The mouse brains were excised and collected for histopathological study and immunological analyses. The three techniques used had the same sensitivity for virus detection in bat brains (100 %). Studies have demonstrated that our brains contain neurally based 'body schema', or representations of our bodies. Our brains are plastic in the sense of being adaptable, able to learn to operate in new ways as the environment demands. The account also implies we couldn't survive severe amnesia or strokes that render our brains infant-like and in need of retraining. Replication of distinct scrapie prion isolates is region specific in brains of transgenic mice and hamsters. Two other chapters in this section cover the neuron, which is the brain's ' microprocessor ' and the many different neurotransmitter systems. One month after immunization brains were processed to detect b-galactosidase expression by immunohistochemistry. One boy tells another that their teacher: is always telling us to use our own hands and brains. How many subtypes of glia exist in the brains of invertebrates and mammals? Since every human being's history and circumstances are different, each brain's wiring is going to be quite unique. The idea that psychologists' choice of experimental paradigms has representation in the animals' brains is too, too much! Also, big brains would still remain adaptive even without niche construction. Three times he has infected our blood and brains with the bacillus of perfection. If the number of languages is finite, the enumeration might be inscribed as such in the brains of human infants. The small subset of species possessing brains, including humans, is characterized by a diverse array of specialized evolved psychological mechanisms. The way perceptions are represented in our brains is far from settled, but the rules of kinematic geometry could not be applied to some possibilities. Not yet knowing how brains develop, we do not really know what the units are that selection can target. Likely, most cortical regions and their interconnecting pathways in rodent and primate brains will be different to accommodate this order-related difference. Thus, brains of necessity become bigger in order to accommodate new functions. The extremely divergent nature of these features from that of other mammalian brains continues to be the centerpoint of active debate about dolphin intelligence. When considering hominid evolution, attempts to understand how evolution produces larger brains is of prime interest. Our intuitions tend to be very different when discussing human brains and insect brains, yet the problems are often common ones. Early motor control research often assumed that the brain's commands were in terms of joint torques, angles, and so forth. Do they find it distressing when art museums fail to hang pictures of brains on their walls? Probably brains are even more than that, namely, complex dynamical systems exhibiting something like a "liquid" architecture. The generality of this process is remarkable, as is its potency across the vast range of the brain's evolutionary mechanisms. Humans, with their large brains relative to body size, are an example of this situation. Such connections may well function to integrate information across the brain's perceptual and conceptual faculties, without recourse to a linguiform medium of thought. What remains to be discovered, however, is what form these constraints take in terms of the brain's structural properties. Accelerated amyloid deposition in the brains of transgenic mice coexpressing mutant presenilin 1 and amyloid precursor proteins. Linked regularities in the development and evolution of mammalian brains. Evoked potential studies of attention capacity in human frontal lobe brains. If we are tired and are "winding down" at the end of a day, our brains are presumably less activated. There is much here to stimulate those famously large brains with which humans are endowed. Our brains are divided into ten, and we are ten groups who are quarrelling. Individual differences in the reactivities of sympathetic and parasympathetic divisions of the brain's autonomic centres should therefore also be relevant to the efficiency of socialization. They can also assert that materialists are entitled to say precisely the same things about brains. What kind of special matter are brains made of, according to materialists ? The thalami from the brains of two normal subjects were used for generating maps of gene expression patterns in the serially-sectioned thalamus. Rats were intracardially perfused (10% formalin), brains were removed and stored for 1-2 days. Expanded ontogeny of neurotransmitters and their metabolites in the brains of fetal and newborn lambs. The brains were rapidly removed and snap frozen. First, he began to collect the brains of scholars, whereas the earlier nineteenth century knew only collections of skulls. He had weighed the brains of 29 normal men and found an average figure of 1323 grams. On the contrary, he started to collect radical brains and sought a material basis for their peculiarity. He wanted to study this problem by comparing the brains of hibernating animals, during sleep and awake periods. They thus lacked intelligence, athletic bodies, and brains. The brains from the cases used in the three transsynaptic protocols all underwent the same histological procedures. Perhaps most intriguing, might some of the developmental constraints have evolved as adaptations for the generation of functionally viable brains? In addition, he mentioned the weight of the brains of four eminent men, none of which he had ever seen. After per fusion, the brains were immediately removed and blocked in the coronal plane (5 mm thick). By far the most important and immediate context for decerebrating brains was, however, in response to the political pressures of animal protection and antivivisection movements. A cryoprotection method that facilitates cutting frozen sections of whole monkey brains from histological and histochemical processing without freezing artifact. There is abundant evidence now that neonatal brains are embarking on changes in organization that are highly responsive to stimulation from caregivers. Superficially, a computer might seem a useful analogy for how brains perceive and act in information-rich environments. Seeking half our brains: reflections on the social context of interdisciplinary research and development. There have been millions of other brains much like mine. We all know the importance of keeping our brains and bodies healthy and active, and of maintaining social support networks. In line with this, where the nature of the work was complex and employees were mainly ' brains ', greater sympathy, responsiveness and flexibility was reported. I find it more instructive, therefore, to compare the brains of animals with similar body sizes. Is there some hierarchy to this weeding-out process that might be different in brains of different size of maturational rate? The alternative is to take a braincentered approach, to assume that brains like ours are more likely than others to have these capacities. Thus, big brains are more likely than small brains to have excess neurons available for cognitive processing. Marsupials have the same event order, producing brains of different sizes, but the pace of neuronal production is slowed overall. Is a map of stars etched into the brains of indigo buntings to guide them south? The meeting is instead a match - a belonging-together - some match between reality and cognitive attunement, which may be repeated across monadological brains. Here, we investigate the phagocytic activity of microglia prepared from neonatal rat brains and macrophages prepared from rat bone marrow using flow cytometry. Astroglial cultures were prepared from brains of neonatal rats and maintained for 2-3 weeks. Our brains are well adapted to achieving control objectives in spite of inertia, friction and gravity. In other words, mental processes are viewed as being essentially identical with the brain's physical processes (and not the result of these physical processes). Following major insults, delirium occurs even among those with relatively healthy brains. Human brains are much larger than those of mice and, as in the case of naturally infected rodents, numbers are likely to be low. On the basis of the number of larvae recovered from individual brains of mice, the infected mice were divided into larval intensity groups. Big brains and complex behaviours, however, cannot be considered in isolation. The images of these minimally conscious brains were compelling, prompting all manner of speculation. Dystrophic calcification was a feature of some brains. Finally, neurophysiological studies have started to produce a wealth of data on the multimodal speech representations in the developing and mature brains. The project cannot be avoided, for the metaphysical consensus of the age insists that minds do not exist apart from brains - or, perhaps, comparable machines. Rat brains were then aldehyde-fixed and processed using standard methods. He also assumes that there are no essential differences between the brains of people from different societies or different historical periods. Moral restrictions precluded the dissection of brains of eminent men before the 1830s. Structural changes, in other words, occur within their brains on a large scale for nearly a month. In understanding brains, some of the crucial steps have been technical. Partnership became his slogan- the partnership of public and private brains and money. We have learned much about our own brains and vocal tracts, and those of our primate cousins. Their brains function; they are conscious and are able to do a variety of things; but they have been struck down, for example, by polio. When it tells our brains which way our heads are pointing, it affects our perception of stereo and quadraphonic sound. At an early stage, cells in the inner cell mass are not determined; they are not yet specified to form brains or toes. However, we know that the development of the brain's structure and function always occurs within an environmental context. Nevertheless, the brain's openness to environmental influence also creates a degree of vulnerability to early disruptions in development. Furthermore, activation maps can be misleading due to the structure of the brain's vascular system. The model has implications for how the brain's reading network might respond to variations in writing systems. One way to explore this question is to contrast the brains of individuals who differ in their vocabulary knowledge. Many people function homolaterally, using only some of the brain's capacity in any one situation. Pupils will have to listen hard, work hard and use their brains to master cross-rhythms, develop musical motifs and sustain their concentration in longer performances. Genes are the primary policy-makers; brains are the executives. These examples are from corpora and from sources on the web.
