11. Neuronal mechanisms of feedback postural control
Abstract : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. READ MORE

12. Activity-regulated retinoic acid signaling in olfactory sensory neurons
Abstract : The aim of the studies included in the thesis is to better understand the interplay between neuronal activity-dependent gene regulation and the bioactive vitamin A metabolite all-trans-retinoic acid (RA) during postnatal development, refinement and maintenance of precise neuronal connectivity using the olfactory sensory neuron (OSN) in the olfactory epithelium (OE) of genetically modified mice as a model. We show that:Inhibition of RA receptor (RAR)-mediated transcription in OSNs reduces expression of the olfactory cyclic nucleotide-gated (CNG) ion channel, which is required for odorant receptor (OR)-mediated stimulus transduction.

13. Phenomenological modelling of sensory integration phenomena using self-organized feature maps
Abstract : The main contribution of the work presented herein is a method of transferring information from one lattice of artificial neural units to another. The essence of the present method consists of four parts: (1) the wrapping of the artificial neural lattice into a module that given an input to this lattice outputs normalized coordinates for the location of peak activity and the magnitude of the activity at that location; (2) the inter-module exchange of information being carried out by using the coordinates of the neuron that respond the strongest to the input given to the artificial neural lattice; (3) the concept of the transformation map which re-maps normalized coordinates from one module's output space on another's; and (4) fusion carried out by summation of activity fields induced by artificial neural lattices.

14. Effects of acute alcohol intoxication on human sensory orientation and postural control
Abstract : Alcohol affects balance and is related to falls and injuries. Even though alcohol effects on balance and eye movement have been studied before we know less about the dose and time dependent effects and how each supportive sense to balance contributes during acute alcohol intoxication.

15. Sensory impairment of the upper limb after stroke: influence on daily life and effects of a novel training approach
Abstract : Abstract: Sensory impairments in the upper limb are common after stroke. Different sensory modalities can be affected such as sense of touch, pressure, pain, temperature and proprioception. The sensory impairments can negatively affect motor function, dexterity and the ability to perform daily activities. READ MORE
