  • the hypothesis that much or all of the information relayed by thalamus, even to classical, pure 'sensory' areas of cortex, represents a corollary message being sent simultaneously to motor centers. (elsevier.com)

  • neurons
  • The neurons in the so-called higher-order thalamus form the connecting lines between both areas of the brain. (eurekalert.org)
  • The processes in the neurons at the transition point between the thalamus and the cortex are particularly interesting for neuroscientists like Dr. Alexander Groh at the Institute of Neuroscience and the Department of Neurosurgery at TUM. (eurekalert.org)
  • cortical
  • Using the Rice-Vannucci model of neonatal hypoxic-ischemic brain injury, we have shown that neuronal degeneration in somatosensory thalamus is delayed in onset (∼24 hr) compared with cortical and striatal injury and exhibits prominent structural features of apoptosis. (jneurosci.org)

  • thalamic
  • A second RF is then built using the same feature vector, trained to provide a membership for each of the sic thalamic nuclear groups given that we know the thalamus from the first stage. (jhu.edu)
  • The thalamus comprises a system of lamellae (made up of myelinated fibers) separating different thalamic subparts. (wikipedia.org)
  • cortex
  • Groh and his team were able to show that the higher-order thalamus sends activating signals to the cortex. (eurekalert.org)
  • The brain can thus filter out important information in the thalamus and then forward this information in an amplified form and for a longer period of time to the cortex. (eurekalert.org)
  • structures
  • However, the degeneration of thalamus and other nonforebrain structures after hypoxia-ischemia is studied less frequently. (jneurosci.org)
  • These intensities provide clues about the boundary of the thalamus with non-thalamus structures. (jhu.edu)
  • These latter structures, different in structure from the major part of the thalamus, have been grouped together into the allothalamus as opposed to the isothalamus. (wikipedia.org)
  • significantly
  • Increased levels of Fas death receptor, Bax, and cytochrome c, activation of caspase 8, and abnormalities in mitochondria in the thalamus significantly precede the activation of caspase 3 and the appearance of neuronal apoptosis at 24 hr. (jneurosci.org)
  • nuclear
  • Segmentation and parcellation of the thalamus is an important step in providing volumetric assessment of the impact of disease weighted magnetic resonance (MR) images and nuclear parcellation using diffusion weighted MR images. (jhu.edu)
  • The RFs can be applied to a new subject, with classification scores determining the segmentation of the thalamus and subsequent parcellation of the nuclear groups. (jhu.edu)
  • Anterolateral region of the motor thalamus is a composite substructure of the ventral nuclear group of the thalamus based on connectivity and function. (wikipedia.org)
  • Brain
  • The thalamus is essentially the size of two walnuts and is located in the middle of the brain. (eurekalert.org)
  • Our first results compare our estimate of the thalamus with those from two whole brain segmentation software tools [1, (jhu.edu)
  • left
  • In order to reduce the computational burden of training an RF we estimate bounding boxes for the left and right thalami. (jhu.edu)

  • either
  • With 8-bit gaming being superseded by 16-bit gaming, production costs were rising, forcing hundreds of independent publishers, such as Thalamus, to either close down or allow themselves to be consumed by a publishing giant. (wikipedia.org)
  • role
  • Very little is still known about the role and the effects of this region, described as the higher-order thalamus. (eurekalert.org)

  • citation needed] The thalamus plays a major role in regulating arousal, the level of awareness, and activity. (wikipedia.org)
  • signals
  • The higher-order thalamus apparently serves to amplify important signals and also to store them temporarily over a certain period. (eurekalert.org)
  • memories
  • The researchers suggest that successful reactivation of memories depends on responses in the thalamus, which if activated feeds forward into the mediotemporal lobe, reinstating the memories and starting the consolidation process. (memory-key.com)
  • surface
  • The thalamus consists chiefly of gray substance, but its upper surface is covered by a layer of white substance, named the stratum zonale. (wikipedia.org)

  • name
  • Sanxion was the first release to bear the Thalamus name, and it garnered a Sizzler rating from Zzap!64 - this led to accusations of favouritism from rival publication Commodore User. (wikipedia.org)
  • Close
  • As the 1980s drew to a close, Thalamus continued to release C64 games, including the surreal puzzle/shooter Snare, the horizontal scroller Retrograde, from the Rowlands brothers and Heatseeker, a platform game with an environmental theme by Paul O'Malley. (wikipedia.org)
  • With their various Amiga projects spiraling out of budget and no further income, Thalamus had no choice but to close down their operations. (wikipedia.org)
