Circuit Reorganization of Subicular Cell-Type-Specific Interneurons in Temporal Lobe Epilepsy

The subiculum represents a crucial brain pivot in regulating seizure generalization in temporal lobe epilepsy (TLE), primarily through a synergy of local GABAergic and long-projecting glutamatergic signaling. However, little is known about how subicular GABAergic interneurons are involved in a cell-type–specific way. Here, employing Ca2+ fiber photometry, retrograde monosynaptic viral tracing, and chemogenetics in epilepsy… Continue reading Circuit Reorganization of Subicular Cell-Type-Specific Interneurons in Temporal Lobe Epilepsy

Multivariate Pattern Analysis of EEG Reveals Neural Mechanism of Naturalistic Target Processing in Attentional Blink

The human brain has inherent limitations in consciously processing visual information. When individuals monitor a rapid sequence of images for detecting two targets, they often miss the second target (T2) if it appears within a short time frame of 200–500 ms after the first target (T1), a phenomenon known as the attentional blink (AB). The… Continue reading Multivariate Pattern Analysis of EEG Reveals Neural Mechanism of Naturalistic Target Processing in Attentional Blink

Oscillatory Brain Activity in the Canonical Alpha-Band Conceals Distinct Mechanisms in Attention

Brain oscillations in the alpha-band (8–14 Hz) have been linked to specific processes in attention and perception. In particular, decreases in posterior alpha-amplitude are thought to reflect activation of perceptually relevant brain areas for target engagement, while alpha-amplitude increases have been associated with inhibition for distractor suppression. Traditionally, these alpha-changes have been viewed as two facets… Continue reading Oscillatory Brain Activity in the Canonical Alpha-Band Conceals Distinct Mechanisms in Attention

Intracranial Voltage Profiles from Untangled Human Deep Sources Reveal Multisource Composition and Source Allocation Bias

Intracranial potentials are used as functional biomarkers of neural networks. As potentials spread away from the source populations, they become mixed in the recordings. In humans, interindividual differences in the gyral architecture of the cortex pose an additional challenge, as functional areas vary in location and extent. We used source separation techniques to disentangle mixing… Continue reading Intracranial Voltage Profiles from Untangled Human Deep Sources Reveal Multisource Composition and Source Allocation Bias
