Block-interleaved segmented echo-planar imaging for improved activity detection in submillimeter high-resolution functional MRI at 7 T. [PDF]
Magn Reson MedAbstract Purpose Isotropic submillimeter high‐resolution functional MRI (fMRI) facilitates noninvasive investigation of neuronal activities at the mesoscale level, including cortical columns and laminae. However, the task‐evoked functional activity becomes less detectable when using single‐shot echo planar imaging (EPI) with parallel imaging techniques

Anatomical Progression of Neuropathology in FTLD‐TDP Type C and Linkage to Annexin A11
Annals of Neurology, EarlyView.Objective Frontotemporal lobar degenerations (FTLD)‐TDP type C (TDP‐C) is distinguished from other FTLD‐TDP subtypes by 3 unique features: (1) invariable onset in the anterior temporal lobe (ATL), (2) phosphorylated TDP‐43 (pTDP) neurites in cortex, and (3) colocalization of all pTDP deposits with annexin A11 (ANXA11).

Linking the Laminar Circuits of Visual Cortex to Visual Perception [PDF]
, 2001 A detailed neural model is being developed of how the laminar circuits of visual cortical areas V1 and V2 implement context-sensitive binding processes such as perceptual grouping and attention, and develop and learn in a stable way.

Bioprinted Excitable Tissues with Multistimulation Systems for Promoting Function and Maturation
Advanced NanoBiomed Research, EarlyView.This review provides an overview of stimulation strategies used to enhance the functional maturation of bioprinted excitable tissues. It addresses key limitations in physiological performance of bioprinted excitable tissues, outlines major stimulation modalities—including electrical, mechanical, optical, magnetic, ultrasound, and hybrid—and examines ...

Functional blindsight and its diagnosis
Frontiers in NeurologyEven when brain scans fail to detect a striate lesion, functional evidence for blindsight can be adduced. In the aftermath of an automobile accident, JK became blind. Results of ophthalmic exams indicated that the blindness must be cortical. Nevertheless,

The Anatomical Record, EarlyView.Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

A Simple Cell Model with Multiple Spatial Frequency Selectivity and Linear/Non-Linear Response Properties [PDF]
, 1994 A model is described for cortical simple cells. Simple cells are selective for local contrast polarity, signaling light-dark and dark-light transitions. The proposed new architecture exhibits both linear and non-linear properties of simple cells.

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Heidenhain variant of Creutzfeldt-Jakob disease: An autopsy study from India
Annals of Indian Academy of Neurology, 2009 Prion diseases are rare, progressive and fatal neurodegenerative diseases characterized by long incubation period and short clinical course. We present a rare case of Heidenhain variant of Creutzfeldt-Jakob disease, occurring in a 55-year-old lady ...
