Background: Late-delayed complications after radiotherapy (RT) results from an imbalance between cell lesions and the protective capacities of the CNS. Temozolomide (TMZ) after RT may represent a potent radiosensitizing regimen. Although radionecrosis (RN) of the anterior visual pathway has been documented, in our opinion this is the first report of reversible visual field loss associated with occipital lobe radionecrosis. Case observation: We report a patient who suffered a left lateral homonymous hemianopia one year after radiochemotherapy (RCT) for an infiltrative low grade fibrillary astrocytoma. The visual field deficit was completely reversible after one month. Visual field defects have been described after the use of conventional external beam therapy for lesions near the anterior visual pathway. The cortex is relatively spared after RT. Conclusions: Given the new scientific data, we suppose that neuroplasticity may play a role in the reversibility of visual field deficit. At this time there is no proven treatment of radionecrosis. Homonymous hemianopia caused by occipital lesions are attributable to vascular disease and tumors, but take into account radiation effects. The risk of neurogenic visual loss must be factored into the decision to irradiate the whole brain.

More and more research in recent years has focused on neurogenesis and neuroplasticity. The hippocampus is a key location of adult neurogenesis. Because this part of the brain is regulated by environmental variables, it must be mentioned the therapeutic potential for neurodegenerative illnesses and brain injuries. Furthermore, this information challenges the historical concept of a static brain and tries to demonstrate its flexibility, adaptability, and possibility for regeneration. Those mechanisms which are found in a variety of mammalian species, including humans, are important when it comes to adaptive learning and memory, thus providing insights into cognitive well-being and mental health. The discovery of the brain's dynamic nature represented by new neurons, marks a shift in the field of neurology with far-reaching potentials. This paper highlights the significant potential of adult neurogenesis when it comes to clinical applications such as Alz-heimer's disease.

The use and misuse of digital technologies among adolescents has been the focus of fiery debates among parents, educators, policy-makers and in the media. Recently, these debates have become shaped by emerging data from cognitive neuroscience on the development of the adolescent brain and cognition. "Neuroplasticity" has functioned as a powerful metaphor in arguments both for and against the pervasiveness of digital media cultures that increasingly characterize teenage life. In this paper, we propose that the debates concerning adolescents are the meeting point of two major social anxieties both of which are characterized by the threat of "abnormal" (social) behaviour: existing moral panics about adolescent behaviour in general and the growing alarm about intense, addictive, and widespread media consumption in modern societies. Neuroscience supports these fears but the same kinds of evidence are used to challenge these fears and reframe them in positive terms. Here, we analyze discourses about digital media, the Internet, and the adolescent brain in the scientific and lay literature. We argue that while the evidential basis is thin and ambiguous, it has immense social influence. We conclude by suggesting how we might move beyond the poles of neuro-alarmism and neuro-enthusiasm. By analyzing the neurological adolescent in the digital age as a socially extended mind, firstly, in the sense that adolescent cognition is distributed across the brain, body, and digital media tools and secondly, by viewing adolescent cognition as enabled and transformed by the institution of neuroscience, we aim to displace the normative terms of current debates.

The concept of mutual aid is central to the anarchist tradition, but also a source of controversy. This book's intervention is to consider solidarity and mutual aid at the intersection of politics and biology, developing out of the work of Catherine Malabou.
