The octopus arm is a muscular hydrostat and due to its deformable and highly flexible structure it is capable of a rich repertoire of motor behaviors. Its motor control system uses planning principles and control strategies unique to muscular hydrostats. We previously reconstructed a data set of octopus arm movements from records of natural movements using(More)
Deposits that are recognized by antibodies specific for the C-terminal and beta-amyloid peptide (beta A) but not the N-terminal sequences of the amyloid precursor protein (APP) fragments are present in the extra- and intracellular space in ischemic rat brain with 1 year survival. The immunohistochemical profile indicates that the APP in these deposits is(More)
Tracking animal movements in 3D space is an essential part of many biomechanical studies. The most popular technique for human motion capture uses markers placed on the skin which are tracked by a dedicated system. However, this technique may be inadequate for tracking animal movements, especially when it is impossible to attach markers to the animal's body(More)
The paralytic tremor (pt) rabbit, a neurological mutant, exhibits hypomyelination transmitted in X-linked recessive fashion. This rabbit mutant was used for regional lipid analyses of different brain structures during development. There was a significant decrease of myelin-specific lipids, particularly in the cerebroside and sulfatide in pt rabbits. The(More)
Drivers' situation awareness is known to be remarkably low in the automated driving mode, which can result in a delayed and inefficient response when requested to resume control of the vehicle. The present study examined the usefulness of a haptic seat that projects spatial information on approaching vehicles to facilitate drivers' preparedness to take(More)
Immunostaining pattern of the temporal white matter with anti-tau-1 and anti-ubiquitin was different in examined cases of Alzheimer's disease (AD) and normal aging. Tau-1 immunoreactivity was observed in the white matter of all AD brains, in loosely dispersed neuropil threads (NT), a few neurofibrillary tangles (NFT) and scattered glial cells, whereas in(More)
The aim of the study was to compare ultrastructural brain changes in aging normal rabbits and in pt mutants with CNS hypomyelination. The study was performed on material of pt and healthy 3- and 4-year-old rabbits and on the control group of adult rabbits aged up to 2 years. Ultrastructural changes in both aging normal and pt rabbits included lipofuscin(More)
