Functional anatomy of macaque striate cortex. V. Spatial frequency [PDF]

open access: yesThe Journal of Neuroscience, 1988
When macaque monkeys view achromatic, sinusoidal gratings of a single spatial frequency, the pattern of 14C-2-deoxy-d-glucose (DG) uptake produced by the gratings is shown to depend on the spatial frequency chosen. When a relatively high (5–7 cycles/deg) spatial frequency is shown binocularly at systematically varied orientations, uptake in parafoveal ...

A perspective on cortical layering and layer-spanning neuronal elements [PDF]

open access: yes, 2018
This review article addresses the function of the layers of the cerebral cortex. We develop the perspective that cortical layering needs to be understood in terms of its functional anatomy, i.e., the terminations of synaptic inputs on distinct cellular ...

Abnormal Changes of Brain Cortical Anatomy and the Association with Plasma MicroRNA107 Level in Amnestic Mild Cognitive Impairment

open access: yesFrontiers in Aging Neuroscience, 2016
MicroRNA107 (Mir107) has been thought to relate to the brain structure phenotype of Alzheimer’s disease. In this study, we evaluated the cortical anatomy in amnestic mild cognitive impairment (aMCI) and the relation between cortical anatomy and plasma ...

Patterns of Individual Variation in Visual Pathway Structure and Function in the Sighted and Blind. [PDF]

open access: yesPLoS ONE, 2016
Many structural and functional brain alterations accompany blindness, with substantial individual variation in these effects. In normally sighted people, there is correlated individual variation in some visual pathway structures.

Age of second language acquisition affects nonverbal conflict processing in children : an fMRI study [PDF]

open access: yes, 2014
Background: In their daily communication, bilinguals switch between two languages, a process that involves the selection of a target language and minimization of interference from a nontarget language. Previous studies have uncovered the neural structure

Functional anatomy of macaque striate cortex. II. Retinotopic organization [PDF]

open access: yesThe Journal of Neuroscience, 1988
Macaque monkeys were shown retinotopically-specific visual stimuli during 14C-2-deoxy-d-glucose (DG) infusion in a study of the retinotopic organization of primary visual cortex (V1). In the central half of V1, the cortical magnification was found to be greater along the vertical than along the horizontal meridian, and overall magnification factors ...

Rhizome and root anatomy of 14 species of Bromeliaceae

open access: yesRodriguésia
The anatomy of rhizomes and roots of 14 species of Bromeliaceae that occur in the cerrado biome were studied with the aim of pointing out particular anatomical features of the family and possible adaptations related to the environment.

Is There a Canonical Cortical Circuit for the Cholinergic System? Anatomical Differences Across Common Model Systems

open access: yesFrontiers in Neural Circuits, 2018
Acetylcholine (ACh) is believed to act as a neuromodulator in cortical circuits that support cognition, specifically in processes including learning, memory consolidation, vigilance, arousal and attention. The cholinergic modulation of cortical processes

Why musical memory can be preserved in advanced Alzheimer's disease [PDF]

open access: yes, 2015
Musical memory is relatively preserved in Alzheimer's disease and other dementias. In a 7 Tesla functional MRI study employing multi-voxel pattern analysis, Jacobsen et al.
