Response of biological signals during acoustic and optical stimulation
Strakoš, Libor ; Chmelař, Milan (referee) ; Bubník, Karel (advisor)
The goal of this thesis is recording and evaluating of biological signals connected with autonomic nervous system. Changes in signals are caused by optical and acoustical stimuli. These stimuli are pictures of different meaning. Colors, basic symbols and neutral pictures with variance in colorization are included. Acoustic stimulation is provided by short startle stimulus of white noise sound impulse. Changes in signals are statistically and subjectively evaluated as changes in emotional state of tested person. Tested people fill in a questionnaire about their feelings. Results of signal processing and questionnaire are compared at the end.

Electric brain acticity changes during targeted emotional stimulation evaluated using sLORETA method
Špidlenová, Lada ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Name: Electrical cerebral activity changes during targeted emotional stimulation, evaluated by sLORETA Goals: The main goal of this thesis is the comparison of electrical brain activity changes during targeted emotional stimulation. Method: The research was conducted by measuring electrical cerebral activity using Natus Neurology 32-channel Nicolet™EEG Wireless Amplifier 32/64 device. The activity measurements were taken by an EEG Electro-cap with a total of 19 flat registration electrodes (Fp1, Fp2, F7, F3, Fz, F8, T5, T3, C3, Cz, C4, T4, T6, P3, Pz, 36 P4, O1, O2), placed in accord with the internationally used 10-20 system. The impendance resistance did not exceed 10 kΩ, with a sampling frequency of 512 Hz and a bandpass of 0,5-70 Hz. Resulting data was then processed using NeuroGuide programme. A 30s long, zero-artifact EEG section was then chosen to be exported to sLORETA programme. Probands were divided randomly into three research groups - positive, neutral and negative. Each proband was asked to pass the VVIQ imagination vividity questionnaire. In the next phase, each participant was asked to undergo a three week long imagination training programme, consisting of watching VR videos and targeted imaginations of walking, three times a week. While in the VR simulation, music and sound effect...

Individual Program for the Development of Visual Perception of Children with Visual Impairments Through LiteScout Boards and Accessories
KUČEROVÁ, Jana
This bachelor thesis deals with the development of visual perception of a visually impaired child using the LiteScout board and its accessories. The theoretical part of this work focuses on the characteristics of visual impairment, discusses the correction of the function of the affected organ, the development of unaffected senses and functions that replace the function of the affected vision and describes the methodology of developing visual perception so-called visual stimulation. The main part of the bachelor's thesis deals with the description of the diagnostic and intervention tool itself and the creation of an individual plan for the development of visual perception. The result of this bachelor's thesis is an individual plan with exercises tailored to a specific visually impaired child. Another result of this work is the translation of methodical materials for the LiteScout board, which is in the appendix of this work.

Support for visual perception in children with visual and multiple disabilitis
Adamčíková, Zdeňka ; Šumníková, Pavlína (advisor) ; Květoňová, Lea (referee)
This thesis focuses on functional assessments, visual stimulation and on offers of Centres for Early Intervention that provide services in the area of visual perception for children in early and preschool age. The goal of the thesis is to analyze interviews with workers in these centres on options and services in the area of visual aid that these centres provide for families and their children with disabilities. The first four chapters deal with theoretical background in the area of functional assessments of vision, visual stimulation and description of the group of children in early and preschool age with visual and multiple disabilities. Last but not least, these chapters also deal with organizations that provide early intervention services, their structure, composition of personnel and range of offered services. The content of the fifth chapter is a qualitative research investigation. The data were collected through interviews with instructors of visual stimulation and with an early intervention assistant. Analysis of these interviews then became basis for the subsequent definition of commendable suggestions for good practise.

Source analysis and comparation of Feldenkrais inspired movement and visual stimulation using sLORETA
Novotná, Tereza ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title of thesis: Source analysis and comparation of Feldenkrais inspired movement and visual stimulation using sLORETA Objectives: The thesis aim is to evaluate intracerebral source activity during a simple arm movement inspired by Feldenkrais method and to compare it with a visual stimulation of the same movement presented in a clip and with an imagination of the same movement. The movement inspired by Feldenkrais method was simplified to a repeated flexion of the dominant arm. Source analysis was evaluated from EEG and processed using sLORETA program, Methods: To obtain the data, experimental group was put together containing 12 participants aged 22-60, (mean = 27.2), both genders included. Participants were subjected to one-off measurement by the EEG instrument. Feldenkrais inspired movement of a flexion of a dominant upper right arm was investigated. The experiment constisted of six parts: 1. native EEG record with eyes closed and open, 2. active flexion of the dominant upper arm with eyes closed, 3. active flexion of the dominant upper arm with eyes opened, 4. watching video presenting repeated upper arm flexion, 5. dominant upper arm flexion imagination with eyes closed. Every part lasted for two minutes. Between individuals parts was inserted a pause. Obtained EEG data were processed with...

Visual Stimulation for Children with Severe Multiple Disabilities in Special Elementary School
HATWIKOVÁ, Lukania
The thesis examines visual stimulation for children with severe multiple disabilities in special elementary school. The aim of the thesis is to design, based on qualitative research, a re-education process of visual stimulation for children with severe multiple disabilities and its subsequent evaluation. In accord with the aims outlined above, two partial goals were formulated. The first goal was to determine the areas of visual perception in which the student struggles. The second goal was to assess the progress after visual stimulation. The thesis is divided into a theoretical and an empirical part. The theoretical part consists of three chapters. The first chapter defines terminology, the second one is devoted to education of pupils with multiple disabilities, and the third chapter describes visual stimulation, its rules, principles, and kinds. The empirical part characterizes the goals of the thesis, the methodology of research, and the technique used for gathering data. The qualitative method was used for the purposes of the empirical part. Data were gathered using observation, interview and document analysis. The re-education process was applied to respondents in order to support the impaired visual functions. The outcomes outlined in the empirical part will be applicable in the field of education of pupils with severe combined impairment. With some formal adjustments, these outcomes may serve as a starting point for preparing an insctructional and informational materiál for parents of children with severe multiple disabilities. The research discovered that no general conclusions can be drawn for work with children with this kind of impairment. Regular practice improves visual functions, but the current state of the child matters a lot. If the child is in bad mental or physical state, there might be regression.
