Intracranial electroencephalography reveals effector-independent evidence accumulation dynamics in multiple human brain regions

Academic News Report: Revealing Effector-Independent Evidence Accumulation Dynamics from Intracranial Electrophysiological Recordings Research Background The neural mechanisms underlying the decision-making process have long been a significant topic in neuroscience. Previous studies have indicated that it is possible to identify neural signals rela...

Information-Based TMS to Mid-Lateral Prefrontal Cortex Disrupts Action Goals During Emotional Processing

Abstract In recent years, researchers have gradually recognized that contextual awareness and goal-directed responses to emotional events are crucial for adaptive functioning. Behavioral and emotional regulation models posit that the lateral prefrontal cortex (lpfc) maintains goal-related representations, thereby facilitating cognitive control. How...

Low-Intensity Ultrasound Ameliorates Brain Organoid Integration and Rescues Microcephaly Deficits

Low-intensity Ultrasound Promotes Brain Organoid Integration and Improves Microcephaly Defects Background of the Study Brain organoids are generated through the differentiation of pluripotent stem cells (PSCs) and exhibit impressive cellular diversity, capable of mimicking functional networks similar to the human brain. These organoid methods hold ...

Mapping Interictal Discharges Using Intracranial EEG-fMRI to Predict Postsurgical Outcomes

Mapping Interictal Discharges Using Intracranial EEG-fMRI to Predict Postsurgical Outcomes

Using Intracranial EEG-fMRI Mapping of Intermittent Discharges to Predict Epilepsy Surgery Outcomes Background and Objective Epilepsy is a common neurological disorder, and many patients are unresponsive to pharmacological treatments, making surgery one of the primary therapeutic options. However, accurately localizing the seizure onset zone (SOZ) ...

Distinct Virtual Histology of Grey Matter Atrophy in Four Neuroinflammatory Diseases

Research Background The core focus of this study is the manifestation of gray matter atrophy in neuroinflammatory diseases. Gray matter atrophy typically appears in four types of neuroinflammatory demyelinating diseases: Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorders (NMOSD) positive (AQP4+) and negative (AQP4-) for aquaporin-4 an...

DeepDTI: High-Fidelity Six-Direction Diffusion Tensor Imaging Using Deep Learning Research Background and Motivation Diffusion Tensor Imaging (DTI) boasts unparalleled advantages in mapping the microstructure and structural connectivity of live human brain tissue. However, traditional DTI techniques require extensive angular sampling, leading to pr...

Scalp nerve block alleviates headaches associated with sonication during transcranial magnetic resonance–guided focused ultrasound

In this academic paper, the authors attempt to address the common headache complication during magnetic resonance-guided focused ultrasound (mrgFUS) treatment. Headache is a common complication, and in severe cases, it may even cause patients to be unable to tolerate ultrasound radiation and terminate the treatment. There is currently no establishe...

Unsupervised restoration of a complex learned behavior after large-scale neuronal perturbation

This paper reports on research investigating how zebra finches recover their complex learned behaviors following large-scale neuronal perturbations. The researchers selectively disrupted the activity of the projection neurons in the HVC (hyperpallium ventralis) region critical for song sequence generation in zebra finches using genetic tools, leadi...

Closed-loop recruitment of striatal interneurons prevents compulsive-like grooming behaviors

Closed-loop recruitment of striatal interneurons prevents compulsive-like grooming behaviors

Obsessive-compulsive behaviors have long been associated with overactivation of the striatum. The GABA-ergic parvalbumin-positive interneurons (PVIs) in the striatum play a crucial role in regulating striatal activity and inhibiting inappropriate motivated behaviors. To investigate the potential role of striatal PVIs in regulating obsessive-compuls...
