Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)
The widely used blood oxygenation level dependent (BOLD) signal during brain activation,
as measured in typical fMRI methods, is composed of several distinct phases, the last
of which, and perhaps the least understood, is ...
A framework for integrating the songbird brain.
(J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2002-12)
Biological systems by default involve complex components with complex relationships.
To decipher how biological systems work, we assume that one needs to integrate information
over multiple levels of complexity. The songbird ...
Assessing visual requirements for social context-dependent activation of the songbird song system.
(Proc Biol Sci, 2009-01-22)
Social context has been shown to have a profound influence on brain activation in
a wide range of vertebrate species. Best studied in songbirds, when males sing undirected
song, the level of neural activity and expression ...
The neuropsychology of autobiographical memory.
(Cortex, 2003-09)
This special issue of Cortex focuses on the relative contribution of different neural
networks to memory and the interaction of 'core' memory processes with other cognitive
processes. In this article, we examine ...
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)
Movements are necessary to engage the world, but every movement results in sensorimotor
ambiguity. Self-movements cause changes to sensory inflow as well as changes in the
positions of objects relative to motor effectors ...
Songbirds and the revised avian brain nomenclature.
(Ann N Y Acad Sci, 2004-06)
It has become increasingly clear that the standard nomenclature for many telencephalic
and related brainstem structures of the avian brain is based on flawed once-held assumptions
of homology to mammalian brain structures, ...
Microcircuits for attention.
(Neuron, 2007-07-05)
Researchers who study the neuronal basis of cognition face a paradox. If they extract
the brain, its cognitive functions cannot be assessed. On the other hand, the brain's
microcircuits are difficult to study in the intact ...
A relationship between behavior, neurotrophin expression, and new neuron survival.
(Proc Natl Acad Sci U S A, 2000-07-18)
The high vocal center (HVC) controls song production in songbirds and sends a projection
to the robust nucleus of the archistriatum (RA) of the descending vocal pathway. HVC
receives new neurons in adulthood. Most of the ...
Learned birdsong and the neurobiology of human language.
(Ann N Y Acad Sci, 2004-06)
Vocal learning, the substrate for human language, is a rare trait found to date in
only three distantly related groups of mammals (humans, bats, and cetaceans) and three
distantly related groups of birds (parrots, hummingbirds, ...
The short and long of it: neural correlates of temporal-order memory for autobiographical events.
(J Cogn Neurosci, 2008-07)
Previous functional neuroimaging studies of temporal-order memory have investigated
memory for laboratory stimuli that are causally unrelated and poor in sensory detail.
In contrast, the present functional magnetic resonance ...
