CA1-projecting subiculum neurons facilitate object-place learning. [PDF]

open access: yes, 2019
Recent anatomical evidence suggests a functionally significant back-projection pathway from the subiculum to the CA1. Here we show that the afferent circuitry of CA1-projecting subicular neurons is biased by inputs from CA1 inhibitory neurons and the ...

Mechanisms of spindle positioning. [PDF]

open access: yes, 2013
Accurate positioning of spindles is essential for asymmetric mitotic and meiotic cell divisions that are crucial for animal development and oocyte maturation, respectively.

A Novel CHMP2B Splicing Variant in Atypical Presentation of Familial Frontotemporal Lobar Degeneration

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT C‐truncating variants in the charged multivesicular body protein 2B (CHMP2B) gene are a rare cause of frontotemporal lobar degeneration (FTLD), previously identified only in Denmark, Belgium, and China. We report a novel CHMP2B splice‐site variant (c.35‐1G>A) associated with familial FTLD in Spain. The cases were two monozygotic male twins who

Magnetic ressonance imaging in the diagnosis of Creutzfeldt-Jakob disease: report of two cases

open access: yesDementia & Neuropsychologia
Creutzfeldt-Jacob disease (CJD) is a rare condition caused by a pathogenic prion protein that evolves with rapidly progressive dementia and death. The clinical presentation may sometimes be misleading. Magnetic Resonance Imaging (MRI) aids diagnosis with

Odor identity coding by distributed ensembles of neurons in the mouse olfactory cortex

open access: yeseLife, 2017
Olfactory perception and behaviors critically depend on the ability to identify an odor across a wide range of concentrations. Here, we use calcium imaging to determine how odor identity is encoded in olfactory cortex.

VIP interneurons in mouse primary visual cortex selectively enhance responses to weak but specific stimuli

open access: yeseLife, 2020
Vasoactive intestinal peptide-expressing (VIP) interneurons in the cortex regulate feedback inhibition of pyramidal neurons through suppression of somatostatin-expressing (SST) interneurons and, reciprocally, SST neurons inhibit VIP neurons. Although VIP

Alterations of the giant pyramidal neurons (Betz cells) in brain cortex of rat offspring born from gestational diabetic dams: A morphometric study [Alteraciones de las Neuronas Piramidales Gigantes de la Corteza Cerebral en Crías de Ratas Nacidas de Hembras con Diabetes Gestacional: Un Estudio Morfométrico] [PDF]

open access: yes, 2015
A few studies reported the adverse effects of gestational diabetes on hippocampus and spinal cord of rat offspring. Giant pyramidal neurons are giant pyramidal neurons located in fifth layers of the gray matter in the primary motor cortex.

Diagnostic Challenge in Frontal Variant Alzheimer's Disease With Low Amyloid‐β PET Retention

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diagnosing frontal variant Alzheimer's disease (fvAD) is difficult and could be even more difficult when amyloid‐beta (Aβ) PET retention is low. A 63‐year‐old woman presenting with a 3‐year history of apathy and memory impairment showed executive dysfunction, memory impairment, and severe bilateral frontotemporal atrophy on MRI.

Distinct causal influences of parietal versus frontal areas on human visual cortex: evidence from concurrent TMS-fMRI [PDF]

open access: yes, 2010
It has often been proposed that regions of the human parietal and/or frontal lobe may modulate activity in visual cortex, for example, during selective attention or saccade preparation.

Reading the mind's eye: Decoding category information during mental imagery [PDF]

open access: yes, 2009
Category information for visually presented objects can be read out from multi-voxel patterns of fMRI activity in ventral–temporal cortex. What is the nature and reliability of these patterns in the absence of any bottom–up visual input, for example ...
