Metachronous Pineal Germinoma 11 Years After Total Resection of a Mature Teratoma
Neuropathology, Volume 46, Issue 4, August 2026.ABSTRACT Central nervous system germ cell tumors are uncommon and include germinomas, teratomas, and other nongerminomatous germ cell tumors. Mature teratomas are usually cured by complete resection, but rare patients later develop a histologically distinct malignant germ cell tumor.

Rostrocaudal polarity formation of chick optic tectum [PDF]
, 1994 The optic tectum receives retinal fibers in a topographically ordered manner. For the formation of the precise connections, the tectum is believed to be positionally specified by gradients of molecules along axes.

New Phytologist, Volume 251, Issue 4, Page 2266-2283, August 2026.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Retinotectal projections influence optic tectum growth in zebrafish [PDF]
, 2015 In the zebrafish visual system, the retina and optic tectum grow in register throughout life. Both regions add new neurons from proliferation zones at their margins, with newly differentiated retinal ganglion cells projecting to, and making new synapses ...

Target selection by surgically misdirected optic fibers in the tectum of goldfish
, 1984 This study tested the capacity of regenerating optic fibers to read tectal markers and thereby grow to their appropriate tectal loci when initial position, optic pathway, and interfiber interactions are eliminated as useful cues.

Protocadherin 19 regulates axon guidance in the developing Xenopus retinotectal pathway
Molecular BrainProtocadherin 19 (Pcdh19) is a homophilic cell adhesion molecule and is involved in a variety of neuronal functions. Here, we tested whether Pcdh19 has a regulatory role in axon guidance using the developing Xenopus retinotectal system.

Diversity, 2020 The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints. Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D ...

An intrinsic CRF signaling pathway in the optic tectum [PDF]
, 2012 Corticotropin-releasing factor (CRF) is a 41 amino acid peptide that is best known as the principle hypophysiotropic hormone regulating the pituitary-adrenal axis during stress.

Nature Communications, 2016 Attention and gaze impact the spatial responsiveness of neurons in the optic tectum. Here the authors elucidate the mechanism by which cholinergic inputs affect receptive field properties of tectal neurons in a spatially precise manner in barn owls.
