Lorcaserin Alters Serotonin and Noradrenaline Tissue Content and Their Interaction With Dopamine in the Rat Brain

open access: yesFrontiers in Pharmacology, 2020
Lorcaserin is a preferential serotonin2C receptor (5-HT2CR) agonist effective to treat obesity that has also recently been proposed to treat addiction and epilepsy.

Distributed hierarchical processing in the primate cerebral cortex.

open access: yesCerebral Cortex, 1991
In recent years, many new cortical areas have been identified in the macaque monkey. The number of identified connections between areas has increased even more dramatically.

Speech rhythms and multiplexed oscillatory sensory coding in the human brain [PDF]

open access: yes, 2013
Cortical oscillations are likely candidates for segmentation and coding of continuous speech. Here, we monitored continuous speech processing with magnetoencephalography (MEG) to unravel the principles of speech segmentation and coding.

The Fusiform Face Area: A Module in Human Extrastriate Cortex Specialized for Face Perception

open access: yesJournal of Neuroscience, 1997
Using functional magnetic resonance imaging (fMRI), we found an area in the fusiform gyrus in 12 of the 15 subjects tested that was significantly more active when the subjects viewed faces than when they viewed assorted common objects.

Elastic instabilities in a layered cerebral cortex: A revised axonal tension model for cortex folding [PDF]

open access: yesNew Journal of Physics 16, 123058 (2014), 2014
We model the elasticity of the cerebral cortex as a layered material with bending energy along the layers and elastic energy between them in both planar and polar geometries. The cortex is also subjected to axons pulling from the underlying white matter.

Co-transmission of acetylcholine and GABA regulates hippocampal states

open access: yesNature Communications, 2018
Acetylcholine (ACh) release in the central nervous system is thought to be unitary and mediated non-synaptically in volume transmission. Here, Takács and colleagues show cholinergic terminals juxtapose GABAergic synapses anatomically and functionally ...

Cellular resolution circuit mapping with temporal-focused excitation of soma-targeted channelrhodopsin

open access: yeseLife, 2016
We describe refinements in optogenetic methods for circuit mapping that enable measurements of functional synaptic connectivity with single-neuron resolution.

Attention-dependent modulation of cortical taste circuits revealed by granger causality with signal-dependent noise [PDF]

open access: yes, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

«Chimera principle»: qualitative analysis of psychophysiological isomorphism of persons with identity integration disorder

open access: yesОбозрение психиатрии и медицинской психологии имени В.М. Бехтерева, 2018
In the article, using the example of the «identity integration disorder», the author’s conceptual framework, the application of the theory of psychophysiological isomorphism that originated in the framework of classical gestaltpsychology to the modern ...

The topology of connections between rat prefrontal and temporal cortices [PDF]

open access: yes, 2015
Understanding the structural organization of the prefrontal cortex (PFC) is an important step toward determining its functional organization. Here we investigated the organization of PFC using different neuronal tracers.
