Papers for the month of August 2013


"Impact of neuronal heterogeneity on correlated colored noise-induced synchronization"
Frontiers in Computational Neuroscience, 0:0

Mouse over here for a brief summary or click to open article in a new tab.We compute the phase-difference density for a pair of heterogeneous oscillators receiving correlated colored noise. We compare the theory to simulations and to data recorded from the mouse olfactory bulb.


"A disinhibitory microcircuit initiates critical-period plasticity in the visual cortex"
Nature, 000:000

Mouse over here for a brief summary or click to open article in a new tab.The structure and function of our brain is readily changed by life experiences, and these changes are most profound during so-called critical periods of childhood development. Why do the young seem to acquire new skills so effortlessly compared to adults? Here we identify the specific biological circuit that initiates critical period learning in the young and is absent in adults.


"3D reconstruction of 2D fluorescence histology images and registration with in vivo MR images: Application in a rodent stroke model."
Journal of Neuroscience Methods, 219:27-40

Mouse over here for a brief summary or click to open article in a new tab.This paper describes the generation of 3D reconstructions of whole rat brains from immunohistochemically stained sections and their co-registration with MR images to interrogate the neurological basis of signal changes in stroke at the voxel level


"The late response of rat subependymal zone stem and progenitor cells to stroke is restricted to directly affected areas of their niche."
Experimental Neurology, 248:387-397

Mouse over here for a brief summary or click to open article in a new tab.This paper describes the sub-actue and chronic endogenous response of neural stem cells in the sub-ependymal zone in the brain to stroke damage.


"Aberrant Crossed Corticospinal Facilitation in Muscles Distant from a Spinal Cord Injury"
PLoS One, August, 2013 in press:in press

Mouse over here for a brief summary or click to open article in a new tab.Crossed facilitatory interactions in the corticospinal pathway are impaired in humans with chronic spinal cord injury (SCI). The extent to which crossed facilitation is affected in muscles above and below the injury remains unknown. Our results support the view that corticospinal degeneration does not spread rostral to the lesion, and highlights the potential of caudal regions distant from an injury to facilitate residual corticospinal output after SCI.


"Pattern recognition on anterior cingulate cortex blood flow classified depressed females with bipolar vs. unipolar depression. "
British Journal of Psychiatry, 0:0

Mouse over here for a brief summary or click to open article in a new tab.Differentiating bipolar from recurrent unipolar depression is a major clinical challenge. In 18 healthy females and 36 females in a depressive episode – 18 with bipolar disorder type I, 18 with recurrent unipolar depression – we applied pattern recognition analysis using subdivisions of anterior cingulate cortex (ACC) blood flow at rest, measured with arterial spin labelling. Subgenual ACC blood flow classified unipolar v. bipolar depression with 81% accuracy (83% sensitivity, 78% specificity).


"Can singular examples change implicit racial attitudes in the real-world?"
Frontiers in Perception Science, 4:594

Mouse over here for a brief summary or click to open article in a new tab.We present evidence that the 2008 US election may have facilitated at least a temporary change in implicit racial attitudes in the US. Our results rely on the Affective Lexical Priming Score or “ALPS” and pre- and post-election measurements for both US and non-US participants. US students who, pre-election, exhibited negative associations with black faces, post-election showed positive associations with black faces. Canadian students pre- and post-election did not show a similar shift.
