The etiology of Alzheimer's dementia is, at best multifactorial. Before the emergence of cognitive impairment, symptoms such as thinning of the cortex, accumulation of β-amyloid, and decreased hippocampal volume are common. Hence, the accumulation of β-amyloid and hyperphosphorylated tau fibrillary tangles are two pathological hallmarks in Alzheimer's disease brains, but antibody therapy aimed to decrease β-amyloid has been a failure and, in most optimistic opinions, may delay somewhat disease progression. However, 31-38 % of subjects develop cerebral micro-hemorrhages in aducanumab therapy, an antibody to the amyloid beta plaque by Biogen. Genetics such as Apo E3/E3 have demonstrated defects in the blood-brain barrier in early-onset dementia...more

Conductive polypyrrole/chitin conduit with electric stimulation for nerve regeneration
Haishan Jiao, Jian Huang, Ying Chen, Yuening Song, and Dongyin Li
​
PPy/chitin composite conduits (CAP) were fabricated by tube casting using chitosan blended with microemulsion polymerized nano-PPy, which was modified by acetylation. Chitin conduits (CA) modified by acetylation from chitosan conduits without PPy were also prepared. Both CAP and CA conduits were used to bridge sciatic nerve defects with or without ES. Autologous nerve transplantation was used as a positive control. Electrophysiological and histological methods were measured. We found that: (1) injured nerve bridged with conduit and ES had improved regeneration compared with that bridged with conduit without ES; and (2) conductive conduit combined with ES was more effective in promoting nerve regeneration compared with non-conductive conduit, but was similar to autologous nerve. Our findings demonstrate that conduits of PPy/chitin conductive composite exhibit favorable properties for clinical use by promoting nerve regeneration and functional recovery.

Universal Intelligent Life, Artificial Intelligence, Our Evolutionary Difficulty, and Prospects for the Future
Franco Ivaldi and Nicola Smigliani
When we men and women try to represent a natural phenomenon with our own means, we tend to build around it a rigorous theoretical framework, which can sometimes be inconsistent with reality, similar to building a defense barrier against the fears and insecurities present in our lives. This leads to generate "dogmas", at the basis of the stalemate present in classical Science (and not only), unable to appreciate the Intelligent and Harmonious connection present in everything in this Universe, which leads a large number of men and women to prefer the permanence of a problem that they cannot explain, to an explanation that is difficult to understand, as it comes out
of their daily life made up of difficult problems, which could instead be solved if only we committed ourselves to doing so, with sacrifice and work. Science, to be consistent with Universal reality, cannot be closed in on itself, as if it was the heritage of its experts only, and cannot be separated from Philosophy and Ethics that guide it to ask the "right questions", otherwise it is like a building ...

Neurobiological circuits of anxiety in ASD: Exploring the complexities
L. A, Cacha
​
ASD does not include anxiety as one of its core features, which has its own unique and additional level of complexity. The prevalence of anxiety disorder is not considered a core characteristic, yet majority of individuals with autism exhibit clinically elevated levels of anxiety or suffer from at least one anxiety disorder, including obsessive-compulsive disorder. An individual who is anxious is more likely to suffer from excessive negative emotions, which are indicative of potential dysfunctions within the brain systems responsible for regulating negative emotions. Anxiety is believed to have a neurobiological component, and considerable research has long been conducted to determine how its arousal impacts behavioral development in typical situations. Investigation has focused on the structural development of the amygdala implicated in the neurobiology of autism. An overview of the role of the prefrontal cortex in modulation of amygdala function is presented in this paper, as well how differences in amygdala and prefrontal cortex connectivity may play a role in influencing the presentation of anxiety syndrome in the context of autism spectrum disorder.

The inference on information-carrying elements in the process of consciousness
​Majid Beshkar
​
Consciousness is a precognitive process in that no observer can establish any correlation with (and hence obtain any information from) it. It is an entropy-minimization process associated with minimizing quantum entropy and exporting its effect on the underlying neuronal medium as information-carrying elements. This process may give rise to consciousness from a neuronal medium through inference on information-carrying elements.

The Elemental Intelligence of the Cosmos and the Acoustic Quantum Code of ResonantCohe rence
Dirk K. F. Meijer & Franco Ivaldi
​​
In this article an analysis is carried out on the basic mechanisms inherent in the functioning of the living and conscious Universe, that seems permeated by an intrinsic intelligence. In this scenario, a primordial acoustic quantum code in the form of BSE-condensed polaron field is assumed to provide the conditions for the guided formation of the cosmos in which also Gravity and Dark energy forces were created. As to the latter, we submit that primordial proton/ electron composite units, covered with multiple phonons (forming quasi-particles), exhibit internal attractive and external repulsive features, thereby generating the forces of gravity and anti-gravity (dark
energy). Our earlier results indicate that the frequency pattern of the “Acoustic Quantum Code of Resonant Coherence” is fully in line with recently reported frequency values for cosmic gravitational waves, as well as for oscillations of ZPE field, at the macro-scale. With regard to brain function, at the micro-scale, interestingly, an almost perfect frequency fit of our algorithm was revealed for brain microtubular oscillations. These results on neuronal signaling, numerically support the Orch-OR consciousness theory. The present ...

The Illusion of Intrinsic Meaning: Reassessing Conscious experience
Thomas W. Loker
The illusion of intrinsic meaning in predictive coding through cognitive artifacts to minimize prediction errors points toward a functionalist attempt at understanding conscious experience. It examines how conscious experience serves functional roles in predictive coding and symbolic cognition systems within the brain. By addressing recent developments in diverse fields like cognitive neuroscience, philosophy, and artificial intelligence, we argue that conscious experience emerges from the need to construct coherent narratives for survival and decision-making. Additionally, the paper explores the implications for artificial intelligence, suggesting that artificial systems could develop analogous cognitive artifacts through predictive models without subjective awareness, contributing to a functionalist understanding of consciousness, and further advancing the discussion on the nature of conscious experience in biological and artificial systems.

Functional Outcomes After Spinal Cord Contusion Injury in Rats: The Influence of Age and Key Parameters
​Jonghoon Kang & Young S. Gwak
​
The complexity of sensory and motor dysfunctions following spinal cord injury (SCI) necessitates identifying key physical parameters that contribute to these outcomes. This study examines the effects of critical parameters on behavioral and physiological outcomes after spinal contusion in periadolescent (7 weeks) and adult (30 weeks) male Sprague-Dawley rats. A standardized injury of 150-kilodyne force and 1-second dwell time was induced at thoracic level 10. Actual Force (152.6 ± 0.6 and 154.4 ± 1.2 kdyn) and Velocity (121 ± 0.4 and 120.7 ± 0.6 mm/s) were consistent between groups, although Displacement (981.5 ± 35.9 and 1048.6 ± 30.4 µm) varied. The periadolescent group showed more rapid body weight loss (POD 4 vs. POD 7) and quicker locomotion recovery (POD 16 vs. POD 22), while the adult group exhibited faster onset of bladder dysfunction. By 40 days post-injury, all groups developed mechanical allodynia (p < 0.05), with thermal hyperalgesia significantly elevated in the periadolescent group (p < 0.05). Analysis of displacement subsets revealed that both Low and High displacement groups had similar levels of mechanical allodynia; however, the High displacement group experienced greater impairments in body

Spatiotemporal dynamics of intracellular calcium during speed tuning for directionality: the initial stage of cardinal direction selectivity
N.L. Iannella & R.R. Poznanski
Detecting moving objects is crucial in the animal kingdom and is fundamental to vision. In the vertebrate retina, starburst amacrine cells are directionally selective in terms of their calcium responses to stimuli that move centrifugally from the soma. The mechanism by which starburst amacrine cells show calcium bias for centrifugal motion is still to be determined. Recent morphological studies using fluorescent microscopy and immunostaining have shown that the endoplasmic reticulum is omnipresent in the soma, extending to the distal processes of starburst amacrine cells. Electron microscopy for ChAT SAC in adult rat retina unequivocally proves the presence of local endoplasmic reticulum. The submicron in diameter dendrites implies that the endoplasmic reticulum is not luminally connected between the soma and the distal tips. We construct a computational model of SAC dendrites with ER to simulate the Ca2+-induced Ca2+ release (CICR)-based calcium waves in the presence of unsaturated buffer to test the hypothesis that the CICR mechanism can sustain constant calcium wave propagation in the centrifugal direction...
BRIEF REPORT
On the transition from a sense of self to actualizing an intention
R. R. Poznanski
Action potentials are a part of neural activity, but defining neural action is far more complex. Generalizing specific cognitive tasks as neural is ineffective. Instead, this paper focuses on individual factors such as intentions in action or consciousness in action. The hard question of consciousness arises from how the brain's biochemistry interacts with the electromagnetic field to facilitate energy transduction, enabling various forms of information to sustain self-referential causal closure. This has important implications, especially when intentions in action become intentions through a process that involves a transition from the experience of acting out a thought to actualizing intentions. This transition is particularly relevant to subjective intentionality, precognitive and unreliable in forming intentions without understanding the biochemical and biophysical foundations. We propose that negentropic force drives the transition from experience to intentions. Experience such as subjective intentionality is a quantum-optical effect actuated by electromagnetic “sparks” in benzene rings and proton transfer in hydrophobic pockets ...
