Approaches and Limitations in the Investigation of Synaptic Transmission and Plasticity

open access: yesFrontiers in Synaptic Neuroscience, 2019
The numbers and strengths of synapses in the brain change throughout development, and even into adulthood, as synaptic inputs are added, eliminated, and refined in response to ongoing neural activity.

Intraoperative Characterization of Subthalamic Nucleus-to-Cortex Evoked Potentials in Parkinson’s Disease Deep Brain Stimulation

open access: yesFrontiers in Human Neuroscience, 2021
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a clinically effective tool for treating medically refractory Parkinson’s disease (PD), but its neural mechanisms remain debated.

Evoke: Evoking Critical Thinking Abilities in LLMs via Reviewer-Author Prompt Editing [PDF]

open access: yesarXiv, 2023
Large language models (LLMs) have made impressive progress in natural language processing. These models rely on proper human instructions (or prompts) to generate suitable responses. However, the potential of LLMs are not fully harnessed by commonly-used prompting methods: many human-in-the-loop algorithms employ ad-hoc procedures for prompt selection;

Intraoperative Neurophysiologic Examination in Central Nervous System Tumor Surgery: Four-year Single-institution Experience

open access: yesTürk Nöroloji Dergisi, 2017
Objective: Intraoperative neurophysiologic monitoring (IONM) is widely used nowadays to minimize neurologic morbidity in neurosurgical operations. Our goal was to describe the standard IONM techniques used in our center and to discuss our own clinical ...

Cortical Auditory Evoked Potentials in 2-Year-Old Subjects

open access: yesInternational Archives of Otorhinolaryngology, 2020
Introduction Cortical auditory evoked potentials (CAEPs) can be used to evaluate both peripheral and cortical components of auditory function, and contribute to the assessment of functional sensitivity and auditory thresholds, especially in neonates and ...

On the stimulus duty cycle in steady state visual evoked potential [PDF]

open access: yes, 2014
Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly

N2b Reflects the Cognitive Changes in Executive Functioning After Concussion: A Scoping Review

open access: yesFrontiers in Human Neuroscience, 2020
Objectives: The N2b is an event-related potential (ERP) component thought to index higher-order executive function. While the impact of concussion on executive functioning is frequently discussed in the literature, limited research has been done on the ...

What is the effect of benzodiazepines on deep brain activity? A study in pediatric patients with dystonia

open access: yesFrontiers in Neurology, 2023
IntroductionBenzodiazepines (BDZs) are commonly used to treat the symptoms of movement disorders; however, deep brain stimulation (DBS) has become a popular treatment for these disorders.

Extinction of cue-evoked drug-seeking relies on degrading hierarchical instrumental expectancies [PDF]

open access: yes, 2014
There has long been need for a behavioural intervention that attenuates cue-evoked drug-seeking, but the optimal method remains obscure. To address this, we report three approaches to extinguish cue-evoked drug-seeking measured in a Pavlovian to ...
