In Poland storage of human biological samples takes place at most universities and scientific institutions conducting research projects in the field of biomedicine. The First International Biobanking Conference organized by the Ministry of Science and Higher Education in 2014 shed a light on the situation of Polish biobanking infrastructures. The country has around 40 large biorepositories, which store unique biological material such as whole brains, muscle fibers from patients with rare diseases, as well as thousands of samples from patients with lifestyle diseases...

Migraine is considered a disabling disorder with highly prevalence in population. Recent studies report that migraine patients have a cognitive decline associated to structural brain alterations. We search on PubMed and Web of Science databases and screening references of included studies and review articles for additional citations. From 519 studies identified, only 16 met the inclusion criteria. All studies were conducted on 1479 migraineurs (190 non-migraine headache and 11,978 controls subject) and examined the association between migraine and cognitive impairment...

Hypokinetic dysarthria (HD) occurs in 90% of Parkinson's disease (PD) patients. It manifests specifically in the areas of articulation, phonation, prosody, speech fluency, and faciokinesis. We aimed to systematically review papers on HD in PD with a special focus on (1) early PD diagnosis and monitoring of the disease progression using acoustic voice and speech analysis, and (2) functional imaging studies exploring neural correlates of HD in PD, and (3) clinical studies using acoustic analysis to evaluate effects of dopaminergic medication and brain stimulation...

Neuromodulators are endogenous neurochemicals that regulate biophysical and biochemical processes, which control brain function and behaviour, and are often the targets of neuropharmacological drugs. Neuromodulator effects are generally complex partly owing to the involvement of broad innervation, co-release of neuromodulators, complex intra- and extrasynaptic mechanism, existence of multiple receptor subtypes and high interconnectivity within the brain. In this work, we propose an efficient yet sufficiently realistic computational neural modelling framework to study some of these complex behaviours...

INTRODUCTION: This systematic review examined the association between genetics and risk for sustaining a traumatic brain injury. METHODS: Articles published in English from 1980 to July 2016 obtained from the online databases PubMed, PsycINFO®, MEDLINE®, EMBASE, and Web of Science. RESULTS: 5,903 articles were identified, 77 underwent full-text screening, and six were included in this review. Five studies examined the risk of concussion associated with Apolipoprotein E alleles (APOE-ε2 ,ε3 ,ε4,), and polymorphisms of the APOE promoter (rs405509), Brain Derived Neurotrophic Factor (BDNF, rs6265), and Dopamine Receptor D2 (DRD2, rs1800497) were each considered in two studies...

Uta-Susan Donges, Thomas Suslow
Alexithymia is a personality trait characterized by difficulties in recognizing and verbalizing emotions and the utilization of a cognitive style that is oriented toward external events, rather than intrapsychic experiences. Alexithymia is considered a vulnerability factor influencing onset and course of many psychiatric disorders. Even though emotions are, in general, elicited involuntarily and emerge without conscious effort, it is surprising that little attention in etiological considerations concerning alexithymia has been given to deficits in automatic emotion processing and their neurobiological bases...

Society expects that the wave of contemporary new discoveries in biological sciences will soon lead to novel treatments for human diseases, including many devastating brain disorders. Historically, medicinal chemists have contributed to drug discovery teams in ways that synergize with those from their partner sciences, and help transform new knowledge into the ultimate tangible asset: a new drug. The optimal balance of resources and the right strategy to minimize the risk of late clinical failure may differ for different therapeutic indications...

Recent work in computer science has shown the power of deep learning driven by the backpropagation algorithm in networks of artificial neurons. But real neurons in the brain are different from most of these artificial ones in at least three crucial ways: they emit spikes rather than graded outputs, their inputs and outputs are related dynamically rather than by piecewise-smooth functions, and they have no known way to coordinate arrays of synapses in separate forward and feedback pathways so that they change simultaneously and identically, as they do in backpropagation...

The complexity associated with deep interconnectedness in nature is beginning to be articulated and elaborated in the field of ecological studies. While some parallels to the psyche have been made and the field of Eco-psychology has been developing, Jung's explicit contribution by way of the image of rhizomes has not been considered in detail. Philosopher Gilles Deleuze acknowledges borrowing the term from Jung, though he disagreed with Jung's Empedoclean use of the term. The paper presents some fundamental properties of rhizomes along with contemporary scientific research on mycorrhizal (fungal) networks...

Argument This paper focuses on the uses of electroencephalograms (EEGs) in Mexico during their introductory decade from 1940 to 1950. Following Borck (2006), I argue that EEGs adapted to fit local circumstances and that this adjustment led to the consolidation of different ways of making science and the emergence of new objects of study and social types. I also maintain that the way EEGs were introduced into the institutional networks of Mexico entangled them in discussions about the objective and juridical definitions of social groups, thereby preempting concerns about their technical and epistemic limitations...

There is convincing evidence that abnormalities of regional brain function exist in Parkinson's disease (PD). However, many resting-state functional magnetic resonance imaging (rs-fMRI) studies using amplitude of low-frequency fluctuations (ALFF) have reported inconsistent results about regional spontaneous neuronal activity in PD. Therefore, we conducted a comprehensive meta-analysis using the Seed-based d Mapping and several complementary analyses. We searched PubMed, Embase, and Web of Science databases for eligible whole-brain rs-fMRI studies that measured ALFF differences between patients with PD and healthy controls published from January 1st, 2000 until June 24, 2016...

Mass spectrometry imaging (MSI) can uniquely detect thousands of compounds allowing both their identification and localization within biological tissue samples. MSI is an interdisciplinary science that crosses the borders of physics, chemistry and biology, and enables local molecular analysis at a broad range of length scales: From the subcellular level to whole body tissue sections. The spatial resolution of some mass spectrometers now allows nano-scale research, crucial for studies in nanomedicine. Recent developments in MSI have enabled the optimization and localization of drug delivery with nanoparticles within the body and in specific organs such as kidney, liver and brain...

BACKGROUND: Traumatic brain injury (TBI) survivors often report difficulties with understanding and producing paralinguistic cues, as well as understanding and producing basic communication tasks. However, a large range of communicative deficits in this population cannot be adequately explained by linguistic impairment. The review examines prosodic processing performance post-TBI, its relationship with injury severity, brain injury localization, recovery and co-occurring psychiatric or mental health issues post-TBI METHODS: A systematic review using several databases including MEDLINE, EMBASE, Cochrane, LLBA (Linguistics and Language Behaviour Abstract) and Web of Science (January 1980 to May 2015), as well as a manual search of the cited references of the selected articles and the search cited features of PubMed was performed...

INTRODUCTION: Every day millions of professionals use a countless number of technical words to refer to the different structures inside the skull. But few of them would know how to explain their origin. In this study we take an in-depth look into the etymological origins of some of these neuroanatomical terms. DEVELOPMENT: The study takes an etymological tour of the central nervous system. It is in no way meant to be an exhaustive, detailed review of the terms currently in use, but instead a means to familiarise the reader with the linguistic past of words like brain, hippocampus, thalamus, claustrum, fornix, corpus callosum or limbic system...

The development of rehabilitation has traditionally focused on measurements of motor disorders and measurements of the improvements produced during the therapeutic process; however, physical rehabilitation sciences have not focused on understanding the philosophical and scientific principles in clinical intervention and how they are interrelated. The main aim of this paper is to explain the foundation stones of the disciplines of physical therapy, occupational therapy, and speech/language therapy in recovery from motor disorder...

Neurotrophins particularly brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are crucial modulators in the neurodevelopment and maintenance of central and peripheral nervous systems. Neurotrophin hypothesis of schizophrenia (SCZ) postulated that the changes in the brains of SCZ patients are the result of disturbances of developing processes involving neurotrophic factors. This hypothesis was mainly supported by the abnormal regulation of BDNF in SCZ, especially the decreased peripheral blood BDNF levels in SCZ patients validated by several meta-analyses...

Anxiety is a psychiatric disorder with unknown neurobiology; however, neurotransmitters like gamma-amino butyric acid, norepinephrine and serotonin (5-HT) play crucial roles in mediating anxiety. Present drug modules pose dependence risk to the patient; hence, there is a great need to develop complementary therapies to fight this disorder. Aromatherapy has also been employed in ancient times for a number of mental disorders. Mahamrituanjay Mantra, Om triambkum yajamahe, sughandhim puushtivardhanam, urvarukmev vandhanaat, mrityu mokshay mamritaat!!!!, the part of veda enlightens that aroma gives rise to good health (sughandhim puushtivardhanam)...

The standard clinical technique for using repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD) is associated with limited efficacy to date. Such limited efficacy may be due to reliance on scalp-based targeting rather than state-of-the-science methods which incorporate fMRI-guided neuronavigation based on a specific model of neurocircuit dysfunction. In this review, we examine such a specific model drawn from regulatory focus theory, which postulates two brain/behavior systems, the promotion and prevention systems, underlying goal pursuit...
