[PDF] A detailed 3D MRI brain atlas of the African lungfish Protopterus annectens | Semantic Scholar (2024)

Analysis ofression patterns of Nkx2.1 and Islet-1 (Isl1), which encode transcription factors that are key in the regionalization of the forebrain, were analyzed by combined immunohistochemical methods in young adult specimens of two lungfishes and a urodele amphibian to get insights into the possible organization of theForebrain in the common ancestor of all tetrapods.

The detailed distribution of Pax6 cells in the adult central nervous system of lungfishes helps to understand the primitive condition that would have characterized the common ancestors to all sarcopterygians (lobe‐finned fishes and tetrapods), in which Pax6 would be needed to maintain specific entities of subpopulations of neurons.

Preoperative fMRI, in combination with MRI tractography and intraoperative DCS, may result in improved survival and extent of resection and reduced functional deficits and limited prospective evidence of its impact on patient outcomes is described.

The major scientific principles and recent clinical applications of brain MR elastography in diagnostic neuroscience are summarized and avenues for impact in assessing the pediatric brain are discussed.

The protein sequence analysis of SATB1 and SATB2 proteins and the immunolocalization of both, in combination with additional neuronal markers of highly conserved populations, in the brain of adult specimens of different bony fish models at key evolutionary points of vertebrate diversification revealed a high degree of conservation of both proteins.

Findings from the current study supported the use of 3T MRI as an adjunct diagnostic test for fish with suspected neurologic disease and provided a limited anatomic atlas of the teleost brain for use as a reference.

An MRI-based protocol and brain atlas are established to improve diagnostic capabilities in bearded dragons presenting with neurologic dysfunction and provides practitioners a neuroanatomic reference when performing brain MRI on the bearded dragon along with a concise and rapid MRI protocol.

It is found that the olfactory region appears to be more highly plastic than the hindbrain, and undergoes significant elongation in several taxa, while the semicircular canals covary as an integrated module, the utriculus and sacculus of the inner ear instead vary independently of each other.

Based on a consensus average 3D image generated from the MRIs of 13 male tawny dragon heads, a three-dimensional segmentation atlas is provided of the entire lizard brain that will facilitate numerous studies in evolutionary neuroscience.

A magnetic resonance imaging (MRI) atlas of the in vivo neuroanatomy of the juvenile axolotl brain is created, which is the first MRI atlas for this species and includes three levels: a division of the brain according to the embryological origin of the neural tube, and left and right hemispheres.
