possibly underlying executive system dysfunction that destabilizes the ability to mentally coordinate the information associated with a verb. These tests should consent to detect possible frontostriatal derangements. We have tested 10 MND/ALS patients and 10 healthy subjects matched fore age, sex and laterality. AFT showed that 3 out of 6 patients are heavily impaired in this test (6.3 (mean) verbs generated vs 13.3 of the control group). GOPT detected a remarkable impairment in all patients: p=0.0021 (grammatical side), p=0.0002 (perceptual side). Reported frontostriatal deficit in MND/ALS seems confirmed by this study, and probably it is more easily detected by GOPT than by AFT

A Giant Lipoma In The Hand - Report Of A Rare Case

A 38 years old male patient presented with a large painless swelling in the right palm with ultrasound examination suggestive of fatty nature of the swelling MRI showing a well-circumscribed soft tissue swelling in the deep palmar space. The giant tumor of 6.5 X 4 cm was excised and the patient was symptom free two years following the surgery

Representation, Rightness, and the Fringe

So the central question here is phenomenological: What is the nature of the aesthetic zap? For it is this experience, or its promise, which gives art such a deep hold on human life. But the issue of representation, while secondary, is still pregnant with cognitive implications: Why is representation, of all the devices available to an artist, more likely to shift the odds in favour of eliciting and/or intensifying aesthetic experience? Assuming a Darwinian view of our species, it is likely that the answer to both questions will come from understanding how our capacity to enjoy art grows out of normal cognition

The Fringe: A Case Study in Explanatory Phenomenology

William James’ greatest achievement is, arguably, his analysis of the fringe — or, as he sometimes called it, transitive experience. In trying to understand this vague, elusive, often peripheral aspect of consciousness, James broke new ground. But in so doing he also began to lay down the first stratum of a radically new methodology, one that intersects first- and third-person findings in such a way that each is able to interrogate the other, and so further our understanding of both....\ud \ud But I think it is important to see that explanatory phenomenology can be completely scientific without necessarily having to (1) consider the neural substrate, (2) employ reductive arguments, or (3) operate at the third-person level. If I am right, explanatory phenomenology can be a remarkably plastic member of the set of first-person methodologies for the study of consciousness

There’s More That Binds Us Together Than Separates Us : Exploring the Role of Prison-University Partnerships in Promoting Democratic Dialogue, Transformative Learning Opportunities and Social Citizenship

In this paper we argue that education – particularly higher education (HE) - has the potential to offer socially, economically and culturally transformative learning opportunities–cornerstones of social citizenship. Yet, for prisoners, the opportunity to engage in HE as active citizens is often limited. Using a Freirean model of democratic, pedagogic participatory dialogue, we designed a distinctive prison-University partnership in which prison-based learners and undergraduate students studied together. The parallel small-scale ethnographic study, reported here, explored how stereotypes and ‘Othering’ - which compromise social citizenship - could be challenged through dialogue and debate. Evidence from this study revealed a positive change in ‘de-othering’ attitudes of participants was achieved. Furthermore, participants reported growth in their sense of empowerment, agency, and autonomy–cornerstones of social citizenship. Findings from this study contribute further evidence to the developing body of knowledge on the value of partnerships and dialogue in prison education. We conclude that policy makers, and respective institutions, need to work harder to establish prison-University partnerships, thus providing the space for real talk to take place

The biopsychology of maternal behavior in nonhuman mammals

The term “maternal behavior,” when applied to nonhuman mammals, includes the behaviors exhibited in preparation for the arrival of newborn, in the care and protection of the newly arrived young, and in the weaning of those young, and represents a complex predictable pattern that is often regarded as a single, comprehensive, species-specific phenomenon. Although the delivering first-time mammalian mother is immediately and appropriately maternal, a maternal “virgin” with no prior exposure to young does not show immediate and appropriate behavior toward foster young. Nevertheless, the virgin female, and indeed the male, possess the neural circuitry that underlies the pattern referred to as maternal behavior, despite not exhibiting the pattern under normal circumstances. At parturition, or after extensive exposure to young, what emerges appears to be a single stereotyped maternal behavior pattern. However, it is actually a smoothly coordinated constellation of simpler actions with proximate causes that, when sequenced properly, have the appearance of a motivated, purposive, adaptive, pattern of caretaking. Over the past 50 years, much research has focused on finding the principal external and internal factors that convert the nonmaternal behavior patterns of the nonpregnant nullipara, the virgin, to the almost immediate and intense maternal behavior characteristic of the puerpera, the mother. This review is an attempt to summarize the many comprehensive, even encyclopedic, reviews of these factors, with an emphasis on brain mechanisms, and to highlight the gaps that remain in understanding the processes involved in the almost immediate onset of maternal caretaking behaviors observed in mammals at delivery. Where possible, the reader is directed to some of those excellent reviews

Effects of Lateral Hypothalamic Lesions on Placentophagia in Virgin, Primiparous, and Multiparous Rats

Lesions of the lateral hypothalamus (LH) were produced in pregnant and nonpregnant female rats through chronically implanted electrodes to investigate the effect of LH damage on placentophagia. Other variables investigated were prior parturitional experience and stimulus properties of the placenta. Lesions were produced under ether anesthesia 24 hr. prior to parturition in pregnant females and 24 hr. prior to placenta presentation in nonpregnant females.\ud The LH lesions produced aphagia to a liquid diet. Pregnancy was not a significant variable in the initiation of placentophagia, but prior parturitional experience was a critical variable. Virgin and primiparous females did not exhibit placentophagia following LH damage, but multiparous females would eat placenta whenever the opportunity arose, independently of LH damage and pregnancy

A participatory methodology for large scale field trials in the UK

Farmer participation was essential in developing a uniquely useful set of wheat variety trials data on a wide range of organic farms over two years. Although the trials were successful, it became clear that some of the participating farmers felt there were some limitations in the process. These included a lack of ownership in the project and a concern for more researcher help. It was clear that a greater time in-vestment was needed at the start of the project to help with farmer understanding and ownership. De-spite the negative comments, farmers appreciated their involvement, particularly in contrasting their own views and information with that from the wider scene. Farmer participation is essential for systems-level research and this project helped to develop a small core of trained farmers and researchers

Placentophagia in Nonpregnant Rats:\ud Influence of Estrous Cycle Stage and Birthplace

Prior parturitional experience and genotype have previously been found to affect the proportion of nonpregnant female rats and mice that will eat foster placenta. The present series of experiments was designed to investigate the influence of estrous cycle stage on placentophagia in rats. Foster placenta was presented to nonpregnant Long-Evans females, purchased from a commercial breeder, for 15 min on 5 consecutive days. We found that virgin placentophages were most likely to have eaten placenta on the first presentation, unless the first presentation occurred during proestrus. In fact, virgins would not eat placenta for the first time during proestrus, regardless of test-day. However, once they had eaten placenta, either in a nonproestrus stage, or, in the case of primiparae, during parturition, they would eat placenta during proestrus. Long-Evans rats born in our laboratory differed from the purchased rats, manifesting an incidence of placentophagia that was too low to be analyzed by stage of the estrous cycle; when tested as primiparae, however, there were no differences between the two groups

Perinatal maternal and neonatal behaviour in\ud the captive reticulated giraffe

A captive reticulated giraffe was observed constantly for three weeks prior to, and periodically for 90 days subsequent to, the birth of her calf. Extensive observations were made of the birth sequence, feeding, drinking, sleeping and one instance of an infant distress call, as well as observations of the initiation of maternal behaviour (including licking, nursing, placentophagia, and what appeared to be helping the calf to stand, guiding the calf's movements, and attempts to respond to the calf's distress call)
