Age and gender alter synaptic proteins in zebrafish (Danio Rerio) models of normal and delayed aging
(Bilkent University, 2017-07)Cognitive decline occurs during normal aging in some specific domains of cognitive abilities including but not limited to episodic memory, divided attention and executive functions, however, it is not a unitary decline ... -
Age related alterations of adult neurogenesis and astrocytes in Zebrafish (Danio Rerio)
(Bilkent University, 2019-09)Brain aging is marked by a decline in cognitive abilities and associated with neurodegenerative disorders. In order to identify appropriate interventions to change the course of brain aging and age-related neurological ... -
Alterations in the molecular properties of neural stem cells from aged brains and brain tumors
(Bilkent University, 2017-06)It is known that new neuron formation in the brain continues throughout the life of an organism. In the adult human brain, it was proven that neurogenesis in the hippocampus is higher than expected, almost 700 new neurons ... -
Analysis of differentially expressed genes in bipolar disorder: transcriptomic signature of adolescence and young adulthood in working memory-relared area
(Bilkent University, 2020-11)Bipolar disorder (BD) is a heritable severe illness. One of the indications of BD is working memory (WM) impairment which is a heritable cognitive trait. The aim of the current study is to identify the transcriptomic ... -
Analysis of movement disorder-related genes following knockdowns of ANO10, WDR81, and VLDLR in zebrafish (DANIO RERIO)
(Bilkent University, 2018-06)Movement Disorders are the neurological symptoms that cause alterations in normal motility, posture and muscle tone. Certain brain areas, such as the cerebellum, mediate correct motor control and functioning. When defects ... -
Arithmetic and temporal transformations of working memory activation in subjects prone to psychosis
(Bilkent University, 2018-09)Working memory (WM) deficit is a well-studied cognitive impairment in psychosis which is stemming from various developmental abnormalities containing neurobiological heterogeneity. Recently, many studies have concluded ... -
Audiovisual interactions in time and spatial grouping principles of vision
(Bilkent University, 2016-10)Multisensory integration is often studied with intermodal con ict where either visual input dominates and alters the percept of simultaneous auditory input or the other way around. For instance, when put in con ict, visual ... -
Behavioral display of lumbar curvature in response to the opposite sex
(Bilkent University, 2017-06)The aim of this thesis was to investigate the hypothesis that women adjust their lumbar curvature to approach the suggested biomechanical optimum of 45.5 degrees in response to the presence of an attractive member of the ... -
Changes in FMRI resting state networks due to audiovisual association induced effects on visual motion perception
(Bilkent University, 2016-08)Associative learning, the process by which an association between two stimuli or a behavior and a stimulus is learned, is one of today's exciting and important topics of neuroscience. The in uence of multisensory ... -
Characterizing surround suppression in motion direction perception
(Bilkent University, 2021-06)Visual perception is often achieved by surround modulation mechanisms, which help us pool individual information in our visual field. This mechanism is also prominent in motion perception, namely motion discrimination. A ... -
Co-expression pairs and modules (CoEX-PM): a shiny application and an example case study on chromogranins
(Bilkent University, 2018-09)Gene expression signatures have been proved to be effective biomarkers of tumorigenesis and metastasis especially when alternative methods are inconvenient or ineffective. Nevertheless, handling very large datasets obtained ... -
Comparing the performance of humans and 3D-convolutional neural networks in material perception using dynamic cues
(Bilkent University, 2019-07)There are numerous studies on material perception in humans. Similarly, there are various deep neural network models that are trained to perform different visual tasks such as object recognition. However, the intersection ... -
Design and application of nerve growth factor-β binding peptide nanofibers for neural regeneration
(Bilkent University, 2016-11)Promotion of neurite outgrowth is an important limiting step for the regeneration of nerve injury and depends strongly on the local expression of nerve growth factor (NGF). Rational design of bioactive materials is a ... -
Development of bioactive peptide nanofibers for intervertebral disc regeneration
(Bilkent University, 2017-08)Lower back pain (LBP) and neck problems are the most common orthopedic diseases worldwide, and the main reason behind LBP is intervertebral disc degeneration (IVDD). Therefore, specialized therapeutic applications to induce ... -
Dynamic alternative splicing events in the dorsolateral prefrontal cortex during adolescence-young adulthood period and implications for schizophrenia
(Bilkent University, 2020-11)Alternative splicing (AS) or differential exon usage (DEU) is a regular process after gene expression and it contributes to the diversity of the genome by generating multiple protein isoforms. According to recent studies, ... -
EEG correlates of audiovisual associations in motion perception
(Bilkent University, 2018-12)The process of associative learning has been considered to be one of the promising research areas in neuroscience to understand human perception, sensory plasticity, and multisensory integration that affects the way of ... -
The effect of task on cue usefulness for visual scene classification
(Bilkent University, 2017-05)Detecting objects in the environment is one of the most fundamental functions of the visual system. Humans are highly effective at this, and past studies have shown that we can process things like whether or not an animal ... -
Effect of visual stimuli with fearful emotional cue on population receptive field estimates
(Bilkent University, 2019-07)Previous studies showed that the content of stimulus might affect the results of population receptive field (pRF) estimation method [1, 2, 3]. In addition, emotion might modulate visual processing in humans by increasing ... -
Effects of aging and short-term dietary restriction on neurogenesis and cellular senescence in the zebrafish (Danio Reio) brain
(Bilkent University, 2016-09)Currently we know from rodent and fish studies that adult neuron generation is reduced but still continues in old animals with a dynamic change throughout aging. This process occurs mainly in hippocampal region, which is ... -
Effects of aging on gene expression levels of inflammatory, cytoskeletal and microglial markers in the brain using the zebrafish (Danio Rerio) model organism
(Bilkent University, 2021-01)Age-related cognitive decline burdens the elderly population, limiting their abil-ity to socialize and be independent. To be able to develop proper treatments, healthy aging should be examined. Previous studies focusing ...
