Direction- and distance-dependent interareal connectivity of pyramidal cell subpopulations in the rat frontal cortex

open access: yesFrontiers in Neural Circuits, 2013
The frontal cortex plays an important role in the initiation and execution of movements via widespread projections to various cortical and subcortical areas.

A Connectome-Based, Corticothalamic Model of State- and Stimulation-Dependent Modulation of Rhythmic Neural Activity and Connectivity

open access: yesFrontiers in Computational Neuroscience, 2020
Rhythmic activity in the brain fluctuates with behaviour and cognitive state, through a combination of coexisting and interacting frequencies. At large spatial scales such as those studied in human M/EEG, measured oscillatory dynamics are believed to ...

Corticofugal Gating of Auditory Information in the Thalamus: An In Vivo Intracellular Recording Study [PDF]

open access: yes, 2004
In the present study, we investigated the auditory responses of the medial geniculate (MGB) neurons, through in vivo intracellular recordings of anesthetized guinea pigs, while the auditory cortex was electrically activated.

A mechanism for deviance detection and contextual routing in the thalamus: a review and theoretical proposal

open access: yesFrontiers in Neuroscience
Predictive processing theories conceptualize neocortical feedback as conveying expectations and contextual attention signals derived from internal cortical models, playing an essential role in the perception and interpretation of sensory information ...

The efficacy of transcranial current stimulation techniques to modulate resting-state EEG, to affect vigilance and to promote sleepiness [PDF]

open access: yes, 2018
Transcranial Current Stimulations (tCSs) are non-invasive brain stimulation techniques which modulate cortical excitability and spontaneous brain activity by the application of weak electric currents through the scalp, in a safe, economic, and well ...

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Posterior medial corticothalamic connectivity and consciousness [PDF]

open access: yesAnnals of Neurology, 2012
In a foundational study published in this issue of Annals of Neurology, Fernandez-Espejo et al1 report that diagnostic categories of disorders of consciousness can be stratified by diffusion tensor imaging (DTI) of connections among specific components of the default-mode network (DMN).2 The DMN includes the corticocortical and thalamocortical ...

Thalamic Circuit Diversity: Modulation of the Driver/Modulator Framework

open access: yesFrontiers in Neural Circuits, 2016
The idea that dorsal thalamic inputs can be divided into drivers, which provide the primary excitatory drive for the relay of information to cortex, and modulators, which alter the gain of signal transmission, has provided a valuable organizing principle

An in vivo intracellular study of auditory thalamic neurons [PDF]

open access: yes, 2003
The intrinsic electrophysiological properties of medial geniculate body (MGB) neurons and their responses to noise bursts/pure tones were examined in the pentobarbital anesthetized guinea pig through intracellular recording. Discharge rate was calculated

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges

open access: yesEpilepsia Open, EarlyView.
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across
