Developing oocytes of the cnidarian Bunodosoma cavernata are located within the mesoglea of the mesenteries of the gastrovascular cavity. The cortex of the more mature vitellogenic oocytes contains numerous, electron-dense, membrane-bound, cortical granules. The surface of these oocytes possesses prominent radially projecting structures termed cytospines. Each cytospine has a core of microfilam...

Mechanical perturbations applied to the wrist joint typically evoke a stereotypical sequence of cortical and muscle responses. The early cortical responses (<100 ms) are thought be involved in the "rapid" transcortical reaction to the perturbation while the late cortical responses (>100 ms) are related to the "slow" transcortical reaction. Although previous studies indicated that both responses...

Oscillations in local field potentials in the beta-frequency band (13-35 Hz) are a pervasive feature of human and nonhuman primate motor cortical areas. However, the function of such synchronous activity across populations of neurons remains unknown. Here, we test the hypothesis that beta activity may promote existing motor set and posture while compromising processing related to new movements....

Notwithstanding the apparent demands regarding fine motor skills that are required to perform in action video games, nervous system of players has not been studied systematically. In present study, we hypothesized find differences sensorimotor performance and corticospinal characteristics between game (Players) Controls. We tested games tasks used transcranial magnetic stimulation (TMS) measure...

background: in vitro model studies are becoming increasingly popular for experimental research designs. they include isolation and expansion of cells of a particular tissue, such as the nervous tissue which contributes to understanding the underlying mechanisms in many pathologies. it enables  the scrutinization of intracellular signaling pathways responsible for cell death. objectives: in the ...

cortical spreading depression (csd) has been suggested to underlie some neurological disorders such as migraine. despite the intensity with which many investigators have studied sd in the brain, only a few studies have aimed to identify sd in the spinal cord. here we described the main characteristic features of sd in the spinal cord induced by different methods including various spinal cord in...

abstract seizure disorders are the most common neurological illnesses in infants and children. presented is an 8 year old boy with nocturnal vomiting episodes, found to have eeg characteristics of early onset benign occipital epilepsy, better known as panayiotopoulos syndrome.
