Data Analysis and Clasification from the Brain Activity Detector
Jileček, Jan ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
This thesis aims to implement methods for recording EEG data obtained with the neural activity sensor OpenBCI Ultracortex IV headset. It also describes neurofeedback, methods of obtaining data from the motor cortex for further analysis and takes a look at the machine learning algorithms best suited for the presented problem. Multiple training and testing datasets are created, as well as a tool for recording the brain activity of a headset-wearing test subject, which is being visually presented with cognitive challenges on the screen in front of him. A neurofeedback demo app has been developed, presented and later used for calibration of new test subjects. Next part is data analysis, which aims to discriminate the left and right hand movement intention signatures in the brain motor cortex. Multiple classification methods are used and their utility reviewed.

EEG Biofeedback Human Brain - Computer Interface
Kněžík, Jan ; Kořenek, Jan (referee) ; Marušinec, Jaromír (advisor)
This master thesis dwells on EEGbiofeedback (also called Neurofeedback) interface of human brain and the computer and its concrete realization in Java programming language. This system is founded on the basis of the computer, which is accomplishing biological feedback (biofeedback) and the electroencephalography (EEG) by helping that state's scanning of user's brain is realized. By this way is possible to practise the human brain effectively to achieve better concentration, the elimination of sleeping and learning deficiency. Hereafter is the suggestion of direction control of computer mouse by EEG device incorporated, which makes it possible for the man to regulate the direction of the cursor's movement on the screen by the frequency of brain's oscillation. The motivation for solution of this problem is the effort to help to handicapped people to communicate with surrounding world. The introduction of this paper contains the basic facts about human brain, electroencephalography and EEG biofeedback. The following chapters dwell on the specification of claims to developed application, its suggestion and description of actual realization. The final part relates to the BCI (Brain-Computer Interface) systems and suggestion of computer's control by EEGappliance with evaluation of attained results.

Neurotraining in tennis
Gavendová, Karolína ; Kočíb, Tomáš (advisor) ; Hráský, Pavel (referee)
Title: Neuro-athletic training in tennis Objectives: The bachelor thesis is divided into two parts. The first part is theoretical and its aim is to inform about neuro-athletic training and the possibilities of including this training in the tennis preparation of players of different age categories. At the same time, the theoretical part also provides a basic overview of the central nervous system and sensory systems on which neuro-athletic training is built. The goal of the second part is to create a stack of exercises that neuro-athletic training uses for tennis players of different age categories. The set of exercises will be divided into four sections - evaluation of training results, general exercises for visual, vestibular and proprioceptive training, neuro-athletic exercises for speed development, neuro-athletic exercises for strength development. Methods: In the theoretical part, we analyzed literature, internet resources and videos dealing with the topic of neuro-athletic training. Based on the analysis, we synthesized the individual findings in order to create a clear information base on the physiological aspects of tennis, the central nervous system and sensory senses, neuro-athletic training. Based on this information, we selected suitable neuro- athletic exercises and created a stack of...

Cognitive and behavioral alterations in neurodevelopmental and pharmacological animal models of schizophrenia
Malenínská, Kristýna ; Stuchlík, Aleš (advisor) ; Blahna, Karel (referee) ; Telenský, Petr (referee)
Establishing reliable animal models of psychiatric diseases such as schizophrenia is essential to better understand the neurobiological, behavioural and genetic basis of the disorder and to develop new drugs with greater therapeutic efficacy. These models allow the study of different aspects of schizophrenia, including positive, negative and cognitive symptoms similar to schizophrenia. All available animal models of schizophrenia can be divided into four different categories of induction: developmental, pharmacological, genetic and lesion-induced. However, none of these models perfectly replicates all aspects of schizophrenia in humans, and it is therefore necessary to precisely define the influence of each manipulation. This thesis focuses on the study of pharmacological and developmental animal models of schizophrenia, with an emphasis on examining the cognitive and behavioral changes associated with the disorder. Specifically, we investigated the pharmacological induction of schizophrenia- like symptoms by acute administration of MK-801, developmental models of two interventions combining the maternal immune response following poly(I:C) administration and subsequent stress of offspring in adolescence, and repeated prenatal and neonatal administration of lipopolysaccharide (LPS). In the...

Disorders of brain energy metabolism in Alzheimer's and Parkinson's disease
Řezáčová, Adéla ; Telenský, Petr (advisor) ; Kolář, David (referee)
Alzheimer's and Parkinson's diseases belong to group of neurodegenerative diseases that affect not only the patients, but also their surroundings. Patients of those diseases gradually lose their neurons. Both disorders are typical for pathophysiological accumulation of proteins which affect the functioning of neurons and astrocytes. These disorders are also characterised by mitochondrial senescence and its damages which itself manifest by dysfunction of various complexes. Furthermore, in both diseases, there can be found insulin resistance, which leads to an insufficient insulin signalization. Both diseases are also accompanied by impaired metabolisms of amino acids. With Alzheimer's disease, there is significantly lowered metabolism of glucose, whereas with Parkinson's disease, there is not enough stimulation for action potential to proceed in dopaminergic neurons in substantia nigra. These impairments in Alzheimer's disease cause cognitive dysfunction, while with Parkinson's disease, these defects predominantly lead to complications with motor function. By studying energetic changes in presented diseases could bring more effective treatment.
